Figure 4

Phase difference of theta oscillations recorded from different tetrodes located in the CA1 pyramidal cell layer. A, Examples of raw and filtered signals recorded simultaneously from 4 tetrodes located in the CA1 pyramidal cell layer of a control mouse. Filter bandpass: 5-14 Hz. B, Crosscorrelations of the filtered signals from A. The 6 possible pairs of tetrodes are shown. The peaks in the crosscorrelations are located near time lag 0, indicating that theta oscillations recorded on different tetrodes tended to have a similar phase. C, Distribution of theta phase shifts for all pairs of tetrodes located in the pyramidal cell layer of CA1 and recorded simultaneously. Data are shown separately for control and Cx36−/− mice.
