From: Morphogenesis underlying the development of the everted teleost telencephalon
Conventional model for eversion in ray-finned fishes. Cartoon showing the classic view for eversion in ray-finned fishes (left) in contrast with the evagination of the telencephalic vesicles that occurs in other vertebrates (right). In ray-finned fishes, it is thought that the dorsal region of the telencephalic neural tube (pallium) folds over the ventral region (subpallium), stretching the dorsal roof-plate region of the neural tube (green) to form the tela choroidea. This would also relocate some ventricular cells to the dorsal telencephalic surface (red dotted line) and cause medial to lateral rearrangements of pallial regions (compare the location of regions A, B, and C between everted and evaginated telencephali). Modified from [16]. rp, roof plate, sp, subpallium, tc, tela choroidea, v, ventricle.
