You wouldn't want a car with no brakes. It turns out that the developing brain needs them, too. Researchers at the Stanford University School of Medicine have identified a set of molecular brakes that stabilize the developing brain's circuitry. Moreover, experimentally removing those brakes in mice enhanced the animals' performance in a test of visual learning, suggesting a long-term path to therapeutic application. In a study to be published Nov. 25 in Neuron, Carla Shatz, PhD, professor of...

UCSF scientists studying nerve cells in fruit flies have uncovered a new function for a gene whose human equivalent may play a critical role in schizophrenia. Scientists have known that the mutated form of the human gene "“ one of three consistently associated with schizophrenia "“ mildly disrupts the transmission of chemical signals between nerve cells in the brain. The new study focuses on genes involved in "adaptive plasticity," the capacity of nerve cells to compensate for a...

MU occupational therapy professor says recovery from brain injuries can last a lifetime Until recently, scientists believed that, following a stroke, a patient had about six months to regain any lost function. After that, patients would be forced to compensate for the lost function by focusing on their remaining abilities. Although this belief has been refuted, a University of Missouri occupational therapy professor believes that the current health system is still not giving patients enough...

Regularly playing a musical instrument changes the anatomy and function of the brain and may be used in therapy to improve cognitive skills. There is growing evidence that musicians have structurally and functionally different brains compared with non-musicians. In particular, the areas of the brain used to process music are larger or more active in musicians. Even just starting to learn a musical instrument can change the neurophysiology of the brain. Lutz Jäncke, a member of Faculty of...

A research collaboration led by biologists and neuroscientists at the University of Pennsylvania has found a molecular pathway in the brain that is the cause of cognitive impairment due to sleep deprivation. Just as important, the team believes that the cognitive deficits caused by sleep deprivation, such as an inability to focus, learn or memorize, may be reversible by reducing the concentration of a specific enzyme that builds up in the hippocampus of the brain. It is known that sleep...

Research into specific cells and circuitry affected by addiction may help guard against relapse New research using animal models is enabling a deeper understanding of the neurobiology of compulsive drug addiction in humans "” knowledge that may lead to more effective treatment options to weaken the powerful cravings that cause people to relapse. The findings were released today at Neuroscience 2009, the Society for Neuroscience's annual meeting and the world's largest source of emerging...

BELGRADE, SERBIA, Oct. 21 /PRNewswire-FirstCall/ - Hard to Treat Diseases, Inc. (HTDS:PK), http://www.htdsmedical.com announced that researchers in its Slavica BioChem division have reported new positive results of experiments in which the potential beneficial effects of Hyperbaric oxygenation (HBO) after traumatic brain injury have been explored. In the previous press release (reported at July 27, 2009) they revealed that repetitive HBO treatments, which started 1 hour after traumatic brain...

For an animal that has a brain about the size of two grains of sand, a lot of plasticity seems to be packed into the head of the tropical paper wasp Polybia aequatorialis. Researchers from the universities of Washington and Texas have found that the brain architecture of these wasps undergoes dramatic changes as they cycle through a sequence of specialized jobs during their lives. The scientists previously had discovered that parts of the brains of this wasp species enlarged as the animal...

Chaos brews in the brains of newborns: the nerve cells are still bound only loosely to each other. Under the leadership of Academy Research Fellow Sari Lauri, a team of researchers at the University of Helsinki has been studying for years how a neural network capable of processing information effectively is created out of chaos. The team has now found a new kind of mechanism that adjusts the functional development of nerve cell contacts. The results were published in early September as the...
