Brain connectivity and high functioning autism: A promising path of research that needs refined models, methodological convergence, and stronger behavioral links

► There are abnormalities in brain-connectivity in people with ASD. ► MRI research generally shows under-connectivity of long-range connections. ► fMRI research on local connectivity shows both over- and under-connectivity. ► EEG and MEG studies on brain-connectivity in ASD provide divergent findings. ► The dominant theory about brain connectivity in ASD should be refined.
