Basic firing properties of CA3 neurons during Familiar sessions. A, Raw spike waveform examples from control (left) and DG-lesion (right) groups. For each unit, the average spike waveforms from four channels of a tetrode are shown. The scale bars indicate waveform amplitude (vertical) and width (horizontal). B, Basic firing properties (spike width, mean firing rate, peak firing rate, burst index) of CA3 cells from the two groups during the Familiar sessions (N = 142 neurons). No significant differences were observed.
