Structural connectivity maps of the thalami: processing pipeline and output.. Overview of the principal processing steps used to create maps of structural connectivity between the different portions of the thalami and a selection of Brodmann areas (BAs) in the prefrontal cortex. Panel A shows the seed areas (resulting from binarizing the Oxford thalamic atlas available with FSL) used for tractography. Panel B illustrates the selection of prefrontal areas used as target points in probabilistic tractography. Panel C shows the segmentation of the thalamus in sub-regions as a function of their maximum connection probability with a given prefrontal area, before applying the minimum probability threshold. Panel D shows the map of maximum connection probability of each voxel of the thalamus with the prefrontal cortex and the threshold used to retain the highest probability connections. Panel E shows the resulting segmentation after applying the minimum probability threshold of 0.5. See text for further details.

According to the aim of the current study, the following prefrontal areas were considered: BA6, BA8, BA9, BA10, BA32, BA44, BA46 (Figure 1).
