Expression of select ion channel genes in LMAN and Area X. (a) Camera lucida drawing depicting anterior portions of the nidopallium and medial striatum including song nuclei LMAN and Area X in the parasagittal plane (approximate location is indicated in inset; the pallial-subpallial lamina is depicted by thin line). (b-h) Representative in situ hybridization photomicrographs of select ion channel genes that show differential expression in Area X (all panels except d) and LMAN (b, d, f-h) compared to adjacent regions. Arrow in (d) indicates LMAN and inset shows enhanced labeling in a population of sparse cells from the indicated region of Area X. (i) Camera lucida drawing depicting LMAN and dorsal Area X at same level as in (a). (j-l) Representative in situ hybridization photomicrographs of select ion channel genes that show differential regulation in LMAN compared to the adjacent nidopallium. Note the sparse, darkly stained cells in Area X in panel (j). Gene abbreviations are given in Table 1. Scale bars for each panel series are 500 μm
