One of the 21 models constituting the model space, in this case with the modulatory effect between visual cortex and orbitofrontal cortex (OFC) for both forward and backward direction. The connections considered are backed up by previous anatomic studies, as indicated by the numbers1,30,31 2–4,32 5,33 6,34 729 and 8.29,35 DS/Put = dorsal striatum/putamen; Ins = insula; l = left; r = right; V1 = visual cortex; vmPFC = ventromedial prefrontal cortex.
