A Neural Correlate of Working Memory in the Monkey Primary Visual Cortex
Hans Supèr,12*Henk Spekreijse,1Victor A. F. Lamme12
The brain frequently needs to store information for
short periods. In vision, this means that the perceptual correlate ofa
stimulus has to be maintained temporally once the stimulus hasbeen
removed from the visual scene. However, it is not known howthe visual
system transfers sensory information into a memorycomponent. Here, we
identify a neural correlate of working memoryin the monkey primary
visual cortex (V1). We propose that thiscomponent may link
sensory activity with memory activity.
