Research Interests for Kevin S LaBar

Research Interests: Emotional Memory

My research focuses on the neuroscience of emotion-cognition interactions in the human brain, with an emphasis on understanding how emotional events are linked to memory and attention systems. The laboratory combines studies of neurologic and psychiatric patients with studies of healthy adults using functional MRI, event-related potential and psychophysiological recording techniques. Our initial studies have shown that the amygdala is a critical brain structure involved in mediating arousal effects on both conditioned fear learning and explicit memory. Currently, this line of work is being extended to understand how the amygdala interacts with cortical brain regions at different stages of memory processing and the degree to which amygdala-dependent processing is under attentional and executive control.
