“…A third, but less acknowledged, hypothesis is that the different subdivisions of the anterior DVR as a field are homologous to both cortical and claustrum/amygdala cell types Molnar and Butler, 2002). To address these hypotheses, a number of elegant comparative and manipulation experiments have since been performed, but still with continued conflicting conclusions Medina and Abellan, 2009;Nomura et al, 2009;Uchida et al, 2010;Wang et al, 2010; Aboitiz, 2011;Butler et al, 2011;Kuenzel et al, 2011;Medina et al, 2011;Puelles, 2011;Tanaka et al, 2011;Atoji and Karim 2012;Dugas-Ford et al, 2012;Suzuki et al, 2012).Resolving these hypotheses, we believe, is in part hampered by yet another set of unanswered questions on our still limited understanding of overall avian brain organization.To address this issue, here we quantitatively analyzed telencephalic expression profiles of 46 constitutive and 6 activity-responsive genes (52 total; (Kubikova et al, 2010), the SEMA6A axon guidance receptor , cannabinoid receptor (Soderstrom et al, 2004), and retinoic acid orphan related receptor beta (ROR-β; this study); the NRN, BDNF, and SCUBE1 protein ligands (Wada et al, 2006;Lovell et al, 2008); the DLX6 (this study), FOXP1, FOXP2, ER81, COUP-TF2, LHX8, LHX9, NKX2.1, PAX6, EGR1, C-FOS, and C-JUN transcriptions factors (Jarvis and Nottebohm, 1997;Kimpo and Doupe, 1997;Haesler et al, 2004;Jarvis et al, 2005;Abellan et al, 2009); the FKBP1A (this study), DUSP1 (a.k.a. map kinase phosphatase 1 [mkp1]), and PPAPDC1A enzymes Horita et al, 2010Horita et al, , 2012; and a diverse set of membrane and cytoplasmic genes, including ARPP16 (this study), TMEM100 (this study), ARC, CADPS2, and S100B (Wada et al, 2006;Lovell et al, 2008) (Table 1).…”

The last two authors contributed equally in co-supervising the project and conducting experiments. The second and last authors began this project originally as part of their graduate theses. ROLE OF AUTHORSEDJ, CCC, and KW performed experiments, quantifications, analyses, and wrote the article; JY, AP, CCC performed the computational analyses; MVR, HH, GF, OW, SCJ, ERJ, LK, SB, and ME performed gene expression experiments. SCJ also generated the 3D images and movies. AEPP processed and quantified images. CS and EH processed tissues and performed cell density measurements. HM helped co-supervise experiments.Additional Supporting Information may be found in the online version of this article.

The patterns of constitutively expressed genes revealed a partial mirror image organization of three major cell populations that wrap above, around, and below the ventricle and adjacent lamina through the mesopallium. The patterns of behaviorally regulated genes revealed functional columns of activation across boundaries of these cell populations, reminiscent of columns through layers of the mammalian cortex. The avian functionally regulated columns were of two types: those above the ventricle and associated mesopallial lamina, formed by our revised dorsal mesopallium, hyperpallium, and intercalated hyperpallium; and those below the ventricle, formed by our revised ventral mesopallium, nidopallium, and intercalated nidopallium. Based on these findings and known connectivity, we propose that the avian pallium has four major cell populations similar to those in mammalian cortex and some parts of the amygdala: 1) a primary sensory input population (intercalated pallium); 2) a secondary intrapallial population (nidopallium/hyperpallium); 3) a tertiary intrapallial population (mesopallium); and 4) a quaternary output population (the arcopallium). Each population contributes portions to columns that control different sensory or motor systems. We suggest that this organization of cell groups forms by expansion of contiguous developmental cell domains that wrap around the lateral ventricle and its extension through the middle of the mesopallium. We believe that the position of the lateral ventricle and its associated mesopallium lamina has resulted in a conceptual barrier to recognizing related cell groups across its border, thereby confounding our understanding of homologies with mammals.

“…Ependymal cells in the H, M, and N may be similar to those of the mammalian cortex. At the point of the ependyma, the H, M, and N may be considered as the pallium, although these regions were subdivided by glial developmental distribution [27]. The ependyma of the BG was thick and consisted of Vim [24].…”

“…In our previous study, we observed long Vim + processes on the LFS, and LPS from embryo to young. Moreover, these long processes were the bounder of the compartment of the chicken Tc and continued into the OB [27]. In adult mammals, the root named rostral migratory stream (RMS) run from LV to OB, and the base of the RMS in mammals is the boundary between the BG and white matter [7,8].…”

ABSTRACT. The constitution of ependyma derived from the ventricular zone is different from that derived from other regions of the central nervous system. In the mammalian cerebrum, the ependyma is varied by the regions to cortex or basal ganglia (BG). In the avian telencephalon (Tc), previous studies about the constitution of the ependyma have not revealed clear findings. In the present study, we performed immunostaining of ependymal cells in the chicken Tc to confirm differences in the ependyma of various regions. As a result, 4 patterns of ependyma were defined in the outer side of the lateral ventricle. In the base of the lamina pallio-subpallialis (LPS), ependyma consisted of vimentin/glial fibrillary acidic protein (GFAP) double-positive cells, whereas in the base of the lamina frontalis superior, it consisted primarily of vimentin-positive cells and a small number of vimentin/GFAP double-positive cells. With the exception of the above, the pallial ependyma was a single layer containing vimentin single-positive cells. Lastly, the ependyma of the BG was rich in vimentin single-positive cells. The constitutional differences of the ependyma of the pallium and BG concerned differences in ependymal morphology and cell characteristics. These finding suggest that the bounder between pallium and BG is LPS at the point of ependyma.
