Significance of tactile localization
WebLocalization of tactile stimuli to the hand and digits is fundamental to somatosensory perception. However, little is known about the development or genetic bases of this ability … WebIt is a joint project of the Chair for Computer Aided Medical Procedures & Augmented Reality, TUM, and the Chair for Applied Mechanics, TUM. The research topics include environment perception & localization, navigation & motion planning, and stabilization & multi-contact control.

WebOct 6, 2024 · Our sense of touch is controlled by a huge network of nerve endings and touch receptors in the skin known as the somatosensory system. This system is responsible for all the sensations we feel – cold, hot, smooth, rough, pressure, tickle, itch, pain, vibrations, and more. Within the somatosensory system, there are four main types of receptors ... WebOct 19, 2024 · We estimate that the skin across the whole body of young adults is innervated by ∼230,000 tactile afferent fibers (plausible range: 200,000–270,000), with a subsequent decrement of 5–8% every decade due to aging. Fifteen percent of fibers innervate the palmar skin of both hands and 19% the region surrounding the face and lips.
WebDifferent approaches of lateralization in cutaneous perception involved (1) point localization, in which the subject has to report the spatial location of the tactile stimulus, (2) the two-point discrimination technique, in which the experimenter measures the minimal separation required to perceive the two points as being discriminable, and (3) the discrimination of … WebWeber's two-point discrimination test is the most common method used to of assess sensibility of the upper extremity. The amount of force applied between one and two points easily exceeds the resolution or sensitivity threshold for normal sensation. Tremendous variance in pressures applied resulted in poor levels of interrater reliability.
WebAug 22, 2005 · Notably, we found that cortical processing for tactile localization was right-hemisphere dominant, independent of the side of stimulation, in a region that commonly produces neglect when damaged . In this context, it is interesting that Naito et al.
