Consciousness, unconsciousness and death in the context of slaughter. Part I. Neurobiological mechanisms underlying stunning and killing
2016, Meat ScienceCitation Excerpt :In dogs, brain activity was lost in less than 15 s and somatosensory evoked potential (Box 3) in 4–6 min following complete cerebral ischemia (Hossmann, Lechtape-Gruter, & Hossmann, 1973). Most scientists believe that due to lack of oxygen, loss of consciousness takes place between 3 and 10 s after decapitation, despite the presence of a certain level of electrical activity in the brain (Derr, 1991; Rossen et al., 1943; Holson, 1992; but see Mikeska & Klemm, 1975). Overall, results show that the interruption of blood flow induces unconsciousness in seconds.
