Table 4.

Cerebral regions whose activity for the contrast [Control > Fixation] was elicited by between-group analyses (total intracranial volume was included as a covariate).

Group analyses [Control > Fixation]		H	BA	k	x	y	z	t	ES [95% CI]
[Young > Older]	No significant activation
[Older > Young]	Superior Frontal Gyrus	L	-	30	−27	32	56	5.56	3.18 [2.06, 4.30]
	[Middle Frontal Gyrus]		8		−36	23	56	4.58	2.44 [1.39, 3.48]

The statistical threshold was defined as p < 0.05 FWE-corrected for multiple comparisons at cluster-level with an extent voxel threshold set at 10 voxels. For each cluster, the region with the maximum t-value is listed first and other regions in the cluster are listed [in square brackets]. Montreal Neurological Institute (MNI) coordinates (x, y, z) of the peak and number of voxels (k) of clusters are also shown. H, hemisphere; R, right hemisphere; L, left hemisphere; BA, Brodmann area; ES, effect size; CI, confidence interval.
