Effects of 7 Hz MS stimulation on CA1 EEG. A. Density spectral array showing 7 Hz band during stimulation on (120 s) and during stimulation off (120 s) from a single EEG channel. The thick band is at 7 Hz with harmonics demonstrated. B. Power spectrum (left panel) and time-frequency display for 7 Hz stimulation off (left) and stimulation on (right) from a single channel. Time frequency displays were generated by averaging power over trials. With 7 Hz MS optogenetic stimulation there was a marked increase in theta power with time-frequency domination by 7 Hz activity. The panel is colour coded with the brighter colors demonstrating higher theta power.
