Hypnotoxin Theory of Sleep, circa 1938
Scope and Contents
Warning: this film includes procedures on research animals.
In this silent black and white film, cerebrospinal fluid in a dog is replaced by the same fluid from a fatigued dog in order to see if they “obtain” fatigue. Fluid is removed from unanesthetized dogs. Dogs are observed after fluid replacement and given sensory stimuli such as loud sounds and pricks from scissors to test their reactions.
Film by J.G. Schnedorf, and A. C. Ivy, Department of Physiology and Pharmacology, Northwestern University Medical School.
