The density of labelled fibers in the agranular insular cortex was most pronounced in layer I (Fig. 3A,B). Most PHA-L containing fibers within this region were largely short, demonstrated boutons along their lengths and were radially oriented. Labelled fibers in layer I tended to be of a thicker caliber than the smaller numbers of scattered fibers present in the deeper layers of the insular cortex. Collator note: the terminal fields extend in all divisions of the AI (Figs 3 A, B, which correspond to Atlas Leves 13-14 and 17-18, respectively). We consider here 2 separate entries for each AI region: one for the general region, and one for layer I.
