Abstract

top
Transient responses in the multineuronal activity along the visual path ways of encéphale isolé cats were studied during movements of the eyes across a source of light. The time course of the activity bursts depended on selective characteristics of the ocular movements. When the movements were active and "fast", the transient increase in firing rate of the geniculo-cortical and corticofugal neurons preceded the burst of activity photically evoked in the optic chiasma. When the movements were passive or, if active, "slow" the phasic responses in the optic chiasm appeared before the transient increases inthe central visual path neurons. In both fast and slow movements the oculomotor activation preceded chiasmatic and central visual firing. These results are discussed in relation to previous observations in dark-adapted cats of transient increases in geniculo-cortical and cortico fugal multineuronal activity, without changes in the optic chiasma activity, coincident with active and fast eye movements. The significance of these observations in relation to the "corollary discharge" theory is also discussed.
