Physicians have made lots of experiments with carotid compression, mostly on animals. This study reports on experiments that have been done on humans with a "cervical pressure cuff". It contains details about anatomy including the possibility of occlusion of the vertebral arteries and clinical effects of arrest of cerebral circulation. Some interesting excerpts, the first two from an earlier study:
"In normal adult dogs of either sex, periods of arrest of circulation in the brain of six minutes or less, while producing severe functional changes for a time, were invariably followed by apparently complete functional recovery."
"The brain of the very young animal was much more resistent to arrest of blood flow than that of the adult while pregnancy or lactation increased the sensitivity of the brain to temporary arrest of circulation."
"Although the subject was instructed to remove his finger from the jet as soon as he felt like it, and thereby release the pressure in the cuff, he failed to do so, despite loss of consciousness and an anoxic convulsion."
