In the second experiment, we sought to identify which visual areas participate in remapping by scanning subjects during three trial types. In remapping trials, the stimulus appeared briefly and subjects made aurally cued saccades only after its offset. The first condition identifies voxels with lateralized visual responses. The second two conditions determine how eye movements affect the representation of visual stimuli. When subjects move their eyes during visual stimulation, the representation shifts from one hemisphere to the other.
Activation also occurs when the stimuli are extinguished prior to the eye movement.
This activation may be associated with updating the representation of salient stimuli when the eyes move. This linear response is characterized by a kernel matrix convoled with the stimulus. The kernel which is allowed to vary over time can capture the temporal dynamics of the cell, like it's response to moving objects. Using ensambles of neurons, a stimulus may be reconstructed using the associated kernels. The kernel of a cell may have additional uses, such as verifying the identity of a cell monitored by a permanently implanted electrode.
