“…However the different immunostaining allows (in most cases) clear distinction between prethalamus (p3), thalamus (p2), and pretectum (p1), as well as subdivisions within them, that respect and are well explained by the prosomeric model [Pombal and Puelles, 1999;Dávila et al, 2000;Milán and Puelles, 2000;Castro et al, 2006;Morona and González, 2008]. A main trait of the distribution of these proteins in the diencephalon is the abundant presence of CR in thalamic neurons in anamniotes [present results;Pombal and Puelles, 1999;Díaz-Regueira and Anadón, 2000;Milán and Puelles, 2000;Castro et al, 2006], whereas in amniotes CB prevails in the thalamus [Braun, 1990;Pritz and Stritzel, 1991;Pritz and Siadati, 1999;Dávila et al, 2000;Münkle et al, 2000;. Within the alar part of p1, the distribution of CB and CR in Dermophis seemed to match well with the 3 molecularly distinct anteroposterior domains already recognized in several vertebrate groups [Pombal and Puelles, 1999;Dávila et al, 2000;Milán and Puelles, 2000;Ferrán et al, 2007;Morona et al, 2011].…”
