Fig. 3. MRgFUS targeting of the ventral ALIC.
A Schematic displaying the overlap of executive and limbic circuit axonal fibers in the ALIC. Fibers projecting from the orbitofrontal cortex (blue) and cingulate cortex (green) are found more ventrally within the ALIC, and are associated with the limbic circuit. Fibers projecting from the dorsolateral prefrontal cortex (red), are found more dorsally in the ALIC, and are associated with the executive circuit. As demonstrated in the yellow inset box, larger lesions (lesions indicated by dotted white lines) interrupt a greater proportion of limbic fibers, but also impinge on the executive circuit. Y coordinates indicate the anterior–posterior position of each slice in Montreal Neurological Institute (MNI) space. Regions are drawn for illustrative purposes and are not to scale. b Coronal representation of lesion centroids in MNI-space, coded for clinical responders (light blue), and non-responders (red).
