Sensory Cortex: From 3 Different Sources
A region of the outer cerebrum of the brain in which sensory information comes to consciousness.Pressure, pain, and temperature sensations from the skin, muscles, joints, and organs are perceived in the parietal lobes, as is taste. Visual sensations are perceived in the occipital lobes at the back of the cerebrum; sound is perceived in the temporal lobes at the sides.
See BRAIN.
the region of the *cerebral cortex responsible for receiving incoming information relayed by sensory nerve pathways from all parts of the body. Different areas of cortex correspond to different parts of the body and to the various senses. Compare motor cortex.
The tissues that form the outer part of an organ and which are positioned just below the capsule or outer membrane. Examples are the cerebal cortex of the BRAIN and the renal cortex of the KIDNEYS.... cortex
A substantial reduction in the volume of SENSORY information impinging on the body – for instance, sitting in a dark, silent room. Prolonged deprivation is potentially harmful as the body needs constant stimulation in order to function normally. The main input organs are the eyes, ears, skin and nose. The absence of sensations disorients a person and results in neurological dysfunction. Some interrogation techniques involve sensory deprivation to ‘soften up’ the individual being questioned.... sensory deprivation
Description applied to the part of the nervous system dedicated to bringing information on sensations affecting the body to the brain. The opposite of sensory nerves is motor nerves; these carry instructions for action to the voluntary muscles in the body.... sensory
The outer covering of the two adrenal glands that lie atop each kidney. Embryonically derived from gonad tissue, they make steroid hormones that control electrolytes, the management of fuels, the rate of anabolism, the general response to stress, and maintenance of nonspecific resistance.... adrenal cortex
the intricately folded outer layer of the *cerebrum, making up some 40% of the brain by weight and composed of an estimated 15 thousand million neurons (see grey matter). This is the part of the brain most directly responsible for consciousness, with essential roles in perception, memory, thought, mental ability, and intellect, and it is responsible for initiating voluntary activity. It has connections, direct or indirect, with all parts of the body. The folding of the cortex provides a large surface area, the greater part lying in the clefts (sulci), which divide the upraised convolutions (gyri). On the basis of its microscopic appearance in section, the cortex is mapped into *Brodmann areas; it is also divided into functional regions; including *motor cortex, *sensory cortex, and *association areas. Within, and continuous with it, lies the *white matter, through which connection is made with the rest of the nervous system.... cerebral cortex
see exploding head syndrome.... episodic cranial sensory shock
the region of the *cerebral cortex that is responsible for initiating nerve impulses that bring about voluntary activity in the muscles of the body. It is possible to map out the cortex to show which of its areas is responsible for which particular part of the body. The motor cortex of the left cerebral hemisphere is responsible for muscular activity in the right side of the body.... motor cortex
a nerve that carries information inwards, from an outlying part of the body towards the central nervous system. Different sensory nerves convey information about temperature, pain, touch, taste, etc., to the brain. Compare motor nerve.... sensory nerve
