Module 10: Figure brain anatomy



Anatomy of the human brain.

The human brain has a number of discrete regions that carry out different functions. There is a large cortex that extends around towards the hippocampus. The middle of the brain has the corpus callosum, ventricles and the thalamus. Below the thalamus is the hypothalamus that extends down into the pituitary. The cerebellum at the back controls movement. The basal forebrain, midbrain and hindbrain contains the neurons that release transmitters, such as acetylcholine (ACh), 5-hydroxytryptamine (5-HT) and norepinephrine (NE) that constitute the ascending arousal system that controls the sleep/wake cycle.
