Document Summary
Life begins with conception, when a single cell, made from sperm and egg forms a zygote. This divides multiple times and everything that follows came from that single cell. From this point a neural tube forms, the bottom which become the spinal cord and top the brain. The brain is not wired at conception and connections between nerve cells are made in the womb. The video shows the incredible fest of development. There are 10000 nerve cells in one piece of brain the size of a grain of rice. There are trillions of connections and nerve cells. But how does the brain know how to connect itself and behave the way it does. Most of the cells in the body die and are replaced, i. e. skin cells ( 90pound of skin lost in a life time) but not neural cells. The ones you are born with, you will also die with.
