AB - Fabric, our second skin with moisture and thermal capacity for skin  temperature regulation, can arouse feelings of pleasant and discomfort. To  examine the neurocognitive ability and emotion of fabric tactile perception  under different local temperatures, we used functional magnetic resonance  imaging with the same denim fabric stimuli and forearm contact area, and  found a functional dissociation: the affective regions was more involved  during warm condition, the discriminative regions were more involved during  neutral condition and the basis regions were significance during cool  condition. The higher local skin temperature environment can result in the  improvement of sensitivity and discriminability by dorsal pathway (spatial)  and ventral pathway (frequency) for fabric perception. Our results help to  explain how the brain uses internal models to interpret external fabric  tactile stimuli with micro environmental changing.
