Cornell Chronicle, March 19, 2019

by Stephen D'Angelo

Researchers long ago mapped sight, hearing and other human sensory systems in the brain. But for taste, which could be considered our most pleasurable sense, precisely where the “gustatory” cortex is and how it works has been a mystery.

Using functional magnetic resonance imaging (fMRI) and a new method of statistical analysis, researchers have discovered the taste center in the human brain by uncovering which parts of the brain distinguish different types of tastes.

Adam Anderson

“We have known that tastes activate the human brain for some time, but not where primary taste types such as sweet, sour, salty and bitter are distinguished,” said Adam Anderson, professor of human development in the College of Human Ecology and senior author of the study, “Distinct Representations of Basic Taste Qualities in the Human Gustatory Cortex,” published March 5 in Nature Communications.

“By using some new techniques that analyze fine-grained activity patterns, we found a specific portion of the insular cortex – an older cortex in the brain hidden behind the neocortex – represents distinct tastes,” Anderson said.

The insular cortex, which separates the frontal and temporal lobes, has long been thought to be the primary sensory area for taste. It also plays a role in other important functions, including visceral and emotional experience.

“The insular cortex represents experiences from inside our bodies,” Anderson said. “So taste is a bit like perceiving our own bodies, which is very different from other external senses such as sight, touch, hearing or smell.”

Previous work has shown a nearby insular region processes information originating from inside the body – from the heart and lungs, for example. In this way, distinct tastes and their associated pleasures may reflect the needs of our body. Taste not only reflects what is on our tongue but also our body’s need for specific nutrients, Anderson said.

The researchers found evidence that could be considered the “sweet” spot in the insula – a specific area where a large ensemble of neurons respond to sweetness stimulation on the tongue.

“While we identified a potential ‘sweet’ spot, its precise location differed across people and this same spot responded to other tastes, but with distinct patterns of activity,” Anderson said. “To know what people are tasting, we have to take into account not only where in the insula is stimulated, but also how.”

Compared with previous animal studies that show distinct activation clusters of basic tastes in the brain, the new study’s results reveal a more complex taste map in the human brain, Anderson said, where the same insular region represents multiple tastes.

“One of the difficulties in prior work on the connection between the brain and taste specifically is that tastes come with strong associated hedonic responses, like sweet tastes good and bitter bad,” he said. “So we have not known if these taste regions are really dedicated to taste, but rather hedonics or palatability of taste. Our research also identified patterns distinguishing liking from disliking in the insula that were distinct from those representing taste quality.”

By comparing different compounds that result in similar taste quality, like the sweetness of glucose versus sucralose, the study also demonstrated that the insula represents taste quality, i.e., “sweet” and not just specific chemicals.

“That we have found a specific region in the insular that distinguishes primary tastes from each other as well as from subjective liking and disliking has provided strong evidence of where and how taste is represented in the human brain,” he said. “While we have long known the cortical areas for our external senses, we now have strong evidence for human gustatory cortex.”

Contributing to the study were Junichi Chikazoe, former postdoctoral researcher in Anderson’s Affect and Cognition Lab; and researchers from Columbia University and the University of Colorado. Funding was provided by the Canadian Institutes of Health Research, the Japan Society for the Promotion of Science and the Takeda Science Foundation.

Crossing Disciplines and the Lifespan

Qi Wang, Chair of Department of Human Development

Reprinted from APS.org, September 28, 2018.

In a new recurring feature, the Observer showcases university labs and departments that have advanced integrative science. In the inaugural installment, APS Fellow Qi Wang talks about Cornell University’s Department of Human Development, which she chairs.   

 

What is the history of the department? What was its genesis?

The Department of Human Development at Cornell University is an interdisciplinary entity that uses multiple approaches, methods, and levels of analysis to study human development across the lifespan and integrates basic and translational research to enhance development and well-being in diverse contexts and populations. The department distinguishes itself with an ecological view of development as unfolding in multiple overlapping contexts. It has consistently been ranked as one of the top human development programs in the country.

The department, founded in 1925, was one of the first departments in the United States established by a university that focused on child development within the context of the family. Over the past 90 years, the mission of the department has expanded to include the full lifespan: Adolescence and emerging adulthood were added to early childhood development during the 1960s, and adulthood and aging were added during the 1980s. The study of contextual influences has expanded outside of the family to a greater number and variety of contexts, including peer groups, schools, neighborhoods, and workplaces. The faculty have come to include scholars of multiple disciplines and methodologies. Currently, the department has a professorial faculty of 24. Undergraduate majors typically number between 250 and 300, with approximately 35 masters and doctoral students in residence.

How has it evolved over the years?

The department has become increasingly dynamic and integrative. It has maintained its ecological focus, exemplified by the influential work of APS James McKeen Cattell Fellow Urie Bronfenbrenner, APS Past Board Member Steve Ceci, and others, and in the meantime has redefined the ecological perspective to align with the development of the general field. This is reflected in our study of an increasing number and variety of contexts and their interactions with developmental (social, cognitive, biological) processes across the lifespan. We increasingly emphasize interdisciplinary and integrative approaches that span areas of psychology (cognitive, developmental, clinical, social, cultural), along with law, neuroscience, sociology, education, and history. We recently recruited a computational political scientist who studies social networks, political communication, online social support, and health. The department also has evolved to increasingly focus on culture and diversity, examining basic developmental processes in relation to a variety of demographic factors including socioeconomic status, gender, race and ethnicity, and cultural background.

Our interest in advanced methodologies is reflected in the addition of neuroscience, biological/life sciences, and data science in the department and in the importance we place on multiple levels of analysis. From the sociology and psychology of health and aging to the neuroscience of memory, emotions, and decision-making, the department mixes equally observational and correlational studies with rigorous experimental approaches and interventions within and outside the laboratory. The department has made a strong investment in neuroscience, being the only human development program in the country to house an MRI facility. The department is also unique among human development programs in housing a nonhuman animal laboratory, allowing us to lead examinations of lifespan developmental changes in the brain and behavior and how they are shaped by diverse environmental contexts, early life experiences, and genes and their expression. The recent addition of social networks research and data science further extends our interdisciplinary strengths.

The department embraces translational activities and “use-inspired research,” seeking evidence-based solutions for real-world problems. Both its pedagogy and outreach are research-based — often research conducted by the very faculty member teaching a particular course or engaging in a particular outreach activity.

How many faculty members are in the department? What departments or disciplines are represented?

The department has consistently attracted a distinguished faculty. Many mainstream psychological scientists have decided to join our faculty, with four of our newer faculty leaving tenured positions at top psychology programs. In the past year, we have recruited four assistant professors who are among the very best of their cohort. Several members of our faculty hold National Academy memberships, including the National Academy of Education, the American Academy of Arts and Sciences, and the National Academy of Medicine. Members of our faculty have garnered just about every prestigious award within psychological science, including the APS William James Fellow Award, the APS James McKeen Cattell Fellow Award, the G. Stanley Hall Award, the Society for Research in Child Development Senior Distinguished Contributions Award, and the E. L. Thorndike Award. The department has a professorial faculty of 24, from various disciplines within psychology, sociology, political and information science, and neuroscience.

The research topics of the faculty fall into three general areas: Law and Human Development (LHD), Health and Wellbeing (HW), and Cognition in Context (CC). All areas are characterized by interdisciplinary focus, lifespan perspective, cultural diversity, multiple approaches, methods, and levels of analysis, and integrative basic and translational research to study real-world problems.

The LHD area assembles a group of world-class psychologists and legal scholars to study the interplay of law, psychology, and human development. It offers a top-notch PhD–JD dual degree program. The HW area houses leading research on typical and atypical development across the lifespan in diverse populations. Faculty in this area examine the relation between mental and physical health in response to contextual factors and have produced groundbreaking and policy-shaping work. The CC area offers the most dynamic and rigorous investigations of the developing mind in interaction with a variety of biological, social, and cultural factors. Faculty conduct research using neuroimaging, EEG, cross-species modeling, field and laboratory experiments, and longitudinal designs to understand fundamental processes underlying human mind and behavior in context.

What would you describe as the most surprising or unexpected collaborations that psychological scientists have been able to join or lead within the department?

Every generation brings new scholars from diverse disciplines to our department. Their research transforms the department into new directions and in the meantime also is transformed by the interdisciplinary culture of the department. Often they collaborate across disciplinary lines. One example is an outstanding young neuroscientist we hired, who began a collaboration with a sociologist in HD who studies aging. It is the sort of collaboration that would be unlikely in a homogenous setting. There are many similar instances of cross-disciplinary collaborations to study machine learning, affective neuroscience, decision-making, and so forth, within and outside of the department. The disciplines that have been involved in HD faculty’s collaborative research include law, particle physics, mathematics, microbiology, biomedical engineering, business, behavioral economics, communication, and information science.

Here are some of the current cross-disciplinary collaborations of our faculty:

  • A cognitive developmental scientist is working with a sociologist from Cornell’s sociology department and a particle physicist at the Fermi Lab in Batavia, Illinois, to conduct a study on women in science.
  • A cognitive developmentalist is working with a law professor at the University of Michigan on children’s testimonial competence.
  • A sociologist is working with a team of physicians and health-care providers to conduct intervention research and policy analysis related to aging and health care, using evidence-based methods to develop a competent, caring, long-term care workforce.
  • An HD neuroscientist is working with an HD sociologist on Alzheimer’s disease research.
  • An HD member has had a long-term collaboration with a professor of pediatrics at another university around the evaluation of outcomes associated with the Nurse Family Partnership program.
  • A member of HD collaborates with a member of our business school faculty on cultural influences on bias.
  • A sociologist has been collaborating with both a pediatrics professor and an epidemiologist to examine the impact of poverty-related stressors on the cognitive and physical development of children in low-income families. She also works with two members of the Communications Department at Cornell to develop social-media use for health care among older adults.
  • Another member works with a pediatrician/public health scholar in another university on the projected behavioral impacts of global climate change.
  • An HD neuroscientist collaborates with a microbiologist here on the gut–brain axis and the biome.
  • Faculty from an education department, a mathematics department, and a veterinary school have also worked with our faculty members.

Has forming an interdisciplinary entity such as this made it easier or more challenging to obtain grant funding and get research published?

Our interdisciplinary focus has made us more competitive in obtaining grant funding and getting the research published. Specifically, our research often cuts across the more traditional categories of psychology and amplifies their applied nature.

On the one hand, our faculty has demonstrated “mainstream” excellence. Our publications appear in all of the top specialty psychological journals and the top general–general journals. Our faculty also frequently publish in top specialty journals in nondevelopmental core areas of psychology. In addition to the research being of the highest quality, a key reason for our success in publishing is that our research targets theoretical and empirical questions that our peers perceive as important, no matter whether they do or don’t fit into intuitive categories.

On the other hand, our faculty also excel in many integrative and interdisciplinary publishing outlets and make broad scholarly contributions beyond their core areas and beyond psychological science. Our publications also appear in nonpsychology journals such as those focused on sociology, education, anthropology, and medicine, and as a result our work has reached vastly different audiences. In addition to peer-reviewed articles in journals outside psychology, our faculty have also published a range of influential books, op-ed pieces, and Chronicle of Higher Education articles that address a wide range of audiences. Oftentimes, building a reputation for solid work in core psychological science journals opens up opportunities for important broader contributions.

Part of the “translation” and “interdisciplinary” process is collaborating with colleagues outside the disciplines in which we were trained. There are many good examples in our department as noted earlier. Pertaining to publication, for example, several faculty have collaborated with researchers in medical fields and published in major health-related journals with high impact factors, including The Journal of the American Medical Association, Pediatrics, Annals of Internal Medicine, New England Journal of Medicine, and the American Journal of Public Health.

What are the strategies that the department has utilized in maintaining its top-rank position in the field?

One strategy is related to our hiring priorities. We hire the best people available through open searches, without constraints based on current research areas or rank. We also actively seek opportunities to hire targeted senior faculty who are superstars in the field. We are fortunate to have a very supportive dean who lets us conduct open searches and prefill lines with strong candidates and who does not rescind lines after unsuccessful searches. In addition, our faculty overwhelmingly support hiring the best people, regardless of area.

Another strategy is to self-reflect on our current research topics and to allow the department to evolve as scholarship and policy needs change. Over the years, there have been important shifts in research emphases as fields have either changed direction or ceased to exist with faculty retirement or leave.

Another effective strategy is to establish a mentoring system for junior faculty. Each nontenured junior faculty in the department is provided with a mentoring committee as soon as he/she arrives on campus. The committee consists of three tenured faculty whose research is in a similar area as that of the junior faculty. The committee provides honest and constructive written feedback to the mentee at the end of each year, which is then discussed with the mentee in person as well as reported to the general faculty. The feedback acknowledges the mentee’s achievements in research, teaching, and service and in the meantime helps the mentee identify any issues so they can be effectively addressed early on. Because of this supportive system and because we strive to hire the best people in the first place, our junior faculty have been extremely successful in their work. Many have come to be leading researchers in their respective fields. We have four APS Rising Stars, and many junior faculty have received young investigator awards from major organizations. In the past 15 years, we have not had a single case of denied tenure.

According to a radical new model of emotion in the brain, a current treatment for the most common mental health problems could be ineffective or even detrimental to about 50 percent of the population.

Since the 1970s, hundreds of studies have suggested that each hemisphere of the brain is home to a specific type of emotion. The neural system for emotions linked to approaching and engaging with the world – like happiness, pride and anger – lives in the left side of the brain, while emotions associated with avoidance – like disgust and fear – are housed in the right.

Daniel Casasanto, associate professor of human development and of psychology, adjusts electrodes on the scalp of a study participant.

But those studies were done almost exclusively on right-handed people. That simple fact has given us a skewed understanding of how emotion works in the brain, according to Daniel Casasanto, associate professor of human development and of psychology.

That long-standing model is, in fact, reversed in left-handed people, whose emotions like alertness and determination are housed in the right side of their brains, Casasanto suggests in a new study. Even more radical: The location of a person’s neural systems for emotion depends on whether they are left-handed, right-handed or somewhere in between, the research shows.

“The old model suggests that each hemisphere is specialized for one type of emotion, but that’s not true,” Casasanto said. “Approach emotions are smeared over both hemispheres according to the direction and degree of your handedness … . The big theoretical shift is, we’re saying emotion in the brain isn’t its own system. Emotion in the cerebral cortex is built upon neural systems for motor action.”

The study, “Approach motivation in human cerebral cortex,” appeared June 18 in Philosophical Transactions of the Royal Society B: Biological Sciences. The paper’s first author, Geoffrey Brookshire, was a doctoral candidate in Casasanto’s lab at the University of Chicago and a visiting doctoral student in Casasanto’s lab at Cornell.

The idea for the researchers’ theory, called the “sword and shield” hypothesis, stems from Casasanto’s observation that we use our dominant hands for approach-oriented actions, while nondominant hands are used for avoidance movements.

“You would wield the sword in your dominant hand to make approach-related actions like stabbing your enemy, and use the shield in your nondominant hand to fend off attack,” he said. “Your dominant hand gets the thing you want and your nondominant hand pushes away the thing you don’t.”

The researchers theorized that approach and avoidance emotions are built on neural systems for approach and avoidance actions.

“If this sword and shield hypothesis is correct,” he said, “then three things should follow: Approach motivation should be mediated by the left hemisphere in strong right-handers, as it has been in tons of previous studies. But it should completely reverse in strong left-handers. For everyone in the middle of the handedness spectrum, approach emotions should depend on both hemispheres.”

Casasanto and Brookshire tested this idea by stimulating the two hemispheres of the brains of 25 healthy participants with a pain-free electrical current. The goal was to see if they could cause the participants to experience approach-related emotions – including enthusiasm, interest, strength, excitement, determination and alertness – depending on which hemisphere of the brain was stimulated and whether they were righties or lefties or somewhere in between. The study participants got zapped for 20 minutes a day for five days, and reported before and after the five days how strongly they were feeling emotions like pride and happiness.

The experiment worked – and corroborated the researchers’ first test of the sword and shield hypothesis using brain imaging. Strong righties who were zapped in the left hemisphere experienced a boost in positive emotions. So did strong lefties zapped in the right hemisphere. But when lefties are zapped in the left hemisphere – or righties in the right – “you see either no change or a detriment in the experience of these emotions,” Casasanto said.

The work has implications for a current treatment for recalcitrant anxiety and depression called neural therapy. Similar to the technique used in the study and approved by the Food and Drug Administration, it involves a mild electrical stimulation or a magnetic stimulation to the left side of the brain, to encourage approach-related emotions.

But Casasanto’s work suggests the treatment could be damaging for left-handed patients. Stimulation on the left would decrease life-affirming approach emotions. “If you give left-handers the standard treatment, you’re probably going to make them worse,” Casasanto said.

“And because many people are neither strongly right- nor left-handed, the stimulation won’t make any difference for them, because their approach emotions are distributed across both hemispheres,” he said.

“This suggests strong righties should get the normal treatment, but they make up only 50 percent of the population. Strong lefties should get the opposite treatment, and people in the middle shouldn’t get the treatment at all.”

However, Casasanto cautions that this research studied only healthy participants and more work is needed to extend these findings to a clinical setting.

The research was funded by a James S. McDonnell Foundation Scholar Award and the National Science Foundation.

A pair of key differences in the brain may help distinguish which seniors are at risk of falling prey to financial scams, a small new study suggests.

The first-of-its-kind study found a biological basis -- rather than poor decision-making skills -- underlying financial exploitation in the elderly. These findings might lead to a way to predict which seniors are susceptible to scams, the researchers said.

Such scams affect about 5 percent of older adults after age 60, said study author Nathan Spreng. He’s director of Cornell University’s Laboratory of Brain and Cognition.

“We suspect these are brain changes that occurred prior to [seniors] being exploited that rendered them vulnerable to exploitation... It could have been something that emerged as they were aging,” Spreng said.

“We think it’s probably more of an age-related change to the brain,” he added. “We don’t necessarily think this is a lifelong brain difference.”

About 45 million Americans were age 65 and older in 2013, according to the U.S. Census Bureau. The true incidence of financial scams in this age group is probably underestimated. Spreng said that many older adults are unaware that they were scammed or unwilling to report being exploited.

Prior research indicated that family members are the most common financial abusers of seniors. In Spreng’s study, a grandson continued to steal even after being confronted by the study participant. In other examples, a daughter charged $2,000 to a study participant’s account without permission, and a son’s girlfriend borrowed $4,000 and never paid it back.

Spreng and his team evaluated 13 older adults who had been robbed by family members or neighbors, or scammed online or by phone. The researchers compared that group to 13 peers who’d been exposed to a potentially exploitative scheme, but recognized and avoided it.

Forty-five behavioral tests were performed on both groups to measure aspects such as memory, personality, financial reasoning, and the ability to pay attention to information and evaluate it. Additionally, MRI scans were performed on the participants’ brains.

The only behavioral difference that emerged between the groups was more anger and hostility in those who’d been scammed. But the brain images were more telling: Exploited seniors showed more shrinkage and less connectivity in two key areas of the brain.

One brain region, known as the anterior insula, signals when something significant is happening. This area was significantly reduced in the exploited group of seniors, which suggests their brains weren’t signaling that they faced a risky situation, according to the study authors.

The other brain region, called the medial prefrontal cortex, helps read social cues, such as people’s intentions. The scammed seniors also showed more shrinkage and fewer neural connections in this area, the findings showed.

The researchers also found the networks of both affected brain regions were more connected to each other. This suggests the combination of effects might leave those seniors more vulnerable to scams.

S. Duke Han is a spokesperson for the American Federation for Aging Research. He said this study’s results are preliminary because of the small number of people studied.

“There also could be other reasons for why these brain imaging differences might be seen -- there may be differences in cardiovascular health, nutrition or another variable not accounted for, and this isn’t a large enough study to address those,” said Han.

Han and Spreng agreed that studying financial scams in the elderly is a difficult task.

“The topic can be seen as very embarrassing for older adults who become the victims of financial exploitation, so it’s hard to get them to agree to be recruited for this type of research,” Han said.

Larger studies are needed to confirm these findings and perhaps identify markers -- both biological and behavioral -- to identify who’s most at risk of scams, Spreng said.

“Overall, our objective is to help with identifying people who may be vulnerable but don’t know it, and help build up additional protections for them,” Spreng said.

“The consequences are just so devastating for people’s well-being and quality of life and, ultimately, their health when they lose their life savings. We’re trying to tackle this problem as a biological issue,” Spreng said.
