The somatosensory cortex encodes incoming sensory information from receptors all over the body. Affective touch is a type of sensory information that elicits an emotional reaction and is usually social in nature, such as a physical human touch. This type of information is actually coded differently than other sensory information.
Like other tactile discrimination tests, the test for this is a measurement of the patient's sense of touch, and requires that the patient perform the test voluntarily and without visual contact. The purpose of this form of tactile discrimination is to detect any defects in the Central nervous system such as lesions in the Brainstem , Spinal ...
The wheel was designed to test nerve reactions (sensitivity) as it rolled systematically across the skin. [1] A Wartenberg wheel is generally made of stainless steel with a handle of approximately 18 centimetres (7 in) in length. The wheel, which has evenly spaced radiating sharp pins, rotates as it is rolled across the flesh.
Two-point discrimination (2PD) is the ability to discern that two nearby objects touching the skin are truly two distinct points, not one.It is often tested with two sharp points during a neurological examination [1]: 632 [2]: 71 and is assumed to reflect how finely innervated an area of skin is.
In another study, Iwadate et al. (2005) looked [7] at the relationship between physical exercise and somatosensory processing using SEPs. The study compared SEPs in athletes (soccer players) and non-athletes, using two oddball tasks following separate somatosensory stimulation at the median nerve and at the tibial nerve.
Sensory processing disorder (SPD), formerly known as sensory integration dysfunction, is a condition in which multisensory input is not adequately processed in order to provide appropriate responses to the demands of the environment.

A tactile sensor is a device that measures information arising from physical interaction with its environment. Tactile sensors are generally modeled after the biological sense of cutaneous touch which is capable of detecting stimuli resulting from mechanical stimulation, temperature, and pain (although pain sensing is not common in artificial ...
