Results of primary analyses of mPFC channels in Experiment 2

Channel	Region	MNI	χ2	pN
7	Superior medial frontal	−11 63 8	0.92	0.554
8	Superior frontal	−16 64 7	2.49	0.197
9	Superior medial frontal	−14 52 4	1.39	0.454
10	Middle frontal	−25 65 7	3.21	0.142

MNI coordinates represent estimated locus of peak sensitivity. χ² statistic results from likelihood ratio tests between full model and reduced model with only random effects during the a priori time window of interest. p_N are p-values from permutation tests (α = 0.0125). It is important to note that the actual cortical sources for each channel are likely more medial in the infant brain compared with the estimates derived from a mature brain model here.
