Brain Regions
The brain has three major regions: the brainstem, midbrain and forebrain.
The brainstem is composed of the medulla, the part that controls breathing, blood pressure, heart rate and digestion, and the cerebellum which coordinates speech and muscle movement. It is the most primitive part of the brain, as it controls the most basic and essential functions in the body.
The midbrain contains the links between the brainstem and thalamus to transmit information, and also the hypothalamus to regulate action. The amygdala is associated with aggressive behavior. The hippocampus is associated with long-term memory, and amnesia is a result of damage in this part of the brain.
The forebrain develops into the cerebral cortex, and is associated with mind function such as reasoning, sensation and motion.
