PT journal article

AB The relative humaneness of asphyxia and decapitation was objectively evaluated in rats by EEG monitoring. EEG activation (low voltage, last activity) was considered to indicate discomfort, pain, and affective responses to euthanasia. Such activation was present 37.3 +/- 7.5 sec after asphyxia and 13.6 +/- 4.6 sec after decapitation. Decapitation was also characterized by an immediate, large, and relatively long-lasting, ultra-slow voltage, detected by non-polarizable scalp electrodes. Isoelectric activity (death) occurred 69.4 +/- 9.9 sec after onset of asphyxia and 27.2 +/- 4.4 sec after decapitation.
