Forebrain

The forebrain, or prosencepalon, is the most forward part of the physical brain. The forebrain separates into the diencephalon (composed of the thalamus, hypothalamus, subthalamus, epithalamus and pretectum) and the telencephalon which develops into the cerebrum. The cerebrum itself consists of the cerebral cortex, with its underlying white matter, and the basal ganglia. The forebrain controls (amongst many other functions) body temperature, reproductive functions, eating, sleeping, and emotional display.
