Neurons, Afferent definition: Neurons which conduct NERVE IMPULSES to the CENTRAL NERVOUS SYSTEM.
Sensory Neuron definition: Neurons which convey sensory information centrally from the periphery. (MeSH)
sensory receptor definition: specialized sensory nerve processes or epithelial structures that respond to specific kinds of stimuli in the internal or external environment; this term refers to cells and cellular structures, as opposed to the molecular and submembrane structures covered by RECEPTOR.
Sensory Receptor Cells definition: Specialized afferent neurons capable of transducing sensory stimuli into NERVE IMPULSES to be transmitted to the CENTRAL NERVOUS SYSTEM. Sometimes sensory receptors for external stimuli are called exteroceptors; for internal stimuli are called interoceptors and proprioceptors.
Sensation definition: The process in which specialized SENSORY RECEPTOR CELLS transduce peripheral stimuli (physical or chemical) into NERVE IMPULSES which are then transmitted to the various sensory centers in the CENTRAL NERVOUS SYSTEM.
sensation definition: transduction of stimuli from outside the body and those within the body into nerve impulses by receptors, and the transmission of these impulses by afferent neurons to the cerebral cortex.
sensory perception definition: The series of events required for an organism to receive a sensory stimulus, convert it to a molecular signal, and recognize and characterize the signal. [GOC:ai, GOC:dph]
Sensory Deprivation definition: The absence or restriction of the usual external sensory stimuli to which the individual responds.
sensory deprivation definition: the absence or restriction of the usual external sensory stimuli to which the individual responds.
sensory neuropathy definition: functional disturbance or pathological change in the peripheral nervous system; sometimes limited to noninflammatory lesions as opposed to those of neuritis; etiology may be known or unknown.
Peripheral Sensory Neuropathy definition: Inflammation or degeneration of the sensory nerves. - 2003
sensory disorder definition: disorders of the special senses (ie, vision, hearing, taste and smell) or somatosensory system (ie, afferent components of the peripheral nervous system).
sensory feedback definition: a mechanism of communication within the sensory system in that the input signal generates an output response which returns to influence the continued activity or productivity of the sensory system.
visual feedback definition: return of some of the output of the visual system as input to exert some control in the process.
Feedback, Sensory definition: A mechanism of communicating one's own sensory system information about a task, movement, skill, etc.
SENSORY COMPONENT definition: Cluster of elements that involve the senses including pain.
Ganglia, Sensory definition: Clusters of neurons in the somatic peripheral nervous system which contain the cell bodies of sensory nerve axons. Sensory ganglia may also have intrinsic interneurons and non-neuronal supporting cells.
Sensory Ganglion definition: Clusters of neurons in the somatic peripheral nervous system which contain the cell bodies of sensory nerve axons. Sensory ganglia may also have intrinsic interneurons and non-neuronal supporting cells. (MeSH)
Discomfort definition: A feeling of mental or physical uneasiness, pain, or distress.
Sensory Gating definition: The ability of the BRAIN to suppress neuronal responses to external sensory inputs, such as auditory and visual stimuli. Sensory filtering (or gating) allows humans to block out irrelevant, meaningless, or redundant stimuli.
sensory definition: Having to do with the senses.
afferent nerve definition: sensory nerves bringing impulses toward the central nervous system.
Sensory nerve definition: General anatomical term applied to nerves in which somatic afferent nerve fibers predominate.
sensory cortex definition: used to refer collectively to the somatic sensory, auditory, visual, and olfactory regions of the cerebral cortex.
sensory depression definition: induced loss of feeling or sensation, usually using drugs, to permit performance of surgery or other painful procedures.
sensory discrimination definition: ability to notice small differences in sensations.
sensory mechanism definition: fundamental physical or chemical processes involved in or responsible for conveying a stimulus to the sensory nerve center.
Sensory Rhodopsins definition: Photosensory rhodopsins found in microorganisms such as HALOBACTERIA. They convert light signals into biochemical information that regulates certain cellular functions such as flagellar motor activity.
sensory processing definition: Any neural process required for an organism to sense and interpret the dimensions of a sensory experience: modality, location, intensity and affect. [GOC:dph, ISBN:0721662544 "Dorland's Illustrated Medical Dictionary"]
Sensory Process definition: Processes that involve and promote the transfer or transmission of stimulatory (sensory) information from the periphery to more central organized structures and mechanisms involved in processing information. (NCI)
