| Title: | Brain networks underlying haptic texture perception and its illusion |
| Abstract: | Humans are adept at extracting information on material properties of objects by touch. Although there has been growing interest in tactile functions in engineering research, its underlying mechanisms are still poorly understood. I have been conducting functional MRI studies on haptic object perception. In this talk, I will introduce my previous findings that (1) common brain regions (the secondary somatosensory cortex and insula) are involved in processing of roughness and compliance; (2) by contrast, the primary somatosensory cortex is involved in tactile awareness of texture; (3) though it is suggested that visual cortex is involved in tactile texture perception, its role in tactile awareness is limited. I will compare these findings with the current framework on the mechanisms underlying tactile texture perception. |
