Average probability (Chi square test) and latency of synaptically evoked postsynaptic spikes (ANOVA with Bonferroni test) in the experiments during baseline and at two different periods following TBS (post-TBS). The overall spontaneous firing frequency in the baseline and at early (0–15 min) and late (15–45 min) post-TBS time windows are shown at right
