France 2 - L'école, les jeunes et le langage (Je dis donc je suis) In mice, single population of stem cells contributes to lifelong hippocampal neurogenesis. Scientists once thought that mammals entered adulthood with all of the neurons they would ever have, but studies from the 60s found that new neurons are generated in certain parts of the adult brain and pioneering studies from the 90s helped identify their origins and function.
In the latest update, a team of researchers has shown in mice that a single lineage of neural progenitors contributes to embryonic, early postnatal, and adult neurogenesis in the hippocampus, and that these cells are continuously generated throughout a lifetime. The study appears March 28 in the journal Cell. "Conceptually, this suggests that our brains have the capacity for continuous improvement, adaptation, and incorporation of new cells into the circuitry," says senior author Hongjun Song of the Perelman School of Medicine at the University of Pennsylvania. "This turns out to be very important, because the hippocampus is well known to be important for learning, memory, and mood regulation.
" Brain connection between memory and feeding behavior to control overeating. Food is, generally speaking, a good thing.
In addition to being quite tasty, it is also necessary for survival. That's why animals have evolved robust physiological systems that attract them to food and keep them coming back for more. Now, research in mice reveals the existence of brain cells that have the opposite effect, curbing an animal's impulse to eat. Des scientifiques fabriquent des vaisseaux sanguins à partir de tissus de cadavres et les ramènent à la vie chez des patients vivants. Les vaisseaux sanguins endommagés par une maladie cardiovasculaire peuvent devenir un problème très grave s’ils ne sont pas réparés à temps.
Pour ce faire, il existe deux options : remplacer les vaisseaux sanguins endommagés par d’autres vaisseaux prélevés dans une autre partie de votre corps, ou en créer un nouveau à partir de zéro. Malheureusement, la première option a ses limites. Et les types de vaisseaux synthétiques que nous utilisons actuellement pour la deuxième option ne sont pas sans risque… C’est pour cette raison que des chercheurs étudient une troisième option : soit d’en fabriquer à partir de cadavres.

Ken Collins; has been speaking about the need to consider how the Limbic System and the flight or flight response affects individuals living with brain injuries with regard to stress. Understanding how stress impacts the manner in which individuals respond and relate to life plays a major role in each individual’s recovery process. The fight or flight response can be exacerbated by a number of factors in the lives of individuals living with the impact of a brain injury.
The reaction to these factors, for individuals living with brain injuries; can be accelerated and exacerbated by filters in the brain that have been damaged due to a brain injury. Understanding stressors and how these stressors impact our recovery process as brain injury survivors is very important. Understanding how these filters have been damaged due to an injury to a brain injury can be very helpful.
Techniques to quiet the “storm” at the time of the “stressor” help to relieve the “stressor”.

A new discipline sits at the intersection of neuroscience and engineering, where lessons learned from circuits, networks and chips are combined with the latest findings on brain circuitry.
Written by: Matt Windsor Media contact: Yvonne Taunton Programming computers has never been easier. The real challenge is figuring out how to hack the circuits inside your head. The words “brain-machine interface” may sound like science fiction, but they are approaching reality thanks to the BRAIN Initiative from the National Institutes of Health. Launched by President Barack Obama in 2013, this moonshot already has poured $400 million into a major effort to understand — and interact with — brain circuits. “This is where the field of neuroscience is going,” said Lori McMahon, Ph.D., Jarman F.
