Abstract(in Japanese) (See Japanese page)
Abstract(in English) Anterior Insula is one of the areas for aphasia.. Ventral part of anterior Insula (ProS) has a similar histological structure with temporal pole, and the area for sensory integration by coritco-cortical projection, except visual and olfactory modality. This area has bilateral connection with caudo-ventral part of frontal operculum (ProM), which are supposed to be a supplementary motor cortex for laryngeal and mouth movement. This connection between ProS and ProM may explain reason for mixed type aphasia by Insular infarction. In macaque brain, ProS and ProM has direct connection between them, and both of them has connection with the cortical area, which are analogue for human Broca area. These cortical connection may be the basis for neuronal network to explain motor theory of speech perception, in which, sensory system uses template in motor system while speech perception, or speech perception involves motor system. ProS may be also related with emotion, which is a drive for vocalization, and plasticity, which is one of basic character of language. development
