Synchronization in monkey visual cortex analyzed with an information-theoretic measure.
We apply an information-theoretic measure for phase synchrony to local field potentials (LFPs) [corrected] recorded with a multi-electrode array implanted in area V4 of the monkey visual cortex. We show for the first time statistically significant stimulus-dependent synchrony of the visual cortical LFPs and this during different, short time intervals of the response. Furthermore, we could compute waves of synchronous activity over the array and correlate their timing with the stimulus-dependent difference in synchrony [corrected]
