I am writing a review paper describing the history (through the present day) of experiments designed to provide artificial support for maintaining normal brain activity following total circulatory or respiratory collapse. The ultimate goal of such research is to preserve normal brain function across lengthly periods (weeks/months) of cardiac or respiratory arrest. There is a very substantial scientific literature (a brief chronology of which is provided below) describing an increasingly successfull series of experiments where animal brains have been supported by artificial methods after complete circulatory and respiratory failure. If you are aware of any additional literature which should be included in this review or if you have comments regarding the appropriateness of this technology for current laboratory / distant future human clinical therapy please reply with an email note to annala@neuro.usc.edu. ------------------------------------------------------------------------------- 1812 -- Legallois put forth the original idea for resuscitating decapitated heads through the use of blood transfusion. 1836 -- Cooper showed in rabbits that compression of the carotid and vertebral arteries leads to death of an animal; such deaths can be prevented if the circulation of oxygenated blood to the brain is rapidly restored. 1857 -- Brown-Sequard decapitated a dog, waited ten minutes, attached four rubber tubes to the arterial trunks of the head, and injected blood containing oxygen by means of a syringe. Two or three minutes later voluntary movements of the eyes and muscles of the muzzle resumed. After cessation of oxygenated blood transfusion movements stopped. 1887 -- Laborde made what appears to be first recorded attempt to revive the heads of executed criminals by connecting the carotid artery of the severed human head to the carotid artery of a large dog. According to Laborde's account, in isolated experiments a partial restoration of brain function was attained. 1912 -- Heymans maintained life in an isolated dog's head by connecting the carotid artery and jugular vein of the severed head to the carotid artery and jugular vein of another dog. Partial functioning in the severed head was maintained for a few hours. 1928 -- Bryukhonenko and Cechulin showed life could be maintained in the severed head of a dog by connecting the carotid artery and jugular vein to an artificial circulation machine. ------------------------------------------------------------------------------- Chute-AL, Smyth-DH.
