OxTalks is Changing
During Michaelmas Term, OxTalks will be moving to a new platform (full details are available on the Staff Gateway).
For now, continue using the current page and event submission process (freeze period dates to be advised).

Detecting covert decision dynamics from neural population recordings in primate motor cortex
The neural mechanisms underlying decision-making are typically inferred from the average activity from sequentially recorded single neurons, which obscures important aspects of decision-making dynamics. I will show that covert decision variables (DV) can be tracked dynamically on single behavioral trials via simultaneous recording of large neural populations in primate motor cortex. I will also show—in nonhuman primates under the conditions of our experiments—that decisions are encoded by relatively stationary populations of neurons, not by sequences of activity passed from neuron-to-neuron.
