Success in applying the technique to the basal ganglia, a brain region that is involved in movement disorders such as Parkinson's disease In the brains of humans and non-human primates, over 100 billion nerve cells build up complicated neural circuits and produce higher brain functions. When an attempt is made to perform gene therapy for neurological diseases like Parkinson's disease, it is necessary to specify a responsible neural circuit out of many complicated circuits. Until now,...

Young Birds Use Their Brain To Learn Songs

Brett Smith for RedOrbit.com Male songbirds use a versatile part of the brain to learn their father´s song during the early stages of development, according to a report published yesterday in the online version of Nature. Researchers at the University of California at San Francisco (UCSF) found that Bengalese finch males use a trial-and-error method in learning the song they will use to attract a mate once they reach maturity. The learning process begins around 40 days after...

Working in mice, scientists at Washington University School of Medicine in St. Louis have devised a treatment that prevents the optic nerve injury that occurs in glaucoma, a neurodegenerative disease that is a leading cause of blindness. Researchers increased the resistance of optic nerve cells to damage by repeatedly exposing the mice to low levels of oxygen similar to those found at high altitudes. The stress of the intermittent low-oxygen environment induces a protective response called...

Retinal ganglion cells can recognize directions thanks to amacrine cells The properties of optical stimuli need to be conveyed from the eye to the brain. To do this efficiently, the relevant information is extracted by pre-processing in the eye. For example, some of the so-called retinal ganglion cells, which transmit visual information to the brain via the optic nerve, only react to light stimuli moving in a particular direction. This direction selectivity is generated by inhibitory...

Integrated functional network could explain some mysteries of Parkinson's and dystonia PITTSBURGH -- Researchers at the University of Pittsburgh have found new evidence that the basal ganglia and the cerebellum, two important areas in the central nervous system, are linked together to form an integrated functional network. The findings are available online this week in the Proceedings of the National Academy of Sciences. "The basal ganglia and the cerebellum are two major subcortical...

A new study from the Swedish medical university Karolinska Institutet provides evidence that basic human learning systems use areas of the brain that also exist in the most primitive vertebrates, such as certain fish, reptiles and amphibians. The study involved an investigation into the limbic striatum, one of the evolutionarily oldest parts of the brain, and the ability to learn movements, consciously and unconsciously, through repetition. "Our results strongly substantiate the theories...

Johns Hopkins Scientists Find a Source of Nonallergic Itch Scratching below the surface of a troublesome sensation that's equal parts tingle-tickle-prickle, sensory scientists from Johns Hopkins have discovered in mice a molecular basis for nonallergic itch. Using the itch-inducing compound chloroquine, an antimalarial drug, the team identified that a family of proteins called Mrgprs, found only in a rare subset of nerve cells, functions as itch receptors. A report on the research appears...

Sensory neuronopathies, nerve dysfunction that affects nerves outside the brain and spinal chord, are extremely painful. They include shingles and can be caused by anti-cancer drugs such as cisplatin. In many sensory neuronopathies, the nerves that are dysfunctional are those in a region of the body known as the dorsal root ganglion (DRG), and these conditions are particularly difficult to treat. Dr. Lawrence Chan and colleagues at Baylor College of Medicine, Houston, TX, have developed an...

Ganglia, an open source scalable distributed monitoring system for high-performance computing systems, announced today the release of Ganglia 3.1. Replete with new metric features and a new modular interface, Ganglia 3.1 will bring improved performance and greater configuration options to organizations such as the University of California, Flickr and Stanford Linear Accelerator. Designed for large-scale monitoring environments, Ganglia is based on a hierarchical design targeted at...
