An important aspect of memory is the ability to recall the physical place, or context, in which an event occurred. For example, in recalling emotionally charged events such as the September 11 terror attacks or the assassination of President John F. Kennedy, we remember not only the event but also where we were when it happened. Indeed, in discussing such events with others, we often ask, “Where were you when … ?” Processing “where” information is also important for mundane events such as...[more]

Dr. Travis Todd, a Postdoctoral Fellow in Professor David Bucci’s laboratory, has received a National Research Service Award from the National Institute of Mental Health. Dr. Todd’s grant, entitled “Cortico-hippocampal Contributions to Context and Extinction Learning,” will focus on how a part of the brain known as the retrosplenial cortex (RSC) is involved in forming memories about fear-provoking stimuli. Importantly, this work will also emphasize the neural substrates of fear extinction...[more]
Female politicians’ success can be predicted by their facial features, especially in conservative states where women with more feminine faces tend to do better at the ballot box, a Dartmouth-led study finds.
The results suggest women’s electoral success requires a delicate balance between voters’ perception of traditional femininity and political competence. The study appeared in the journal Social Psychological and Personality Science and included researchers from UCLA and...[more]
Smith laboratory was awarded a 3-year research grant from the Whitehall Foundation. The award is to fund a project called “Brain Pathways for Adaptive Goal Seeking”. The project will use electrical recordings and optogenetics technology to understand how the brain makes goals valuable, and how that value can shift depending on internal states like changes in appetite.
Whitehall Award Description: The Whitehall Foundation is a not-for-profit...[more]

Peter Tse ’84, professor of psychological and brain sciences, is among 178 scholars, artists, and scientists in the United States and Canada awarded fellowships from the John Simon Guggenheim Memorial Foundation for 2014.
The fellows are selected “on the basis of prior achievement and exceptional promise,” according to the foundation. Tse, who holds a PhD in cognitive psychology from Harvard, is the author of The Neural Basis of Free Will: Criterial Causation (2013).
Jon Freeman, an assistant professor of psychological and brain sciences, is featured on Pacific Standard’s list of the 30 “top thinkers” under the age of 30.“
"My work examines how we perceive other people through facial, vocal, and bodily cues, as well as how those perceptions are shaped by the larger social context,” Freeman tells Pacific Standard.
Freeman, the director of the Social Cognitive and Neural Sciences Lab at Dartmouth, says, “Being able to shed...[more]
Professor Peter Tse ’84 has won two PROSE awards from the American Association of Publishers for his 2013 book, The Neural Basis of Free Will: Criterial Causation, which argues there is a physical pathway for choice in the human brain. Tse’s work, published by MIT Press, won the Award for Excellence in Biological & Life Sciences and was also recognized in the Biomedicine & Neuroscience category. The association names annual PROSE award winners among professional and...[more]
ARTICLE TITLE: A Dual Operator View of Habitual Behavior Reflecting Cortical and Striatal Dynamics
AUTHORS: Kyle S. Smith, Ann M. Graybiel

SUMMARY: Habits are notoriously difficult to break and, if broken, are usually replaced by new routines. To examine the neural basis of these characteristics, we recorded spike activity in cortical and striatal...[more]
Paper authored by Peter Tse and Alex Schiegel and published in the PNAS.
We do not know how the human brain mediates complex and creative behaviors such as artistic, scientific, and mathematical thought. Scholars theorize that these abilities require conscious experience as realized in a widespread neural network, or “mental workspace,” that represents and manipulates images, symbols, and other mental constructs across a...[more]
