Arousal and RPS in a syndrome of
decortication

A. Arousal: Very low voltage EEG activity and considerable EMG activity at the frontal region and the biceps (hypertony of decortication). Periodic breathing.

B. RPS: Total disappearance of the EMG activity. Discrete rhythmic 3/sec slow waves at the vertex. Rapid eye movements (Y). Slowing of the EKG. Acceleration of respiration.

FDG: right and left frontal;
FDV: vertex-right frontal;
VOD: vertex-right occipItal.

Scale: 1 sec, 50 microV.
