Trying to Put the Puzzle Together: Age and Performance Level Modulate the Neural Response to Increasing Task Load within Left Rostral Prefrontal Cortex

Table 5

Localization and statistics of the peak voxels for the group load interaction (ROI analyses).

PFC; subregion	ROI	Brain structure	x	y	z	F
DLPFC	BA 46	L frontal inferior gyrus, triangular part		23	25	4.48	0.030
VLPFC	BA 44	L frontal inferior gyrus, opercular part		17	16	3.91	0.039
	BA 45	L insula		20	4	5.10	0.007

Note. Threshold of < 0.05 (FWE-corrected according to SPM8, small volume correction). indicates results surviving a Bonferroni-correction for the set of ROIs ( < 0.005). All coordinates () are given in MNI space. PFC = prefrontal cortex; DLPFC = dorsolateral prefrontal cortex; VLPFC = ventrolateral prefrontal cortex; ROI = region of interest; BA = Brodmann area; L = left; R = right.
