Rhombencephalic phase of sleep in a decorticate cat (X1)
The two recordings are continuous.
Appearance of a spindle-like activity in the nucleus pontis caudalis (F.Rp) and concomitant disappearance of the EMG activity of neck muscles (EMG). Note the absence of slow waves m the subcortical structures before the rhombencephalic sleep. Numbers (1-2), (2-3) refer to bipolar recording through inferior (1), middle (2) and superior (3) leads of a tripolar electrode.
F.Rm: mesencephalic reticular formation.
Th: thalamus median.
HypoT: lateral hypothalamus.
Scale: 1 sec., 50 microvolts.
