Figure 2. Discharge of the LPGi PS-Off neurons across the sleep-waking cycle.

Figure 2

A. Unit activity of a representative PS-Off neuron across a PS episode following SWS. This neuron ceases its discharge immediately after the initiation of the PS episode and recovers at the end of the PS episode. B. Firing rate of the 8 PS-Off neurons recorded in the LPGi across sleep-waking cycle. C. Firing rate of the PS-Off neurons recorded in the LPGi in the 3 vigilance states. Data are expressed as mean ± SEM, hello P≤0.05 vs SWS, # P≤0.05 vs PS. D. Number of spikes per 10s during the PS/W transition. E. Number of spikes during the SWS/PS transition. The majority of the PS-Off neurons stop firing immediately after the onset of PS.
