The hypothalamus is a small portion of the brain performing a range of functions. Importantly, it links the nervous and the endocrine systems through the pituitary gland. It is located below the thalamus forming the floor of the third cerebral ventricle. This cone-shaped structure encompasses a control centre for a range of functions of the autonomic nervous system.
