Document Summary
Traumatic brain injury-> a wound to the brain that results from a blow to the head. Scientific field of neuropsychology, the study of the relation between behavior and brain function. Neuropsychology draws information from many disciplines anatomy, biology, biophysics, ethology, pharmacology, physiology, physiological psychology, and philosophy among them. The brain has two almost assymetric halves called hemispheres on the left side and right side. Psychology has a long part but only a short history: the written record for understanding ourselves and society is limited. Removal of the cortex did not appear to eliminate any function completely, though it seemed to reduce all functions to some extent. This demonstration appeared to be a strong argument against localization of function and even to cast doubt on the role of the cortex in behavior. Each hemisphere has its own higher gnostic functions, and uses its own percepts, mental images, associations and ideas.
