In an effort to identify the underlying causes of neurological disorders that impair motor functions such as walking and breathing, UCLA researchers have developed a novel system to measure the communication between stem cell-derived motor neurons and muscle cells in a Petri dish. The study provides an important proof of principle that functional motor circuits can be created outside of the body using stem cell-derived neurons and muscle cells, and that the level of communication, or...

Human Brain Evolution Triggered By Duplicate Gene
2012-05-04 08:21:12

Brett Smith for Redorbit.com Scientists may have just found a ℠missing link´ in the form of a partial, duplicate gene that appears to be responsible for human brain development - the most distinguishing characteristic of our species. The genetic variation occurred in man´s ape-like ancestor about two or three million years ago, according to a pair of studies published online in the journal Cell. A team led by researchers at the Scripps Research Institute found that a...

Waking Embryos Before They Are Born

Under some conditions, the brains of embryonic chicks appear to be awake well before those chicks are ready to hatch out of their eggs. That's according to an imaging study published online on May 3 in Current Biology, a Cell Press publication, in which researchers woke chick embryos inside their eggs by playing loud, meaningful sounds to them. Playing meaningless sounds to the embryos wasn't enough to rouse their brains. The findings may have implications not only for developing chicks...

UI researchers explore how one cell binds itself to another, shedding light on neurodevelopmental disorders University of Iowa biologists have advanced the knowledge of human neurodevelopmental disorders by finding that a lack of a particular group of cell adhesion molecules in the cerebral cortex–the outermost layer of the brain where language, thought and other higher functions take place –disrupts the formation of neural circuitry. Andrew Garrett, former neuroscience...

They say you can´t teach an old dog new tricks. Fortunately, this is not always true. Researchers at the Netherlands Institute for Neuroscience (NIN-KNAW) have now discovered how the adult brain can adapt to new situations. Their study may be significant in the treatment of neurodevelopmental disorders such as epilepsy, autism and schizophrenia. Ability to learn Our brain processes information in complex networks of nerve cells. The cells communicate and excite one another through...

Can one feel too attached? Does one need to let go to mature? Neural stem cells have this problem, too. As immature cells, neural stem cells must stick together in a protected environment called a niche in order to divide so they can make all of the cells that populate the nervous system. But when it's time to mature, or differentiate, the neural stem cells must stop dividing, detach from their neighbors and migrate to where they are needed to form the circuits necessary for humans to...

New research from UC Davis and Washington State University shows that PCBs, or polychlorinated biphenyls, launch a cellular chain of events that leads to an overabundance of dendrites -- the filament-like projections that conduct electrochemical signals between neurons -- and disrupts normal patterns of neuronal connections in the brain. "Dendrite growth and branching during early development is a finely orchestrated process, and the presence of certain PCBs confuses the conductor of that...

Lack of regulator can cause neural tube defects Researchers at the University of Colorado School of Medicine have found that lack of a specific gene interrupts neural tube closure, a condition that can cause death or paralysis. "The neural tube is the beginning of the brain and spinal cord," said the study's lead investigator Lee Niswander, Ph.D., professor of pediatrics at the CU School of Medicine. "A defect in the mLin41 gene doesn't allow the tube to close because not enough neural...

Researchers at the Institute of Neurosciences at Universitat Autònoma de Barcelona (INc-UAB) identified the fundamental role played by the Nurr1 gene in neuron survival associated with synaptic activity. The discovery, published in the Journal of Biological Chemistry, allows scientists to study a new target that could help to understand the relationship between alterations in neural connections, which are known to cause early cognitive deficit, and the neurodegeneration...

(Ivanhoe Newswire) — Autism is a highly heritable neurodevelopmental disorder, yet the genetic underpinnings in the brain at young ages have remained largely unknown. But for the first time, researchers have identified in young autism patients genetic mechanisms involved in abnormal early brain development and overgrowth that occurs in the disorder Until now, few studies have been able to investigate whole-genome gene expression and genotype variation in the brains of young patients...
