Abstract

Perceptual learning (PL) improves sensory abilities through training and these improvements persist for long periods of time.
PL at the psychophysical level has been studied extensively, but changes in neuronal sensitivity and coding that may occur as learning progresses are poorly understood.
To investigate these neuronal changes, we engaged two macaque monkeys in a contrast discrimination task, where he had to judge whether a test stimulus had a higher or lower contrast compared to a sample stimulus. We recorded continuous multi-unit (envelope MUA) activity from chronically implanted electrodes (Utah arrays) in V1 and V4.
