Diagram showing the overlap and relative proportions of neuronal populations containing calcium-binding proteins, neuropeptides, and 5-HT3AR in the anterior subdivision of the basolateral nucleus (BLa). The relationship of the 5-HT3AR+ subpopulation to the other interneuronal subpopulations is similar in the lateral nucleus. Thick lines indicate the 5-HT3AR + subpopulation. Lines of intermediate thickness indicate two populations of calcium-binding proteins (CB+ and CR+ neurons), each of which is comprised of several subpopulations. Data on the relationships among SOM+, PV+, CB+, CR+, VIP, and CCK+ neurons is taken from previous quantitative studies (for a review see Mascagni and McDonald, 2003); the relative sizes of the rectangles representing these subpopulations are depicted in relation to the total population of GABA+ neurons in each nucleus (see Fig. 3 of McDonald and Mascagni, 2002). Note that the 5-HT3AR+ subpopulation is relatively small and slightly overlaps the subpopulation of large type L CCK+ neurons (CCKL) that do not contain CB. In the present study it appeared that none of the 5-HT3AR+ neurons corresponded to the subpopulation of small type S CCK+ neurons (CCKS).
