About Your Brain
These articles give a basic overview of the brain and how it works.
This is a Neuron
The brain uses networks of these neurons, so small that 30,000 of them can fit on the head of a pin - to process information.
About Your Brain
First, put your two fists together, fingers touching. This is the size of your brain. It weighs about 3 pounds. Together, the brainstem and midbrain control breathing and heartbeat, sex drive, consciousness, and body temperature. The inner structures are surrounded by the wrinkly cortex - the thinking, processing part.
