“…Components of Encephalic Arteries Differ between Non-Mammalian Vertebrates and Mammals. Fish, reptiles, and most birds possess a single cervical carotid artery that runs up the neck to the external skull base, where it bifurcates into two ICAs [1,25,31]. In the case of sh, birds (as demonstrated in our results), amphibians, and reptiles, cerebral blood supply originates from paired ICAs, which then divide into cranial and caudal branches near the forebrain.…”

Intracranial arterial vascular anatomy is well known in humans, but it is lacking for most mammalian and non-mammalian model species, especially concerning the origin of the basilar artery (BA).We have studied the encephalic arteries in three different species of birds and eight different species of mammals using formalin-xed brains injected with arterial red latex. Our results and literature analysis indicate that, for all vertebrates, the internal carotid artery (ICA) supplies the brain and divides into two branches: a cranial branch and a caudal branch.The difference between vertebrates lies in the caudal branch of the ICA. For non-mammalian vertebrates, the caudal branch is the origin of the BA, and the vertebral artery (VA) is not involved in brain supply. For mammals, the VA supplies encephalic arteries, but in two different ways. In fact, there are two types of encephalic artery organization.In the rst type of organization, mostly found in ungulates, the carotid rete mirabile supplies the encephalic arteries, the caudal branch is the origin of the BA, and the VA is indirectly involved in carotid rete mirabile blood supply. We believe that the carotid rete mirabile may be the result of occipitocervical biomechanics and climatic adaptations.The second type of encephalic artery organization for mammals is the same as in humans. The caudal branch of the ICA serves as the posterior communicating artery, and the BA originates from both VAs.

“…The two caudal branches merge to form a single midline basilar artery. The VA does not enter the skull and does not supply the brain [1,30,31]. Mammals, on the other hand, exhibit a different pattern of encephalic artery supply, leading to variable origins of the BA.…”

“…According to Nieuwenhuys and Puelles (2016), the rhombencephalon consists of 12 neuromeres (rhombomeres, isthmus or r0 plus r1‐r11) in longitudinal series. In cyprinids like the Goldfish ( Carassius auratus ), the rostral rhombomeres two to six (r2‐r6) correspond to the mammalian pons, whereas the caudal rhombomeres seven to eight (r7‐8) correspond to the mammalian medulla oblongata (Gilland et al., 2014; Rahmat & Gilland, 2019). The rostral rhombomeres r2‐r6 form clearly segmented neural clusters while the caudal r7‐r8 lack a precise morphological delineation (Ma et al., 2009).…”

Bitterlings are carp‐like teleost fish (Cypriniformes: Acheilanathidae) known for their specialized brood parasitic lifestyle. Bitterling embryos, in fact, develop inside the gill chamber of their freshwater mussel hosts. However, little is known about how their parasitic lifestyle affects brain development in comparison to nonparasitic species. Here, we document the development of the brain of the rosy bitterling, Rhodeus ocellatus, at four embryonic stages of 165, 185, 210, 235 hours postfertilization (hpf) using micro‐computed tomography (microCT). Focusing on developmental regionalization and brain ventricular organization, we relate the development of the brain divisions to those described for zebrafish using the prosomeric model as a reference paradigm. Segmentation and three‐dimensional visualization of the ventricular system allowed us to identify changes in the longitudinal brain axis as a result of cephalic flexure during development. The results show that during early embryonic and larval development, histological differentiation, tissue boundaries, periventricular proliferation zones, and ventricular spaces are all detectable by microCT. The results of this study visualized with differential CT profiles are broadly consistent with comparable histological studies, and with the genoarchitecture of teleosts like the zebrafish. Compared to the zebrafish, our study identifies distinct developmental heterochronies in the rosy bitterling, such as a precocious development of the inferior lobe.

Bitterlings are a group of teleost fish (Cyprinifromes: Acheilanathidae) notable for their brood parasitic lifestyle. Bitterling embryos develop as parasites inside the gill chamber of their freshwater mussel hosts. However, little is known about brain development in this species. Here, we have imaged the development of the brain of the Rosy Bitterling (Rhodeus ocellatus) at four embryonic stages (165, 185, 210, 235 hours post-fertilization) using micro-computed tomography (microCT) with special emphasis on developmental regionalization and brain ventricular organization. We provide a detailed neuroanatomical account of the development of the brain divisions with reference to The Atlas of Early zebrafish Brain Development and the updated prosomeric model. Segmentation and three-dimensional visualization of the ventricular system were performed in order to clarify changes in the longitudinal brain axis as a result of cephalic flexure during development. During early embryonic and larval development, we find that histological differentiation, tissue boundaries, periventricular proliferation zones, and ventricular spaces are all recognizable using microCT. Importantly, our approach is validated by the fact that the profile of CT values displayed here in the bitterling brain are consistent with genoarchitecture identified in previous studies. We also find developmental heterochrony of the inferior lobe in the Rosy Bitterling compared to the zebrafish. Our study provides a foundation for future studies of the brain development in the Rosy Bitterling, a valuable model species for studying the evolutionary adaptations associated with brood parasitism.
