Diencephalon: The diencephalon, along with the telencephalon (cerebrum) comprise the two major divisions of prosencephalon (forebrain). Main structures of the diencephalon include the hypothalamus, thalamus, epithalamus (including the pineal gland), and subthalamus.The diencephalon relays sensory information between brain regions and controls many autonomic functions of the peripheral nervous system.unction: The diencephalon is involved in several functions of the body including: 1  Directing Sense Impulses Throughout the Body. 2  Autonomic Function Control. 3  Endocrine Function Control. 4  Motor Function Control. 5  Homeostasis. 6  Hearing, Vision, Smell, and Taste. 7  Touch Perception.
Also known as the prosencephalon, the forebrain is mostly comprised of the cerebrum, which is divided into two hemispheres. The two main sections of the forebrain, however, are the telencephalon and the diencephalon.The telecephalon includes the cerebral cortex, the subcortical structures, and the corpus callosum, while the diencephalon includes the thalamus and the hypothalamus.he cerebrum includes the cerebral cortex, which is made up of four lobes: frontal, temporal, parietal and occipital. Imagining, planning and reasoning are some of the functions of the frontal lobe. Hearing and smelling, as well as forming memories and retrieving them later, are functions of the temporal lobes.
