Abstract
Arden, G. and Y.‐M. Liu. Some responses of the lateral geniculate body of the rabbit to flickering light stimuli.The response of geniculate cells to flickering light shows differences from the responses of retinal ganglion cells. The evoked discharge is usually only loosely synchronised with the flicker and consists of a burst of impulses similar to a resting burst. In most cells both excitatory and inhibitory processes determine this discharge. Cells may follow a flicker by rhythmic inhibition of their resting activity. Alteration of the intensity of the stimulus does not greatly affect the number or frequency of the evoked spikes, but considerably alters the degree to which the spikes are synchronised with the flicker. These findings are discussed in relation to retinal electrophysiology and the way information is transmitted by the geniculate body.
