What's the difference between tactile and tractile?

Tactile

Definition:

(a.) Of or pertaining to the organs, or the sense, of touch; perceiving, or perceptible, by the touch; capable of being touched; as, tactile corpuscles; tactile sensations.

Example Sentences:

(1) Tactile stimulation of a coin-sized area in a T-2 dermatome consistently triggered a lancinating pain in the ipsilateral C-8 dermatome in a 38-year-old woman.
(2) Study I findings did not provide support for synergistic mechanisms; nonorthogonal analysis of variance showed interaction effects (CRT x IT) restricted to tactile-perceptual speed.
(3) For tactile modalities, a lesion of the spinothalamic complex causes minimal or no defects and a lesion of the posterior columns causes only slight defects, whereas a lesion of both pathways gives rise to total loss of tactile and pressure sensibility in the part of the body served by both pathways.
(4) More importantly, motor and cardiovascular responses to startle may be separated through discrimination of afferent stimuli suggesting either differences in neural pathways for acoustic and tactile stimuli or a differential dependency of the various responses on stimulus characteristics.
(5) Animals were trained to perform an orientation match-to-sample task using either a visual or a tactile orientation sample.
(6) Simple screening tests for visual and tactile inattention were used to investigate the influence of perceptual deficits on predictions for the outcome of acute stroke.
(7) The position of the visual receptive field of these neurons did not change after saccadic eyes displacements, but remained in-register with the tactile receptive field.
(8) Complete transection of the thoracic spinal cord eliminated both thermally elicited responses and orienting responses to noxious and tactile mechanical stimulation of the hindlimbs.
(9) The similarity between type III cells and Merkel cells (cells of the tactile system) was surprising.
(10) The level of the DA metabolite 3,4-dihydroxyphenylacetic acid (DOPAC) increases only in pups receiving both odor and tactile stimulation and peaks at about 200% of baseline.
(11) IR is considered to be caused by a group of neurons in the brain stem which inhibit spinal motoneurons, either directly or indirectly, when those inhibitory neurons are activated by a specific pattern of tactile and proprioceptive input.
(12) Although they may occur spontaneously, they are commonly precipitated by tactile stimulation or movement of the extremity.
(13) The oscillatory activity was not affected by anesthesia, but it was often reduced by tactile stimulation or self-initiated movements.
(14) Detection of estrus in mares is problematic in that it requires the presence (or at least facsimile acoustic or tactile stimuli) or a stallion.
(15) The usefulness of tactile devices as aids to lipreading has been established.
(16) Tactile stimuli were applied to the right index fingertip at intervals ranging from 63 to 1,000 msec after the completion of rapid thumb movement.
(17) We previously reported a modality-specific layering of leg sensory axons in the CNS of the flies Phormia regina and Drosophila melanogaster with tactile and gustatory axons projecting into a ventral layer and the proprioceptive hair plate axons into an intermediate layer.
(18) Profound inhibitions of the second phase were also produced by tactile segmental stimulation and noxious stimuli applied to widespread areas of the body (diffuse noxious inhibitory controls).
(19) The apparatus is easily constructed, easily operated, and markedly increases the control of variables in tactile form perception experiments.
(20) Double burst stimulation (DBS) is a new nerve stimulation pattern introduced to facilitate tactile evaluation of recovery from neuromuscular blockade.
