There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Dynamics of threat and reward processing in the human brain
Research on the emotional and motivational brain often employs relatively static paradigms, such as the presentation of emotion-laden faces. Because natural behaviors evolve temporally, advancing understanding of dynamic processes holds promise in opening new research avenues. In this presentation, I will discuss recent attempts to develop paradigms to study the dynamics of threat- and reward-related processes, as well as their interactions. I will also describe work exploring how recurrent neural networks can be used to characterize spatio-temporal dynamics as measured by functional MRI data, and how recurrent neural networks can be used to study more naturalistic/dynamic paradigms.
Biosketch: Luiz Pessoa obtained a PhD in computational neuroscience at Boston University. After his PhD he returned to his home country, Brazil, and joined the faculty of Computer Systems Engineering at the Federal University of Rio de Janeiro. After a few years, he returned to the US as a Visiting Fellow at the National Institute of Mental Health. He then joined the Department of Psychology at Brown University as an Assistant Professor, the Department of Psychological and Brain Sciences at Indiana University, Bloomington, as an Associate Professor, and since 2011 has been at the Department of Psychology, University of Maryland, College Park, where he is full Professor and Director of the Maryland Neuroimaging Center. His research interests center around the interactions between emotion/motivation and perception/cognition. He published in 2013 the book “The cognitive-emotional brain: from interactions to integration” and his book " The Entangled Brain: How Perception, Cognition, and Emotion Are Woven Together", also by MIT Press, is scheduled for to be published later this year.
