Average probability (Chi square test) and latency (ANOVA with Bonferroni test) of the synaptically evoked spikes are compared during baseline and following TBS (post-TBS). Columns at right show the overall spontaneous firing frequency in the baseline and at early (0–15 min) and late (from 15 min until the end of recording) post-TBS time windows including theta and non-theta periods
