Theta and RR power in different behavioral states and recorded regions. Theta power during NREM sleep should be interpreted with care because there is no genuine theta rhythm during this period but only irregular activity in the theta range. Similarly, theta power during immobility may not represent a genuine immobility theta but may partly represent electrographic signs of drowsiness. A single power value was obtained for each rhythm, which was the power value at the same frequency as nasal respiration for RR and the power value at the same frequency as the highest CA1 power peak in the range of 4–12 Hz for theta. All power values were corrected by subtracting the fitting of the reciprocal of frequency (1/f) over 2-30 Hz. Bars and error bars represent mean ± SEM over animals. Resp, respiration.
