Gene markers showing regional and laminar specificities of field CA1 pyramidal neurons. For high-resolution Nissl-stained cytoarchitecture and delineation of pyramidal neuron sublayers, see Fig. 1 and Fig. S1. CA1v subdomains are labeled: a (CA1vd), b (CA1vid), c (CA1viv), and d (CA1vv). All digital images were downloaded from the ABA gene expression library. (Gene names and the image series numbers of their original digital images are listed in Table S1.) Images in the same rows have the same magnifications.
