The spectrum of autism encompasses High Functioning Autism (HFA) and Low (LFA). Brain mapping studies have revealed that individuals overlaps in brain behavioural characteristics. Generally, high functioning are known to exhibit higher intelligence better language processing abilities. However, specific mechanisms associated with their functional capabilities still under research.This work addresses the overlapping phenomenon present through connectivity patterns along parameters...
