Theta ratio increases significantly after Fx, but not MTT stimulation. Low T-ratio (A) and high T-ratio (B) values following fornix-mediated LFS and subsequent HFS. * P<0.05, ** P<0.01. The numbers above the symbols denote the timing of LFP epochs on the color-coded power spectrograms below: (1) a sample epoch of the power spectrum during the baseline recording period (C), while (2) a sample epoch of the power spectrum during the subsequent post-LFS period (D). Note power increases in the 3.5–4.5 Hz range. Low T-ratio (E) and high T-ratio (F) values following MTT-mediated LFS and subsequent HFS. The numbers above the symbols denote timing of LFP epochs on the color-coded power spectrograms below: (3) represents an example epoch of the power spectrum during baseline period (G), whereas (4) shows an example epoch of the power spectrum during the subsequent post-LFS period (H).
