Morphogenesis underlying the development of the everted teleost telencephalon
Background Although the mechanisms underlying brain patterning and regionalization are very much conserved, the morphology of different brain regions is extraordinarily variable across vertebrate phylogeny.

Morphological and Histometric Alterations in Gonadal and Neural Tissues of Native and Non-Native Fishes From the Lower Doce River Basin in Southeastern Brazil. [PDF]
ABSTRACT The ichthyofauna of the lower Doce River basin has been exposed to multiple anthropogenic stressors. Among these, the collapse of the Fundão mining tailings dam in Mariana, Minas Gerais, Brazil, in 2015 resulted in massive fish mortality and widespread contamination of aquatic environments.

Zebrafish telencephalon acquires an everted morphology by a two-step process that occurs from 1 to 5 days post-fertilization (dpf). Little is known about how this process affects the positioning of discrete telencephalic cell populations, hindering our ...

Whole-Brain Monosynaptic Inputs and Outputs of Corticotropin-Releasing Hormone Neurons of the Paraventricular Nucleus of the Hypothalamus in Male Mice. [PDF]
Using rabies‐based monosynaptic retrograde tracing and AAV anterograde labeling, this study maps the brain‐wide inputs and outputs of PVN CRH neurons, identifying them as a key hub coordinating stress, autonomic, and behavioral responses. ABSTRACT Objective The paraventricular nucleus of the hypothalamus (PVN) is a central hub integrating ...

Collective decision-making under predator threat is faster in guppy shoals selected for larger telencephalon size [PDF]
Avoiding predation is essential for most animals. For group-living species, effective predator avoidance relies on making fast and accurate collective decisions.

Gene expression mapping of conserved GABAergic interneuron markers in developing zebrafish [PDF]
γ-Aminobutyric acid (GABA)-expressing interneurons play a crucial role in regulating brain activity, and their impairment or loss is linked to various neurological disorders.

Asparagine Synthetase Deficiency: Neuropathological Evidence of Disrupted Cortical Development. [PDF]
ABSTRACT Asparagine synthetase deficiency (ASNSD) is a rare metabolic disease causing congenital microcephaly, severe developmental delay, and spastic quadriplegia. Although the central nervous system is severely affected, other organ systems appear unaffected by asparagine deficiency.

The mammalian DM domain transcription factor Dmrta2 is required for early embryonic development of the cerebral cortex. [PDF]
Development of the mammalian telencephalon is precisely organized by a combination of extracellular signaling events derived from signaling centers and transcription factor networks.

Proper brain development requires precisely controlled phases of stem cell proliferation, lineage specification, differentiation, and migration. Lineage specification depends partly on concentration gradients of chemical cues called morphogens.

In all vertebrates, the most dorsal region of the telencephalon gives rise to the pallium, which in turn, is formed by at least four evolutionarily conserved histogenetic domains.
