TI Pain perception in decapitated rat brain

QU Life Sciences 1991; 49(19): 1399-402

PT journal article

AB The question of humaneness of decapitation per se has been considered. The time required for the oxygen tension in decapitated rat brain to decline to a level at which the brain becomes unconscious was estimated to be 2.7 sec. Assuming that decapitation is a powerful arousal stimulus and that the resulting EEG activation (low voltage, fast activity) indicates a conscious awareness of pain and distress the maximum time the pain and distress could be perceived would be 2.7 sec. Hence, decapitation of rats per se may be considered humane.
