Woodman Receives 2016 Troland Research Award


The National Academy of Sciences has announced that Geoffrey Woodman, associate professor of psychology at Vanderbilt University, will receive a 2016 Troland Research Award.

The academy gives two of these $75,000 research awards annually to     recognize unusual achievement by young investigators and to further empirical research within the broad spectrum of experimental psychology.

Woodman has been working to unite techniques used to study the brain activity in humans with those used in animals, combining intracranial recordings in monkeys with scalp recordings. Such work is helping to bridge the gap between research in humans and primates.

Woodman has also made discoveries at the forefront of research on learning and memory. Recently he discovered that a mild electrical stimulation applied to the medial frontal cortex resulted in improved learning and memory for some five hours. These findings also have implications for people with brain disorders. Woodman and his team, for instance, have performed similar research on people with schizophrenia and found that the technique could restore error monitoring—the short but important pause healthy people make after making a mistake.

The Troland Research Award was established by a trust created in 1931 by the bequest of Harvard psychologist Leonard T. Troland. Woodman is the fourth Vanderbilt psychologist to receive the award. Previous award winners are Jeffrey Schall (1998), Isabel Gauthier (2008) and Frank Tong (2010).

The National Academy of Sciences is a private, nonprofit institution that was established under a congressional charter signed by President Abraham Lincoln in 1863. It recognizes achievement in science by election to membership, and — with the National Academy of Engineering, Institute of Medicine, and National Research Council — provides science, technology, and health policy advice to the federal government and other organizations.

Kevin Dieter, PhD and the lab of Dr. Randolph Blake receive a prestigious National Eye Institute NRSA grant

Project title: Psychophysical and neural correlates of eye dominance in human vision

Advisor: Randolph Blake

Consultants: Frank Tong, Psychological Sciences and Sean Donahue, Ophthalmology, Pediatrics, Neurology

Summary: While we effortlessly see a single, unitary visual world, it is easy to forget that this experience arises from two separate (left and right eye) views of the environment. The transformation from distinct monocular views to stable binocular single vision is the manifestation of important neural processes that give rise to significant improvements in visual perception, including stereoscopic depth perception and binocular contrast summation. In cases of sensory eye dominance (SED), a condition where one of the two eyes contributes more strongly to the binocular percept than the other, these gains can be muted or, in extreme instances, completely thwarted. Under these conditions, vision with two eyes is no better than with one, and in some instances is worse owing to monocular competition.

This project builds on the interesting recent discovery that SED may vary idiosyncratically throughout the visual field, potentially due to the local nature of visual mechanisms involved in combining neural signals from the two eyes. First, I will investigate how patterns of SED vary across visual field locations, and will test for influences of regional SED on binocular function. Then, I will apply functional magnetic resonance imaging (fMRI) to investigate how neural activity underlying visual field regions with strong SED imbalance differ from those sub-serving regions where both eyes contribute equally. Results from the proposed research can lead to a deeper understanding of typical and atypical binocular visual function, potentially leading to translational applications in the diagnosis and treatment of binocular visual disorders.

Gauthier selected 2015 Professor of the Year by SEC

Gauthier recognized by SEC as top teacher, researcher of 2015

Isabel Gauthier, David K. Wilson Professor of Psychology and professor of radiology and radiological sciences at Vanderbilt, has been selected as the 2015 Professor of the Year by the Southeastern Conference.

Her work at Vanderbilt has been exemplary, and she has distinguished herself as one of the most sought-after professors for Vanderbilt students of all levels.“Dr. Isabel Gauthier is a teacher, researcher and mentor who embodies the most desirable qualities we seek in the professoriate,” said Chancellor Nicholas S. Zeppos. “She has engaged in high-quality, high-impact research and attained an international reputation for her expertise in object recognition. Her work at Vanderbilt has been exemplary, and she has distinguished herself as one of the most sought-after professors for Vanderbilt students of all levels. I am thrilled she has been named the 2015 SEC Professor of the Year.”

Zeppos is the current chair of the SEC’s presidents and chancellors.

Each year, the SEC recognizes one faculty member from each of its 14 member universities who has excelled in teaching, research and scholarship with the Faculty Achievement Award. Each award winner receives a $5,000 honorarium from the SEC. To be eligible for the award, a professor must be a teacher or scholar at an SEC university; have achieved the rank of full professor; have a record of extraordinary teaching; and have a record of scholarship that is recognized nationally and/or internationally.

“The SEC is pleased to bestow the 2015 SEC Professor of the Year award on Dr. Isabel Gauthier,” said SEC Commissioner Mike Slive. “Her commitment to her students, to her research and to her field are virtually unmatched, and I congratulate Dr. Gauthier on this tremendous honor.”

The SEC Professor of the Year is selected from SEC Faculty Achievement Award winners, receives an additional $15,000 honorarium and is recognized at the SEC Awards Dinner in May and the SEC Symposium in September.

Gauthier’s research interests include the behavioral and neural study of visual object recognition, especially in domains of perceptual expertise such as faces, letters, musical notation, with implications for disorders likes autism and congenital face blindness. Her dissertation research demonstrated for the first time that the behavioral and neural underpinnings of perceptual expertise could be studied in the laboratory using short-term training protocols. Her work has demonstrated that the brain area which many experts thought specialized in face recognition also responds to other object categories, such as birds, planes or cars, in people who have expertise with these categories.

In 2000, Gauthier founded the Perceptual Expertise Network (PEN), which comprises more than 10 laboratories across North America and is now part of the National Science Foundation-funded Temporal Dynamics of Learning Center. With 30 workshops held in 15 years and hundreds of collaborative projects, PEN offers a new model of interdisciplinary collaboration centered on graduate student and post-doctoral fellow participation.

Gauthier has authored more than 110 peer-reviewed scientific articles, with 50 of these cited at least 50 times. Overall, her publications in many of the more prestigious journals in psychology and neuroscience have been cited more than 12,300 times.

She received the Young Investigator Award of the Cognitive Neuroscience Society in 2002, the American Psychological Association’s Distinguished Scientific Award for Early Career Contribution to Psychology in the area of Behavioral/Cognitive Neuroscience in 2003 and the Troland research award from the National Academy of Sciences in 2008 “for seminal experiments on the role of visual expertise in the recognition of complex objects including faces and for exploration of brain areas activated by this recognition.” She was elected Fellow of the Association for Psychological Science in 2010 and Fellow of the Society of Experimental Psychologists in 2012. In 2014, she received a Chancellor Award for Research from Vanderbilt University.

Gauthier teaches undergraduate Introductory Psychology and Brain Damage and Cognition and has taught Research Methods in Psychology. She has mentored several students in honors projects in her laboratory and has also received an award for the excellence of her graduate mentoring.

The SEC provosts select the SEC Faculty Achievement Award winners and the SEC Professor of the Year, and the program is administered by SECU, the academic initiative of the Southeastern Conference. SECU serves as the primary mechanism through which the collaborative academic endeavors and achievements of SEC students and faculty are promoted and advanced.


New faculty: Anita Disney explores role of neurotransmitters in attention

When Anita Disney was growing up in Adelaide, Australia, friends and family assumed she would become a scientist. After all, her father was a biologist and one of the founding faculty members of Flinders University.

But in what she admits may have been a bit of youthful rebellion, Disney gained admission to a performing arts magnet high school and threw herself into music, Shakespearean drama and dance classes. In college she pursued a bachelor of arts, majoring in drama. Then she encountered psychology.

“I got really stuck on this biological psychology course I took,” Disney said. She soon transferred to Australian National University, where she studied under the noted neuroscientist Michael B. Calford. He introduced her to neurosteroids, a special class of steroids made in the brain that modulate the activity of neurotransmitters, the chemicals that carry information throughout the brain.

During graduate studies at New York University, Disney worked with researchers studying the neurotransmitter acetylcholine. She came across what she thought was an extraordinary claim made by a British neuroscientist: Acetylcholine can sharpen cats’ vision. “I woke up one morning with the realization that I wanted to understand the role of acetylcholine in vision,” Disney said.

For her doctoral thesis, she studied the anatomy of the cholinergic system in the primary cortical vision region of macaques. During her postdoctoral training at The Salk Institute in San Diego, she invented a nanoprobe that can simultaneously monitor acetylcholine levels and electrical activity in the brain.

The probe allows Disney to explore the role that acetylcholine plays in attention and arousal. Rodent studies have shown that acetylcholine release into the cortex promotes attentive states, but the situation appears to be more complex in primates.

When human or nonhuman primates pay close attention to something, they generally concentrate on details in a relatively small area, causing elevated activity in the corresponding region of the visual cortex. “Critics object that the anatomy of release for acetylcholine is too widely spread in the cortex to produce such a focused effect,” Disney said. “Actually, we still know very little about the anatomy of this system, especially in primates.”

Disney theorizes that acetylcholine plays a general role in triggering attention, and another mechanism acts at a smaller scale to cause the local increase in sensitivity to a particular visual stimulus. “Think of the spectrum of capacities from ‘awake but not alert’ to ‘alert and highly attentive.’ I am certain that acetylcholine plays a role some place along this spectrum,” she said. “The question is, where?”

Using her nanoprobe, which Disney will be fabricating in the Vanderbilt Institute for Nanoscale Science and Engineering (VINSE) cleanroom, she plans to explore the cholinergic system in nonhuman primates. And using the functional MRI machines at Vanderbilt’s Institute of Imaging Science, she hopes to do similar studies in humans.

Congratulations to Alex Maier! Assistant Professor of Psychology Alexander Maier has been selected to receive the Society for Neuroscience’s Janett Rosenberg Trubatch Career Development Award for 2014.

The purpose of the award, which is given to only two individuals each year, is “to recognize individuals who have demonstrated originality and creativity in research and to promote success during academic transitions prior to tenure.”

Maier was recognized for his efforts to understand the basic mystery of how perception arises from neural activities. A prime focus of his research program is to differentiate between the neural circuitry that is involved in visual perception and sensory activity that does not attain the level of conscious awareness. His work has important implications for treating patients with visual disorders characterized by an inability to perceive or recognize certain types of visual images. He is also one of a handful of scientists studying the relationship between the electrical activity in the brain and the variations in blood flow that are measured by the brain mapping technique fMRI, the most commonly used and most reliable method for measuring neural responses in the human brain.

Brain study provides new insight into why haste makes waste

Why do our brains make more mistakes when we act quickly?

A new study demonstrates how the brain follows Ben Franklin’s famous dictum, “Take time for all things: great haste makes great waste.”

The research – conducted by Research Assistant Professor Richard Heitz and Jeffrey Schall, Ingram Professor of Neuroscience, at Vanderbilt University – has found that the brain actually switches into a special mode when pushed to make rapid decisions.

The study was published Nov. 7 in the journal Neuron.

“This is a question that is very basic to our experience as human beings, and something that we encounter on a daily basis,” Heitz, who designed and carried out the study, said. “If we can understand how our brain changes when we are pushed to respond faster, we have gone a long way toward understanding the decision-making process in general.”
