On the trail of the 'new head' in Les Treilles [PDF]

open access: yes, 2008
The vertebrate brain develops in association with neighboring tissues: neural crest, placodes, mesoderm and endoderm. The molecular and evolutionary relationships between the forming nervous system and the other craniofacial structures were at the focus ...

A case of holoprosencephaly and a little review

open access: yesHuman Pathology: Case Reports, 2019
Holoprosencephaly (HPE) is a birth defect that occurs during the first weeks of pregnancy and as a result the prosencephalon does not clearly divide in diencephalon, two halves of the telencephalon and lateral ventricles in the brain of the fetus and, in

Increasing Number of Unusual Brain Abnormalities Seen in Rural West Virginia

open access: yesMarshall Journal of Medicine, 2020
The incidence rate of schizencephaly is 1.5 in 100,000 live births and the rate of holoprosencephaly is 1 in 16,000 live births. Both malformations are rare, but our institution has seen a dramatic increase in both malformations in recent years with no ...

Molecular codes defining rostrocaudal domains in the embryonic mouse hypothalamus [PDF]

open access: yes, 2015
The prosomeric model proposes that the hypothalamus is a rostral forebrain entity, placed ventral to the telencephalon and rostral to the diencephalon.

Motor hemiplegia and the cerebral organization of movement in man: II. The myth of the human extrapyramidal system

open access: yesArquivos de Neuro-Psiquiatria, 1989
Following a brief review of the concept of extrapyramidal system, clinical and anatomic evidence is presented against its relative prominence in man.

Neural crest cell-derived pericytes act as pro-angiogenic cells in human neocortex development and gliomas

open access: yesFluids and Barriers of the CNS, 2021
Central nervous system diseases involving the parenchymal microvessels are frequently associated with a ‘microvasculopathy’, which includes different levels of neurovascular unit (NVU) dysfunction, including blood–brain barrier alterations. To contribute

Temporal sequence of gene expression leading caudal prosencephalon to develop a midbrain/hindbrain phenotype [PDF]

open access: yesDevelopmental Dynamics, 2001
AbstractTransplantation of prosomeres 1‐2 into the cerebellar plate were used, by using chick/quail chimeras, to analyse the temporal sequence of the genetic cascade leading the graft to develop a midbrain/hindbrain phenotype. Our results show that (1) at Hamburger and Hamilton (HH) stage 13, Pax2 and En2 are already induced within the graft, before ...

Ontogenetic distribution of the transcription factor Nkx2.2 in the developing forebrain of Xenopus laevis

open access: yesFrontiers in Neuroanatomy, 2011
The expression of the Nkx2.2 gene is involved in the organization of the alar-basal boundary in the forebrain of vertebrates. Its expression in different diencephalic and telencephalic regions, helped to define distinct progenitor domains in mouse and ...

Expression of the neural cell adhesion molecule NCAM in endocrine cells [PDF]

open access: yes, 1989
We examined the expression of the neural cell adhesion molecule NCAM in a number of endocrine tissues of adult rat and in an endocrine tumor cell line. NCAM was found by immunoelectron microscopy to be present on the surface of all endocrine cells in the

Generalized myoclonic epilepsy with photosensitivity in juvenile dogs caused by a defective DIRAS family GTPase 1 [PDF]

open access: yes, 2017
The clinical and electroencephalographic features of a canine generalized myoclonic epilepsy with photosensitivity and onset in young Rhodesian Ridgeback dogs (6 wk to 18 mo) are described.
