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.
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 ...
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 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 ...
Tactile stimulation is used in clinical psychology through the method of prompting. Prompting is the use of a set of instructions designed to guide a participant through learning a behavior. A physical prompt involves stimulation in the form of physically guided behavior in the appropriate situation and environment.
There are strong interactions between visual and auditory stimuli. Since both auditory and visual cues provide an accurate source of information about the location of an object, most times there will be minimal discrepancy between the two. However, it is possible to have a disparity in the information provided by the two sets of cues.
The visual system and the somatosensory system are active even during resting state fMRI Activation and response in the sensory nervous system. The sensory nervous system is a part of the nervous system responsible for processing sensory information.
