Figure 2. Comparison of right BA 9 peak activations across studies.

Figure 2

(a) Reverse-inference analysis of the term “task difficulty” in NeuroSynth revealed a right BA 9 cluster (MNI 42, 6, 32, z = 7.22) spanning middle/inferior frontal gyrus at p < .01, False Discovery Rate corrected. A cluster threshold of 150 voxels was applied for display purposes to highlight the right lateral prefrontal cortex activation. ROIs are displayed on an SPM template average of 152 normalized T1 anatomical scans. (b) Regions of interest (8 mm spheres) were drawn to surround the peak activation in right BA 9 for the present study (MNI 46, 2, 30), Demeter et al. (2011) (MNI 35, 9, 33), and Kim et al. (2006) (MNI 45, 21, 33). Though the imaging modality (BOLD vs ASL) and design (block vs event-related) varied across study, the findings generally converge to suggest a role of right BA 9 (specifically IFG/MFG) in controlled attention under challenging conditions.
