A vital dye analysis of the timing and pathways of avian trunk neural crest cell migration [PDF]
To permit a more detailed analysis of neural crest cell migratory pathways in the chick embryo, neural crest cells were labelled with a nondeleterious membrane intercalating vital dye, DiI.

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

Unfused transverse foramen of the atlas vertebra in the Neandertal lineage fossils
Abstract In anatomically modern humans, the atlas can display an unfused transverse foramen (UTF) but currently the presence of UTF in the Neandertal lineage is uncertain due to a scarcity of prevalence studies and no exhaustive record of its presence throughout the entire hominin fossil record.

Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Hominoid‐specific calretinin‐immunopositivity of the optic radiation (geniculocalcarine tract)
Calretinin‐immunostained coronal section through the primary (V1) and extrastriate (ExSt) cortex of the lar gibbon. Note that the optic radiation (OR) is strongly calretinin‐immunoreactive. This calretinin‐immunopositivity of the OR distinguishes the Hominoidea from other primates in terms of the neurochemistry of the OR.

Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of
