The tactile image is then projected onto the tongue via the ribbon cable where the tongue's receptors pick up the signal. After training, subjects are able to associate certain types of stimuli to certain types of visual images. [7] [41] In this way, tactile sensation can be used for visual perception.
Tactile extinction, as an example, can be modulated by visual events simultaneously presented in the region near the tactile stimulation, increasing or reducing tactile perception, depending upon the spatial arrangement of the stimuli. [12] In one example of visual and tactile relationship, the visual stimulation in the ipsilesional side ...
The visual system is very static, in that it does not move around much, but the hands and other parts used in tactile sensory collection can freely move around. This movement of the hands must be included in the mapping of both the tactile and visual sensations, otherwise one would not be able to comprehend where they were moving their hands ...
This photo shows tactile markings identifying stairs for visually impaired people. The somatosensory system , or somatic sensory system is a subset of the sensory nervous system . It has two subdivisions, one for the detection of mechanosensory information related to touch, and the other for the nociception detection of pain and temperature. [ 1 ]
RT to simultaneous visual and tactile stimuli was also faster than RT to simultaneous dual visual or tactile stimuli. The advantage for RT to combined visual-tactile stimuli over RT to the other types of stimulation could be accounted for by intersensory neural facilitation rather than by probability summation. These effects can be ascribed to ...
Tactile defensiveness: negative reaction to tactile stimuli; Visual perceptual deficits: poor form and space perception and visual motor functions; Somatodyspraxia: poor motor planning (related to poor information coming from the tactile and proprioceptive systems) Auditory-language problems
Chemical stimuli, such as odorants, are received by cellular receptors that are often coupled to ion channels responsible for chemotransduction. Such is the case in olfactory cells . [ 12 ] Depolarization in these cells result from opening of non-selective cation channels upon binding of the odorant to the specific receptor.
The tau effect can occur with visual, [3] [4] auditory, [5] or tactile stimuli. [1] In touch, the tau effect was first described by Gelb (1914). [ 6 ] It was later given its name by Helson (1930) [ 7 ] and characterized in detail by Helson and King (1931). [ 1 ]
