  Abstract

Different sensations are generated when we touch textiles with different performance. The mechanical properties related to fabric touch have been studied for a long time, the relationship between which and the subjective feelings is well understood. However, the cognitive mechanism of our brain on the tactile perception evoked by fabric touch were rarely studied. The relationship between mechanical properties of fabrics and the brain response in different areas is the vacancy of the study but urgent problem. In our previous study, the advanced technology of fMRI was proved to be an effective tool for detecting brain response evoked by tactile stimulation of fabric touch with high spatial resolution. Now in this study, further fMRI experiments were conducted to observe brain response when participants touched different fabrics using their fingers in a specified way, and the most widely recognized functional atlas, Brodmann셲 area maps, were applied to locate the cortical activations in functional areas. Activations in the participants셲 brain in different Brodmann areas was compared with the mechanical preperties of the fabric samples tested by the instruments of KES-FB. The results showed that activation information in the participants brain can distinguish the fabric samples very well. Activations in several Brodmann areas are closely connected with different tactile preperties of the fabrics. Therefore, Brodmann셲 area maps were proved to be a useful functional atlas for cortical localization of tactile perception evoked by fabric touch.
