will speak on
Processing of rapid image sequences in the visual cortex
Abstract:
How do visual areas interact to generate a representation of the environment? We
presented macaques with a continuous stream of images at rates up to 72 images/s
and recorded from cells in high-level visual
cortex. Surprisingly, even at the highest rate (one image every 14ms), 60% of STS
neurons tested retained their stimulus selectivity. At these rates, information
about 7 independent stimuli are present in the visual stream, without causing
total failure of processing. These finding constrain models of visual processing
and representation.
The lecture will take place in the
