Figure 5. Dentate neurons tend to fire with gamma bursts.
Raster plots of unit firing during gamma burst epochs show increases in firing rate during bursting events. Top panel: Raw LFP from probe contact located in the hilus. Middle panel: Raster plots from a selection of units recorded simultaneously with the above LFP. Bottom panel: LFP trace filtered for theta (3-8 Hz) (red) and gamma (25-80 Hz) (green). The raw trace is repeated in gray for comparison. Gamma burst epochs as identified by a gamma power algorithm (see Methods and Supp. Fig. 4) are indicated in black.
