_The forebrain is the largest part of the brain, most of which is made up
of the cerebrum. Other important structures found in the forebrain
include the thalamus, the hypothalamus and the limbic system.
The cerebrum is divided into two cerebral hemispheres. Each hemisphere is divided into four lobes: frontal, parietal, occipital and temporal. The surface of each hemisphere is made up of grey matter known as the cerebral cortex and is highly folded to increase the cortical surface area available within the confines of the skull. The cortex controls perception, memory, and all higher cognitive functions, including the ability to concentrate, reason and think in abstract form.
The thalamus relays sensory information to the cerebral cortex and the hypothalamus regulates visceral functions, such as temperature, reproductive functions, eating, sleeping and the display of emotion. The limbic system is a collection of structures within the forebrain, including the amygdala hippocampus. Also known as the 'emotional brain', the limbic system is important in the formation of memories and in controlling emotions, decisions, motivation and learning.
