Neurophysiology and Neuroanatomy
Neurophysiology is the study of the functions of the nervous system. Clinical neurophysiology is the study of the functions of the nervous system in the clinical setting, for diagnostics, treatment, and intensive care purposes. It is a broad field of study because many different levels are involved in the overall functioning of the nervous system and its components. This involves studying the relationship and pathways between the brain and the organs of the body and the nerves that connect them, both sensory, meaning nerves that receive input from sensors, and motor, meaning the nerves that activate muscle. Thus, neurophysiology studies nervous function ranging from individual nerve cells to the complex behaviours of the central nervous system. Additionally, the nervous system not only functions at the cell and system levels of organization, but also at a mechanistic level, that involves the study of the control or regulatory processes that occur.
