Summary
The visual, auditory, olfactory and vestibular receptors of one adult dog and 30 adult cats were excluded on both sides during the same operation by a procedure elaborated earlier by the same authors. The paper describes the dog's behavior and data on the duration of sleep and wakefulness observed for 7 months after operation. It was demonstrated that exclusion of the receptors mentioned in adult dogs is not followed by uninterrupted sleep. Sleep and wakefulness succeeded one another and the duration of daytime sleep did not differ from normal. Awakening occurred spontaneously or was easily caused by touch.
Cats, on the contrary, deprived of the same receptors, developed profound sleep inhibition. Spontaneous awakening occurred only for urination and defecation and did not last longer than 1–2 minutes. The behavior of the cats after the operation is described.
