THE BRAIN

The brain is the main control centre of the central nervous system. It consists of three major parts :

The Cerebrum - largest part - wrinkled grey mass divided into left and right hemispheres. Involved in consciousness and higher functions.

The Cerebellum - small rounded part beneath the cerebrum - controls complex muscular movements.

Brain Stem - connects brain to spinal cord and controls basic functions (eg. temperature regulation, anger, fear, etc)

Memory is the ability of the brain to store information

eg. Sensory memory - depends on vision and only lasts for a short time (eg. navigating around a room in which the lights have just been
switched off). Controlled by the outer layer of the cerebrum (cerebral cortex)

Long Term and Short Term memory - controlled by the Hippocampus
