AB There are limitations in relating any single measure of spontaneous brain activity (such as amplitude of the EEG) to the onset of unconsciousness following stunning or slaughter. Conceptually, it is easier to assess the onset of loss of brain activity (isoelectric EEG) or loss of brain responsiveness (evoked potentials), and these provide a measure of profound brain failure that approaches brain death. In physiological terms, a stunning method that induces an instantaneous loss of evoked response and results in an isoelectric EEG would produce an unequivocal stun. The captive bolt is the only method that has so far been demonstrated to produce this effect. This does not mean to say that other methods fail to stun, it merely indicates that they produce a less profound insult to the brain.
