First author (study year)	Toxicant	N	Age at toxicant measure	Toxicant measure	Age at MRI	MRI measure	Exposure main effect
De Water, Curtin et al. (2019)	PBDE	34	Prenatal	Blood sample	5 years	Whole brain GE, LE	Greater PBDE associated with increased GE in regions associated with learning and visual attention and reduced GE in regions associated with visual, auditory, and sensorimotor processing.
Margolis et al. (2020)	PBDE	33	Prenatal	Blood sample	5 years	GE of reading network	Greater PBDE associated with lower GE in the reading network. PBDE-47 and 153 contributed most to this association.
