Document Summary
The brain is made up of 100 billion neurons and a typical cortical neuron can have between 1 and 10,000 connections with other neurons. Rene descartes: mind seen as separate entity existing outside of our biology yet in control of actions and thoughts. Physical brain serves as connection between mind and body. Receptive zone: receive signals from other neurons. Made up of dendrites branching out from the cell body. The cell body contains most of the vital organelles which keep it functioning. Dendrites reach out to other neurons and receive signals to be relayed through a dendritic branch to the cell body from there they can go down to the axon. Transmission zone: passes on signals to other cells. Made up of the axon and terminal boutons. Axon: a long fibre that varies in length. Terminal boutons: cluster of branches at the end of the axon.
