Document Summary

Egyptians would do reserve bodies of important ppl for the afterlife, remove their most important organs (heart, liver) and put in jars, but would not preserve the brain. Aristotle appreciated that the brain was the important differences between humans and beasts. Neuroscience is the scientific study of the nervous system not behaviour (behaviour is affected though) Like a chicken with its head cut off. Mike the chicken went to cut chickens head off and missed, heated up the axe and when he cut off the chickens head, he also cauterized the wound. Mike the chicken lived for 18 months. Explaining the exuberance of the headless chicken. When he was decaptitated, there was a little bit of his brain stem left intact, allowing him to do basic chicken things and allowing him to live for 18 months. Feelings in body parts that no longer exist. Irritation at the ends of nerves, sends signals to brain.
