Desynchronized electroencephalogram in the deeply sleeping cat.

Electroencephalographic patterns of the different stages of sleep in the cat are shown, with special reference to a desynchronized deep sleep. This sleep stage is characterized by an increase in reticular stimulation arousal threshold and by the reappearance of 5 to 6 spikes per second on the electroencephalogram immediately after threshold behavioral arousal.

Electroencephalogram in the permanently isolated forebrain of the cat.

The cerebral cortex of cats with chronic or permanent mesencephalic transections of the brain stem showed both high-voltage, slow-wave synchronized electroencephalographic patterns and low- voltage, fast-wave desynchronized rhythms when studied postoperatively. The alternation of sleep and wakefulness electrical activity in the permanently isolated forebrain is contrasted with the observations of Bremer in the acute "cerveau isolé" preparation.
