Table 3

Regions with functional activation that were correlated with performing the task in the scanner (main effect): positive associations are listed first and negative associations are listed next.

Regions	Cluster size	Peak T-Score	Montreal Neurological Institute coordinate for Peak T-Score
Regions with activation positively correlated with main effect
Superior parietal lobe, bilaterally	6912	12	−28, −62, 52^1
Left middle frontal gyrus	3529	12	−44, 2, 34^2
Right middle frontal gyrus	3133	8.5	36, 2, 52^3
Medial frontal gyrus, bilaterally	1196	8.6	2, 20, 46^4
Right inferior frontal gyrus	375	6.3	34, 24, −5^5
Right thalamus	214	4	18, −6, 19
Left thalamus	212	4.1	−16, −12, 16
Regions with activation negatively correlated with main effect
Left superior temporal gyrus	1285	−6.6	−66, −22, 1
Right superior temporal gyrus	891	−5	56, −30, 22
Posterior cingulate cortex, bilaterally	821	−6.1	−4, −52, 28

This table reports the spatial distribution of the mean group activation (obtained from the DSST > control condition contrast and from the control condition > DSST contrast), including the size of cluster, the maximum statistic for the cluster, and the location of the maximum statistic in Montreal Neurological Institute coordinates. The corrected alpha is the probability of false positive detection based on the combination of individual voxel probability thresholding and minimum cluster size thresholding.
¹This cluster extends medially to include the precuneus and caudally to include the superior occipital gyrus; it includes the most dorsal part of the inferior parietal lobule.
²This cluster extends rostrally to include the supplementary motor area, caudally to include the precentral gyrus, and medially to include the insula.
³This cluster extends rostrally to include the supplementary motor area, caudally to include the precentral gyrus, and ventrally to include the inferior frontal gyrus.
⁴This cluster extends caudally in the right hemisphere to include the dorsal cingulate cortex.
⁵This cluster covers part of the insula.
