Figure 1

I- Arousal.

II- Slow phase of sleep: slow waves and spindles at the cortical and reticular level. Persistence of EMG activity of the neck muscles (EMG).

III- Rhombencephalic phase of sleep (paradoxical phase). Fast cortical and reticular activity. Rhythmic activity at the dorsal hippocampal level (H.d.), spindles at the pontine reticular level (F.R.p.) and total disappearance of the EMG activity.

C.S.M.; C.A.: sensory motor cortex; acoustic cortex.

H.v.: ventral hippocampus.

F.R.m.: mesencephalic medial reticular formation in frontal planes of Horsley-Clark: Al and A2.

Time scale: 1 second, 50 microvolts.

In all figures, recordings are bipolar.
