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.

Development of the early axon scaffold in the rostral brain of the small spotted cat shark (Scyliorhinus canicula) embryo [PDF]

open access: yes, 2014
International audienceThe cat shark is increasingly used as a model for Chondrichthyes, an evolutionarily important sister group of the bony vertebrates that include teleosts and tetrapods.

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 ...

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

Alobar Holoprosencephaly in an Aborted American Quarter Horse Fetus

open access: yes, 2022
Holoprosencephaly is a central nervous system malformation, characterized by incomplete or total lack of division of prosencephalon hemispheres, which is commonly accompanied by craniofacial malformations.

Multiple Cephalic Malformations in a Calf

open access: yesAnimals, 2020
Congenital malformations of the central nervous system (CNS) can affect the CNS alone or the CNS and craniofacial structures. Here, we report an unusual and complex congenital cephalic malformation observed in a 3-day-old male crossbreed calf.

Teneurin evolution and brain-specific functions [PDF]

open access: yes, 2012
Teneurins are a novel family of type II transmembrane proteins. They are highly conserved from invertebrates to vertebrates, in which four paralogs exist, called teneurin-1 to -4.

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Genoarchitectonic Compartmentalization of the Embryonic Telencephalon: Insights From the Domestic Cat

open access: yesFrontiers in Neuroanatomy, 2021
The telencephalon develops from the alar plate of the secondary prosencephalon and is subdivided into two distinct divisions, the pallium, which derives solely from prosomere hp1, and the subpallium which derives from both hp1 and hp2 prosomeres. In this
