Primary visual cortex (V1) has direct reciprocal connections with posterior extrastriate areas V2, V3, V3A, V4 and MT (Refs1,3; red). (Not all back-projections to V1 are shown; extensive reciprocal connections between extrastriate areas are omitted.) Some of these posterior extrastriate areas...
Here, we develop a visually cued interval timing task that requires rats to decide when to perform an action following a brief visual stimulus. Using single-unit recordings and optogenetics in this task, we show that activity generated by the primary visual cortex (V1) embodies the target ...
The final stage of the network consists of edge detectors of various orienations arranged in a feature map, corresponding to the primary visual cortex, or V1. The lateral geniculate nucleus is modeled as a preprocessing stage. Excitatory forward and inhibitory backward connections exist between the...

Most of what we know on primary visual cortex (V1) comes from experiments performed under anesthesia. Yet visual cortex is typically used by awake animals while they actively navigate an environment. I will describe three studies currently performed in my ...

The visual system encodes the features of visual stimuli as well as their behavioral relevance. Stimuli with a high luminance contrast evoke more activity in the visual cortex than stimuli with a low contrast. At the same time, attended stimuli evoke more activity than nonattended stimuli. There...
