Small Gray Matters has the scoop: V1 is the primary visual cortex–essentially, the first cortical stop for incoming visual information. The traditional view used to be that, because of their position at the bottom of the information-processing hierarchy, neurons in V1 respond only to very simple configurations of light patterns (e.g., specific spatial orientations or frequencies). That view is increasingly being challenged by anatomical data indicating that V1 receives projections from a variety of other cortical areas and functional data showing that V1 neurons respond to a variety of seemingly high-level properties.

Could it be that the delayed response visual activation may be related to the fact that one would need to imagine what the screen (with stimulus or without stimulus) had looke like earlier when making a delayed motor response?
