In the current research, diffuse optical imaging (DOI) is used for the first time towards studies related to sociocommunication
impairments, which is a characteristic feature of autism. DOI studies were performed on normal adult
volunteers to determine the differences in the brain activation (cognitive regions) in terms of the changes in the cerebral
blood oxygenation levels in response to joint and non-joint attention based stimulus (i.e. socio-communicative
paradigms shown as video clips). Functional connectivity models are employed to assess the extent of synchronization
between the left and right pre-frontal regions of the brain in response to the above stimuli.
