We have two major areas of the sensorimotor association cortex. One is the posterior parietal association cortex and the other the dorsolateral prefrontal association cortex. The posterior parietal association cortex is one of the brain regions in which controls sensorimotor functions. The poster parietal association cortex integrates sensory information such

the brain. The cerebral cortex maybe be broken up into four lobes. Each lobe is named after the bones of the skull that cover them. In the very front is the frontal lobe‚ and behind that is the parietal lobe. At the very back of the brain we find the occipital lobe. And curving around each side of the brain we find the temporal lobe. Because the brain is made of two hemispheres there are pairs of each lobe. Frontal lobe: The most forward of the four lobes of the cerebral cortex is the frontal

Over the course of history‚ people have been awed by the power and complexity of the human behavior‚ but it wasn’t until the 19th century that psychology became a real science. At first‚ it was hard to determine how psychology would interpret human behavior and the wonders of the mind. Originally it was thought to be a part of philosophy. However‚ after years of research‚ some psychologists decided they did not want to be part of philosophical world and commit themselves to full scientific psychological

Develop an outline of the components of the human nervous system‚ inclusive of the CNS (central nervous system) the somatic system‚ and both divisions of the autonomic nervous system (ANS). Include in your outline the major distinctions among these systems. Human Nervous System – Overview The human nervous system is composed of all nerve tissues in the body. The functions of nerve tissue are to receive stimuli‚ transmit stimuli to nervous centers‚ and to initiate response
