FIGURE 6

(A) Cytoarchitectonics and morphology of neurons in different forebrain nuclei of neonatal Tt and juvenile Sc. Gray matter nuclei are indicated in Times New Roman font (A–D), as in Figures 4 and 5. CC, corpus callosum; IC, internal capsule; LV, lateral ventricle; wgm, subcortical white matter intermixed with gray matter; Cx, cerebral cortex. Scale bar, 10 μm. (B) Histological analyses carried out on the adult (Tt and Sc) dolphin forebrain. The same forebrain nuclei (A–C) described in neonatal and juvenile dolphin brain can easily be identified in the adult forebrain of both species; abbreviations as in (A). Scale bars: lower magnifications and GFAP staining, 100 μm; higher magnifications, 10 μm. (C) Table summarizing the main histological, morphological and quantitative measure parameters analyzed in the neonatal, juvenile, adult dolphin forebrain, leading to nuclei identification (also based on data reported in Figures 4 and 5); right, quantitative analyses of cell density and neuronal size in three forebrain nuclei at different ages.
