Figure 1.

Gamma oscillations are more prominent in BL than in LA or STR. A, Representative examples of LFPs (traces) and corresponding spectrogram (colored plots) for the STR (top), LA (middle), and BL (bottom). Data obtained from eight rats during intertrial intervals (112 in STR; 105 in LA; and 77 in BL). B, Average ± SEM power spectrum for BL (red; n = 77), LA (blue; n = 105), and STR (black, n = 112). Gray-shaded regions mark significantly different consecutive bins. C, Average ± SEM CSD power spectrum (three rats) for BL (red), LA (blue), and STR (black). Gray-shaded region marks significantly different consecutive bins in the gamma range. Data were obtained outside the task context, during epochs of quiet wakefulness.
