SUMMARY:Cortical Ensemble Dynamics of Naturalistic Decision-making
DESCRIPTION:<p>Don Katz (Brandeis)<br><br>Most of life’s choices are made suddenly, and at variable delays following stimulus presentation. In this talk, I will reveal choice-related neural ensemble activity to be consistent with this description: whereas by standard single-neuron analyses cortical responses to tastes appear to increasingly predict upcoming consumption decisions (i.e., reflect stimulus palatability) across the 500 ms preceding the onset of ingestive behaviors, analysis of simultaneously-recorded neural ensembles reveals this choice-related activity to appear in nearly instantaneous, coherent ensemble state transitions. Furthermore, these ensemble transitions into choice-related firing, analyzed in single trials, accurately predict the timing of naturalistic choice behavior. These data suggest a novel, dynamical characterization of perceptual neural processing.</p>
