Sonic hedgehog promotes the migration and proliferation of optic nerve oligodendrocyte precursors.

2007

Optic nerve (ON) oligodendrocyte precursors (OPCs) are generated under the influence of the Sonic hedgehog (Shh) in the preoptic area from where they migrate to colonise the entire nerve. The molecular events that control this migration are still poorly understood. Recent studies suggested that Shh is often used by the same cell population to control different processes, including cell proliferation and migration, raising the possibility that Shh could contribute to these aspects of OPC development. In support of this idea, we show here that Shh induces the proliferation of OPCs derived from embryonic mouse ON explants and acts as a chemoattractant for their migration. In ovo injections of …

Cellular Composition and Organization of the Subventricular Zone and Rostral Migratory Stream in the Adult and Neonatal Common Marmoset Brain

2011

The adult subventricular zone (SVZ) of the lateral ventricle contains neural stem cells. In rodents, these cells generate neuroblasts that migrate as chains toward the olfactory bulb along the rostral migratory stream (RMS). The neural-stem-cell niche at the ventricular wall is conserved in various animal species, including primates. However, it is unclear how the SVZ and RMS organization in nonhuman primates relates to that of rodents and humans. Here we studied the SVZ and RMS of the adult and neonatal common marmoset (Callithrix jacchus), a New World primate used widely in neuroscience, by electron microscopy, and immunohistochemical detection of cell-type-specific markers. The marmoset …

A Comparative Study on the Implementation of the Free Movement Directive: Transposition, Application and Enforcement in Belgium, Italy and the UK Com…

The Free Movement Directive is the key EU legal instrument that regulates the free movement of persons within the thirty-one countries that make up the European Economic Area. Implementation of Directive 2004/38 by the Member States has been far from satisfactory and the Commission has deplored the fact that not a single Member State had been able to implement the Directive correctly. The enforcement action that the Commission has so far taken does not appear to have necessarily been linked to how well transposition complies with the Directive in individual Member States. In other words, the way in which the Directive has been written into national law does not seem to be the only factor th…

Increased Gamma Connectivity in the Human Prefrontal Cortex during theBereitschaftspotential

2017

The Bereitschaftspotential (BP) is a slow negative cortical potential preceding voluntary movement. Since movement preparation is dependent upon the synchronous activity of a variety of neurons, BP may develop through the exchange of information among motor-related neurons. However, the relationship between BP and information flow is not yet well-known. In the present study, we aimed to investigate how the connectivity in the prefrontal cortex (PFC) changes during the occurrence of BP. Electrocorticography (ECoG) was recorded in five patients with epilepsy. The subjects performed self-paced hand grasping. We compared the intraregional connectivity between PFC and non-PFC regions using parti…
