| sensory aphasia | Aphasia in which there is impairment in the comprehension of spoken and written words, associated with effortless, articulated, but paraphrasic, speech and writing; malformed words, substitute words, and enologisms are charcteristic. When severe, and speech is incomprehensible, it is called jargon aphasia. The patient often appears unaware of his deficit. Synonym: fluent aphasia, impressive aphasia, posterior aphasia, psychosensory aphasia, receptive aphasia, Wernicke's aphasia. (05 Mar 2000) |

| sensory areas | The outer portion of the brain, consisting of layersof nerve cells and the pathways that connect them. The cerebralcortex is the part of the brain in which thought processes take place.In Alzheimer's disease, nerve cells in the cerebral cortex die. (22 May 1997) |
| sensory ataxia | An ataxia due to impairment of position sense caused by lesions located at some point along the central or peripheral sensory pathways. (05 Mar 2000) |
| sensory cell | A cell in the peripheral nervous system that receives afferent (sensory) input; sensory receptor cells. (05 Mar 2000) |
| sensory cortex | Formerly denoting specifically the somatic sensory cortex, but now used to refer collectively to the somatic sensory, auditory, visual, and olfactory regions of the cerebral cortex. (05 Mar 2000) |
| sensory crossway | The postlenticular portion of the posterior limb of the internal capsule of the brain. (05 Mar 2000) |
| sensory decussation of medulla oblongata | The intercrossing of the fibres of the left and right medial lemniscus ascending from the gracile and cuneate nuclei, immediately rostral to the level of the decussation of the pyramidal tracts in the medulla oblongata. Synonym: decussatio lemniscorum, decussatio sensoria, decussation of the fillet, sensory decussation of medulla oblongata. (05 Mar 2000) |
| sensory deprivation | The absence or restriction of the usual external sensory stimuli to which the individual responds. (12 Dec 1998) |
| sensory ganglion | A cluster of primary sensory neurons forming a usually visible swelling in the course of a peripheral nerve or its dorsal root; such nerve cells establish the sole afferent neural connection between the sensory periphery (skin, mucous membranes of the oral and nasal cavities, muscle tissue, tendons, joint capsules, special sense organs, blood vessel walls, tissues of the internal organs) and the central nervous system; they are the cells of origin of all sensory fibres of the peripheral nervous system. (05 Mar 2000) |
| sensory image | An image based on one or more types of sensation. (05 Mar 2000) |
| sensory nerve | <anatomy, nerve> An afferent nerve conveying impulses that are processed by the central nervous system so as to become part of the organism's perception of self and its environment. (05 Mar 2000) |
| sensory neuron | 1. <anatomy> A neuron that receives input from sensory cells. 2. <physiology> Sensory cells such as cutaneous mechanoreceptors and muscle receptors. (18 Nov 1997) |
| sensory neuronopathy | Neuronopathy confined to dorsal root and gasserian ganglia. (05 Mar 2000) |
| sensory nuclei | A group of cell bodies that receive afferent (sensory) input from the periphery. (05 Mar 2000) |
| sensory paralysis | Loss of sensation; anaesthesia. (05 Mar 2000) |
