Outline of Final Research Achievements

fNIRS studies presented followings. 1) Brain activities in the somatosensory association cortex and visual cortex were presented during gum chewing. 2) Brain activities in the somatosensory association cortex and the visual cortex were consolidated in accordance with gum hardness and gum size. 3) Brain activities in the somatosensory association cortex and visual cortex were modulated by oral sensory de-afforestation.
Further, fMRI studies presented followings. 1) Brain activities in the bilateral motor cortex, visual cortex, and insula were presented during chewing performance. 2) Brain activities in the premotor cortex, supplementary motor area and visual cortex were presented during chewing imagery. 3) Brain activities in the bilateral motor cortex, visual cortex, and insula were modulated by oral sensory de-afforestation.
From these results, it is concluded that the association between oral somatosensory and visual sensation could be estimated during chewing performance.
