Document Summary
Typical cortical neuron can have between 1 and 10,000 connections with other neurons. Historical approach by descartes has been to separate the mental processes of the mid form the physical processes of the brain. Mind was seen as a separate entity existing outside of our biology, yet in control of our actions and thoughts. Physical brain was thought to serve in part as a connection between mind and body. Neuroscience can be studied alongside psychology at the level of molecules, cells, and systems of the brain to elucidate the mechanisms that underlie sophisticated mental abilities. Two zones to a neuron: receptive zone. Designed to receive signals from other neurons. Made up of dendrites branching off the cell body. Receives and relay signals down the axon. Begins with cell body, containing most of the vital organelles to keep the cell functioning.
