Proportion of electrodes showing significant theta oscillations, before (Pre, −750 to 50 ms) and after (Post, −50 to 750 ms) fixations to locations of interest. p-Values were computed using a binomial test, based on the total number of electrodes (N) for a subject or group. *p < 0.05, Bonferroni corrected across locations and time intervals.
