| Research Abstract |
We examined the effects of tactile stimulation of kusuguttai, a kind of touch sensation. We found that the blood flow was changed in the human brain regions corresponding to the precentral and postcentral gyurs when the base of the foot was stimulated by a brush. In addition, the tactile stimulation on the back skin of mice using a brush changed the expression of the serotonin receptors in the cerebral cortex and the hippocampus.
