DESCRIPTION:Perceptual decision-making is our ability to choose and perfor
 m appropriate motor acts based on learned sensory cues to achieve goals. T
 he objective of my lab is to understand the neural circuit dynamics underl
 ying this process of perceptual decision-making. In this three-part talk\,
  I will present our current understanding of the decision-related dynamics
  in dorsal premotor cortex (PMd)\, a brain area implicated in selecting li
 mb movements based on sensory cues. I will first present results that sugg
 est that superficial layers of PMd signal action choice earlier than the d
 eeper layers of PMd. I will then use analysis of neural population dynamic
 s in PMd during decisions and show that models that posit an urgency signa
 l provide better descriptions of neural dynamics and behavior compared to 
 simple accumulator models. Finally\, in the third and final part\, I will 
 discuss my recent work on using multi-area recurrent neural network models
  to model decision-related neural dynamics.
