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