Distribution of the high density and overlapping voxels between cholinergic and CB neurons in the medial septum (B–D), the HDB (F–H) and in the ventral pallidum (J–L) from case 96001. Density threshold is five cells and voxel size of 250 × 250 × 50 μm. Red voxels: high density cholinergic, blue: high density CB and white voxels: high-density overlapping voxels. The panels in (A, E, I) in the upper row show all four cell markers in the septum (A), in the HDB (E) and in the ventral pallidum (I). In these panels cholinergic cells are red, CB neurons blue, CR cells yellow and PV cells green.
