Event Abstract Back to Event First Spikes in V1 Are Phase Locked to Saccade-related LFP Oscillations Junji Ito1*, Pedro Maldonado2 and Sonja Grün1 1 RIKEN ,The University of Tokyo, Japan 2 Universidad de Chile, Chile During natural vision, primates perform frequent saccadic eye movements, using a short time window for each location's visual processing. In each fixation, individual neurons may contribute only with a few spikes for these complex computations, suggesting that visual features may be represented not only by spike counts but also by the precise timing of spikes. In the primary visual cortex of monkeys freely viewing natural images, we found a prominent beta-band local field potential (LFP) oscillation locked to the onset of saccades. Furthermore, the first visually evoked spikes were locked to a specific phase of this oscillation at about 60ms from the onset of visual fixation. We conclude that these saccade-triggered local changes could serve as a corollary signal to precisely modulate the timing of spikes occurring in V1 after the onset of a visual fixation, thus providing a substrate for a latency code and the occurrence of synchronous spikes.
