Selected Studies Related to Functional Connectivity for an Overview of Relevant Advances in the Field

Paper	Number of Subjects (Those with ASD)	Control	Environment	Analysis	ASD Changes
Orekhova et al16	N=28; 18 females and 10 males	N/A	Video stimuli	Weighted phase lag index	It was found that there is hyper-connectivity in frontal and central areas
Righi et al17	N=Unspecified	N/A	Speech and Sound	Coherence analysis	Higher risk for people
Murias et al12	N=18	N=18 males	Eyes closed and relaxed	Coherence analysis	Increased frontal and temporal hemisphere and decreased frontal area
Boersma et al15	N=12; mean age 3.5 years	N=19	Using car pictures	Clustering analysis	The whole-brain activity was affected
Catarino et al13	N=15	N=15	Recognizing objects	Coherence analysis	Decreased coherence
Carson et al14	N=19	N=13 typically developing children; 9 males and 4 females	Videos of people reading a story	Coherence analysis	Decreased frontal and temporal lobes
Cantor et al18	N=11	N=88; Normal children but intellectually disabled N=18; Mentally handicapped children N=13; Mentally age-matched normal toddlers	Eyes open and relaxed	Coherence analysis	Increased coherence in delta and alpha band
Buckley et al19	N=87	N=21; Developmental delay without autism. N=29; typical development	Awake or in Low Sleep	Coherence analysis	Increased frontal coherence
