The avian tectobulbar tract: development, explant culture, and effects of antibodies on the pattern of neurite outgrowth [PDF]

open access: yes, 1990
The tectobulbar tract is the first long-distance projecting fiber pathway to appear during the development of the avian optic tectum (dorsal half of the mesencephalon).

Molecular Programming of Mesodiencephalic Dopaminergic Neuronal Subsets

open access: yesFrontiers in Neuroanatomy, 2017
Dopamine neurons of the substantia nigra compacta (SNc) and ventral tegmental area (VTA) are critical components of the neuronal machinery to control emotion and movement in mammals.

β-catenin is required in the neural crest and mesencephalon for pituitary gland organogenesis

open access: yesBMC Developmental Biology, 2016
BackgroundThe pituitary gland is a highly vascularized tissue that requires coordinated interactions between the neural ectoderm, oral ectoderm, and head mesenchyme during development for proper physiological function. The interactions between the neural

Anxiety and Depression Are Related to Higher Activity of Sphingolipid Metabolizing Enzymes in the Rat Brain

open access: yesCells, 2020
Changes in sphingolipid metabolism have been suggested to contribute to the pathophysiology of major depression. In this study, we investigated the activity of acid and neutral sphingomyelinases (ASM, NSM) and ceramidases (AC, NC), respectively, in ...

Isolation, characterization, and substrate properties of the external limiting membrane from the avian embryonic optic tectum [PDF]

open access: yes, 1990
The external limiting membrane of the avian embryonic optic tectum is isolated by mechanically separating the neuronal mesencephalon from the overlying mesenchymal tissue.
