Different consequences of tetanisation are characterised by distinct profiles of changes in theta (5–10 Hz) and gamma (30–100 Hz) spectral power in the DG in vivo. (A) HFT-induced increase in theta spectral power is more prominent in LTP and STP, but not the failed potentiation group. (B) HFT induces an increase in gamma spectral power with the peak within first 100 seconds after stimulation. The results were pooled for 10 4-second-long epochs for each of five 100-seconds-long periods and are expressed as Mean ± SEM.
