Colloquium by Dr. Erin Rich, Department of Neuroscience, Icahn School of Medicine at Mount Sinai, New
Cognitive processes depend on the collective activity of populations of neurons.
Together, interacting neurons produce complex dynamics that may reveal key mechanisms linking
neuron firing to thought and behavior. In this talk, I will discuss our recent work investigating the
rich dynamics of population activity in the prefrontal cortex. Across different tasks requiring
evaluation, value-based decision-making, and working memory, neural populations reveal how
cognitive processes evolve and how relevant information is structured and restructured to meet task
demands. Together, these studies illustrate how population dynamics can provide important insights
into neural mechanisms of cognition that are poorly captured by examining single neurons in
Erin Rich is an Associate Professor in the Department of Neuroscience at Icahn School of Medicine at Mount
Sinai and the Friedman Brain Institute, which she joined in 2017. Her work focuses on the neural basis of
cognitive and affective processing. She and her team utilize behavioral and neurophysiological approaches
to study how rewards and punishments influence cognitive processes such as learning, memory and decision-
making. Erin Rich received a bachelor’s degree from Tufts University, an MD and PhD in Neuroscience
from Mount Sinai School of Medicine under the Medical Scientist Training Program. Prior to joining the
faculty, she was a post-doctoral fellow at the University of California, Berkeley. She received various prizes
and awards, the most recent being the FBI Research Scholars Award from the Friedman Brain Institute, Icahn
School of Medicine at Mount Sinai in 2019, the NARSAD Young Research Investigator Grant from Brain
and Behavior Research Foundation in 2019 and for Circuit mechanisms of self-organized cognitive strategies
from NIH/NIMH in 2020.
We organise the present talk as a an online lecture (Zoom details will follow). Credit Points can be obtained as usual as long as you participate for the whole duration of the talk.
