Functional magnetic resonance brain imaging studies comparing maltreated to non-maltreated individuals.

Studies	ED	Mean age years	Sample	Task	Summary of results
Maheu et al. (2010)	Yes	13.6	11 M vs. 19 NM	FP	M > NM, left amygdala in response to fearful and angry faces, right amygdala: n.s.
Tottenham et al. (2011)	Yes	10.1	22 M vs.22 NM	FP	M > NM, in left and right amygdala in response to fearful faces
Carrion et al. (2008)	No	13.5	16 MP vs.16 NM	GNG	M > NM, in left and right ACC when in contrast no-go minus go trials
Mueller et al. (2010)	Yes	13.0	12 M vs. 21 NM	STOP	M > NM, in left and right ACC when contrast correct change minus correct go
Carrion et al. (2010)	No	13.9	16 MP vs. 11 NM	VDM	M < NM, right HIPP activity negatively correlated with symptoms severity, left HIPP: n.s.
Grant et al. (2011)	No	32.8	10 MD vs. 10 M vs. 16 NM	FTF	M > MD = NM, in right amygdala response to sad faces, left amygdala: n.s.
Dillon et al. (2009)	No	30.8	13 M vs. 21 NM	R/L-P	M < NM, blunted brain response to reward cues in the left pallidus
Croy et al. (2010)	No	39.9	12 M vs. 10 NM	OS	M > NM, increased activation in posterior cingulate cortex and decreased activation in subgenual ACC

ACC, anterior cingulate cortex; ED, early deprivation; FP, face processing; FTF, Flanker task with face stimuli; GNG = Go/No-go; M, maltreated; MD, maltreated with depression; MP, maltreated with PTSD/PTSD symptomatology; NM, non-maltreated; R/L-P, reward/loss processing; STOP, stop task; VDM, verbal declarative memory.
