Dr. Luca Turin discusses how cutting off the blood supply to the brain by inflating a cuff around the neck can lead to loss of consciousness in just seven seconds, which is a surprisingly short time given that the brain starts experiencing real problems from oxygen deprivation after two or three minutes. This suggests that the electron current going through mitochondria may be crucial for our consciousness, as it stops very rapidly when the brain is deprived of oxygen.
