Population Coding in Working Memory

Working memory underlies most higher cognitive functions. In order to hold a conversation, for instance, the content of the recently spoken sentence needs to be kept in memory in order to form the next coherent sentence. The aim of this project is to understand how neurons in the prefrontal cortex encode working memory, with special focus on how populations of neurons cooperate dynamically to sustain memories of visual stimuli when those stimuli are no longer available as sensory inputs. We conduct these studies using animals trained to encode and remember simple visual stimuli while implanted with chronic, multichannel recording electrodes.
