Everything that the insula seems to be involved in  seems to revolve around the activities that young newborn or very young child need to express.

I think that the seat of cognition for a child is the Insula.I think it partners with the Anterior Cingulate gyrus and we get executive locus around the insula rather than say the Pre-frontal cortex.

It stops a child from overeating ( awareness of gastric distention)….allows hand and mouth co-ordination on the level of sophistication that a child needs rather then waiting for the full development of the motor cortex and the 3d precuneus world view .

I believe that under hypnosis ….the 5 year child AC cortex and insula axis of control is  tapped into by an authority figure ( the hypnotist) and they re-institute the power pathway that existed between the parent-child ..that conducted the power relationship through that pathway.

Hence the insula has a residual negativity from that era. The body and the self awareness of it is a large part of the sensory input of a child…unlike an adult who lives in a highly modualted ‘outer ‘ life that does’nt focus so acutely inwardly like a childs life does.
