Abstract

Visual cortical neurons generate synchronous oscillations depending on the coherent features in the visual field. This property may serve to bind the distributed neuronal activities into a unique representation. By applying a plannar multielectrode array to the retina isolated from the frog eye, we recorded light-evoked spike discharges from multiple OFF-sustained ganglion cells (dimming detectors) and demonstrated the presence of synchronous oscillations with the correlation analysis (~30 Hz [1]). In the present study, we examined the stimulus dependence of synchronous oscillations and their neural basis. The time domain of the stimulus intensity was sinusoidally modulated at 0.25 Hz while its spatial domain was kept constant.
