Figure 5.

Distribution of labeled neurons in claustrum following injections in area 12. Heat map projections for two injections of diamidino yellow (DY) in area 12 (cases FR02- left; FR04- right). Line drawings show injection locations in frontal sections. Center schematic image shows location of claustrum relative to tissue sections and major sulci of the Cebus brain (gray silhouette). Red dashed lines correspond to tissue sections as marked. The dotted arrows on the right indicate the approach used for injection of area 12o, which traversed the cortical white matter overlying that area. Implications of this approach for interpretation of the data are described in the text.
