Dear experts,
in one experiment we found a right lateral prefrontal activation cluster (MNI coordinates of strongest activated voxel: x=47, y=48, z=-3) which is mainly attributed to Brodmann area 10 (BA 10) if we look at the BA 10 ROI-mask derived from WFU Pickatlas, but lies entirely in BA 46 and BA 47 if we project the activation cluster onto the Brodmann map implemented in MRIcron.
The Talairach Client also attributes voxels from that cluster to BA 10 and BA 46. We are confused about which Brodmann area maps we should “trust” and also about the very fact that they differ so greatly from each other (shouldn’t they all be same?).
I’ve attached two files: the first showing how the BA 10 mask (in bright red) from WFU Pickatlas overlaps with BA 46(in green) and other areas when projected onto the MRIcron Brodmann template; the other displays the position of the activated prefrontal region in our experiment.
Any help on this would be much appreciated,
Christian
