Neuropsychologist A neuropsychologist is a professional in the field of psychology that focuses on the interrelationships between neurological processes and behavior. They work as a team with neurologists, neurosurgeons, and primary care physicians. Neuropsychologists extensively study the anatomy, pathology, and physiology of the nervous system (http://www.tbidoc.com/Appel2.html). Clinical neuropsychologists then apply this knowledge to the assessment, diagnosis, treatment, and/or rehabilitation of patients across the lifespan with medical, neurodevelopmental, neurological and psychiatric conditions, as well as other cognitive and learning disorders (http://nanonline.org/content/text/paio/defneuropsych.shtm).…show more content…
Anatomically the hypothalamus is divided into three subdivisions: a periventricular region, medial region, and lateral region (Reber, 2001). The periventricular region contains many neurosecretory cells that serve as a part of control that the hypothalamus exerts over the pituitary gland. The medial region contains a number of hypothalamic nuclei, including the dorsomedial, paraventricular, supraoptic, and ventromedial. The lateral region contains a complex system of neural pathways (those of the medial forebrain bundle) and a collection of axons and cell bodies. The hypothalamus has many widespread connections with the rest of the forebrain and midbrain (Wiederholt, 2000). It contains many distinct nuclei. Through both the nerves and the hypothalamic hormones, the hypothalamus conveys messages to the pituitary gland, altering the release of hormones. Damage to the hypothalamic nucleus leads to abnormalities in one or more motivated behaviors, such as activity level, drinking, feeding, fighting, sexual behavior, and temperature regulation (Kalat, 2004). As a result of these effects, the hypothalamus attracts a great deal of research attention. Some of the behavioral changes which can occur in patients with lesions or tumors on the hypothalamus have been studied
