Sensory
Definition:
(a.) Of or pertaining to the sensorium or sensation; as, sensory impulses; -- especially applied to those nerves and nerve fibers which convey to a nerve center impulses resulting in sensation; also sometimes loosely employed in the sense of afferent, to indicate nerve fibers which convey impressions of any kind to a nerve center.
Example Sentences:
(1) Symptomatic improvement was obtained in 14 of the 15 hands, and sensory-evoked response improved in 13 hands.
(2) The earliest degenerative changes were seen in sensory and motor terminals at 20-24 h after the lesion.
(3) We assumed that the sensory messages received at a given level are transformed by a stochastic process, called Alopex, in a way which maximizes responses in central feature analyzers.
(4) These later results suggest that dopamine agonists increase sensorimotor reactivity measured with acoustic startle by acting on sensory rather than motor parts of the reflex arc.

(8) These results suggest that, to fully understand how multijoint movement sequences are controlled by the nervous system, sensory mechanisms must be considered in addition to central mechanisms.
(9) The peptide selectively inhibits certain postsynaptic cells but not others and thereby allows the sensory neurons to achieve target-specific synaptic actions.
(10) This contrasts sharply with the reduction in both the frequency and surface area of sensory neuron active zones that accompanies long-term habituation, and suggests that modulation of active zone number and size may be an anatomical correlate that lies in the long-term domain.
(11) We report that kainic acid lesions of the posterior corpus striatum, which preferentially spare fibers of passage while destroying striatopallidal neurons, produce a stimulus-sensitive movement pattern in rats that has a highly specific sensory trigger.
