Comparison of pallial structures among three amniotes. The pallial subdivisions of the mouse (A), chicken (B), and turtle (C) are drawn based on their cytological characteristics. The mouse neocortex and its corresponding pallial regions in the chicken and turtle are colored in pink. The distinctive dense cellular layer in the turtle pallium is indicated by the thick dark-gray line. The right panel in (A) represents expression patterns of layer-specific transcription factor genes in the mammalian neocortex. Colored vertical bars indicate the layers in which each layer-specific marker gene is expressed. Abbreviations: APH, parahippocampal region; DC, dorsal cortex; DVR, dorsal ventricular ridge; H, hyperpallium; hp, hippocampus; M, mesopallium; N, nidopallium; Ncx, neocortex; PC, piriform cortex; PT, pallial thickening; se, septum; st, striatum.
