title: Effects of EEG synchronization on visual responses of the cat's geniculate relay cells: a comparison among Y, X and W cells.
abstract: Single unit activities of Y, X and W cells were recorded in the cat lateral geniculate nucleus to study how their responses to stationary light spots change with the cortical EEG. The shift from desynchronized to synchronized EEG drastically suppressed W cell activities, depressed both transient and sustained components of X cell responses, but did not affect the transient component of Y cell responses. This was ascribed to different inhibitory circuitries in the three parallel pathways and their differential modulation by the ascending brainstem activities.
