Fgf10(+) progenitors give rise to the chick hypothalamus by rostral and caudal growth and differentiation [PDF]

open access: yes, 2017
Classical descriptions of the hypothalamus divide it into three rostro-caudal domains but little is known about their embryonic origins. To investigate this we performed targeted fate-mapping, molecular characterisation and cell cycle analyses in the ...

Interspecies avian brain chimeras reveal that large brain size differences are influenced by cell-interdependent processes. [PDF]

open access: yes, 2012
Like humans, birds that exhibit vocal learning have relatively delayed telencephalon maturation, resulting in a disproportionately smaller brain prenatally but enlarged telencephalon in adulthood relative to vocal non-learning birds. To determine if this

Antenatally diagnosed alobar holoprosencephaly: A report of two cases

open access: yesCHRISMED Journal of Health and Research, 2017
Holoprosencephaly is a complex developmental abnormality of the brain arising from the failure of cleavage of the prosencephalon. The condition termed “holoprosencephaly” includes cyclopia, cebocephaly, ethmocephaly, and median cleft.

Monoaminergic modulation of photoreception in ascidian:evidence for a proto-hypothalamo-retinal territory [PDF]

open access: yes, 2012
Background : The retina of craniates/vertebrates has been proposed to derive from a photoreceptor prosencephalic territory in ancestral chordates, but the evolutionary origin of the different cell types making the retina is disputed.

Ciliogenesis and cerebrospinal fluid flow in the developing Xenopus brain are regulated by foxj1 [PDF]

open access: yes, 2013
Background: Circulation of cerebrospinal fluid (CSF) through the ventricular system is driven by motile cilia on ependymal cells of the brain. Disturbed ciliary motility induces the formation of hydrocephalus, a pathological accumulation of CSF resulting

LATERAL LINE OF THE NURSE SHARK (Ginglymostoma cirratum): BRIEF REVISION

open access: yesEnvironmental Smoke, 2019
The nurse shark(Ginglymostomacirratum), also knownin Portuguese as “tubarãolixa” or “lambaru”, is found mostly in groups of variable size. Specimens inhabit the bottom of the sea, in warm, littoral waters.

A comparative examination of neural circuit and brain patterning between the lamprey and amphioxus reveals the evolutionary origin of the vertebrate visual center [PDF]

open access: yes, 2015
Vertebrates are equipped with so-called camera eyes, which provide them with image-forming vision. Vertebrate image-forming vision evolved independently from that of other animals and is regarded as a key innovation for enhancing predatory ability and ...

Development of posterior hypothalamic neurons enlightens a switch in the prosencephalic basic plan.

open access: yesPLoS ONE, 2011
In rats and mice, ascending and descending axons from neurons producing melanin-concentrating hormone (MCH) reach the cerebral cortex and spinal cord. However, these ascending and descending projections originate from distinct sub-populations expressing ...
