Painting of Diencephalon and brainstem:The diencephalon is located between the cerebral hemispheres and above the midbrain. .Structures of the diencephalon include the thalamus, hypothalamus, the optic tracts, optic chiasma, infundibulum, Ventricle III, mammillary bodies, posterior pituitary gland and the pineal gland. .Function: Chewing ,Directs Sense Impulses, Throughout the Body ,Equilibrium ,Eye Movement, Vision ,Facial Sensation ,Hearing ,Phonation ,Respiration ,Salivation, Swallowing ,Smell, Taste. The brainstem (or brain stem) is the lower part of the brain, adjoining and structurally continuous with the spinal cord. The brain stem provides the main motor and sensory innervation to the face and neck via the cranial nerves. Though small, this is an extremely important part of the brain as the nerve connections of the motor and sensory systems from the main part of the brain to the rest of the body pass through the brain stem. This includes the corticospinal tract (motor), the posterior column-medial lemniscus pathway (fine touch, vibration sensation and proprioception) and the spinothalamic tract (pain, temperature, itch and crude touch). The brain stem also plays an important role in the regulation of cardiac and respiratory function. It also regulates the central nervous system, and is pivotal in maintaining consciousness and regulating the sleep cycle. Some taxonomies describe the brain stem as the medulla oblongata (myelencephalon) and pons (part of metencephalon), whereas others include the midbrain (mesencephalon).
