No significant effects of local V1-lidocaine infusion on ACC responses to flash stimuli. a Average pre- and post-infusion responses for two examples, in which 0.4 μl lidocaine was applied in two ipsilateral V1 sites, and, for each infusion site, application was conducted via the same procedures as the experiments shown in Fig. 3 (c and d). b and c Summary of all experiments shown in (a) (n = 10). Bar in (b), drug infusion; traces in (c), pre- and post-infusion responses averaged across population data in reference to their peak times
