Table shows comparisons of the average probability (Chi square test) and latency (ANOVA with Bonferroni test) of the synaptically evoked postsynaptic spikes during baseline and following high-frequency theta-burst stimulation (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
