The cerebrum, originally functioning as part of the olfactory lobes, is involved with the more complex functions of the human brain. In…. The cerebral hemispheres consist of an inner core of myelinated nerve fibres, the white matter, and an outer cortex of gray matter.
The cerebrum is made up of the two cerebral hemispheres and their cortices, (the outer layers of grey matter), and the underlying regions of white matter. Its subcortical structures include the hippocampus, basal ganglia and olfactory bulb.
Hindbrain functions: The three regions of the hindbrain coordinates all processes necessary for survival. These induce breathing, heartbeat, sleep, wakefulness and motor learning. The cerebrum is the largest part of the brain. It consists of the cerebral cortex and other subcortical structures.
