Researchers explain how nerve cells transmit electrical signals

Billions of brain cells are communicating at any given moment. Like an organic supercomputer they keep everything going, from breathing to solving riddles, and "programming errors" can lead to serious conditions such as schizophrenia, Parkinson's disease and attention-deficit hyperactivity disorder.

Rush University researchers identify potential new way to prevent Alzheimer's disease progression

Neurological researchers at Rush University Medical Center have found a new therapeutic target that can potentially lead to a new way to prevent the progression of Alzheimer's disease. The target called neutral sphingomyelinase (N-SMase) is a protein that when activated, can cause a chain of reactions in the cell leading to neuronal death and memory loss.

Brain wolfs energy even to stop thinking

Ever wonder why it's such an effort to forget about work while on vacation or to silence that annoying song that's playing over and over in your head?

Research on signaling pathways may help to design therapy for neurodevelopmental disorders

Researchers at the Center for Neuroscience Research at Children's National Medical Center have discovered that the two major types of signaling pathways activated during brain cell development-the epidermal growth factor receptor pathway and the Notch pathway-operate together to determine how many and which types of brain cells are created during growth and repair in developing and adult brains.

Researchers to contribute to brain circuit mapping in Human Connectome Project

Thirty-three researchers at nine institutions will contribute to the Human Connectome Project (http://www.humanconnectome.org/consortia). Using powerful, custom-built brain scanners, a supercomputer, new brain analysis techniques and other state-of-the-art resources, they will trace the anatomical 'wires' that interconnect thousands of different regions of the human brain's gray matter.

Mechanism linking brain activity to sleep discovered

Washington State University researchers have discovered the mechanism by which the brain switches from a wakeful to a sleeping state. The finding clears the way for a suite of discoveries, from sleeping aids to treatments for stroke and other brain injuries.

Study finds antibiotic safe for treatment of stroke and good companion therapy for tPA

An antibiotic appears to be a safe treatment for stroke and a good companion therapy for tPA, the clot buster that is currently the only FDA-approved drug therapy, researchers report.

Researchers find amyloid precursor protein function in Alzheimer's disease

In people with Alzheimer's, the brain becomes riddled with clumps of protein, forming what are known as amyloid plaques. Now, a report appearing in the September 17th print issue of Cell appears to have found a function for the amyloid precursor protein that yields the prime ingredient in those plaques.

Researchers develop GAL4/UAS system to study human neurological diseases

A team of University of Oklahoma researchers studying neurobiology in fruit flies (Drosophila) has developed a new method for understanding brain function with potential applications in studies of human neurological diseases.

Researchers discover generation of pyramidal neurons by glial cell precursors

In an unanticipated finding, researchers at the UC Davis School of Medicine have discovered that, during early adulthood, the brain produces new excitatory neurons, and that these neurons arise from non-neuronal support cells in an area of the brain that processes smell.

Researches discover reducing tau protein level can prevent Αβ protein transport in Alzheimer’s disease

Amyloid beta (Αβ) proteins, widely thought to cause Alzheimer's disease (AD), block the transport of vital cargoes inside brain cells. Scientists at the Gladstone Institute of Neurological Disease (GIND) have discovered that reducing the level of another protein, tau, can prevent Aβ from causing such traffic jams.

Obesity key lies in the brain: Study

According to a new international study led in Australia by the Monash Obesity and Diabetes Institute (MODI) at Monash University, high fat diets that lead to obesity and weight gain make the brain immune to signals that tell the body to stop eating and to burn energy.

Researchers investigate brain network to understand mind disorders

Uncovering the secrets of the brain requires an intense network of collaborative research. Building on a tool that was co-developed in his laboratory and described in a recent issue of Brain, Dr. Yaniv Assaf of Tel Aviv University's Department of Neurobiology is collaborating with an international team of scientists to understand how different parts of the human brain "connect" and to turn this information into a "brain atlas."

Research on fruit flies suggest starvation allows sleep deprivation

As anyone who has ever struggled to keep his or her eyes open after a big meal knows, eating can induce sleepiness. New research in fruit flies suggests that, conversely, being hungry may provide a way to stay awake without feeling groggy or mentally challenged.

Continuous boosting of natural painkiller shuts down brain cell receptor response

ERepeatedly boosting brain levels of one natural painkiller soon shuts down the brain cell receptors that respond to it, so that the painkilling effect is lost, according to a surprising new study led by Scripps Research Institute and Virginia Commonwealth University scientists. The study has important implications for drug development.

Human umbilical cord blood cells appear to protect astrocytes from cell death: Research

Human umbilical cord blood cells (HUCB) used to treat cultured rat brain cells (astrocytes) deprived of oxygen appear to protect astrocytes from cell death after stroke-like damage, reports a team of researchers from the University of South Florida (USF) Department of Neurosurgery and Brain Repair.

Berries help aging brain stay healthy

Scientists today reported the first evidence that eating blueberries, strawberries, and acai berries may help the aging brain stay healthy in a crucial but previously unrecognized way. Their study, presented at the 240th National Meeting of the American Chemical Society (ACS), concluded that berries, and possibly walnuts, activate the brain's natural "housekeeper" mechanism, which cleans up and recycles toxic proteins linked to age-related memory loss and other mental decline.

New diagnostic tool proves cost-effective in identifying rare genetic disorders

Mutations in a single gene can cause several types of developmental brain abnormalities that experts have traditionally considered different disorders. With support from the National Institutes of Health, researchers found those mutations through whole exome sequencing - a new gene scanning technology that cuts the cost and time of searching for rare mutations.

New squeeze test for screening potential drugs for Alzheimer's

Brain cells exposed to a form of the amyloid beta protein, the molecule linked to Alzheimer's disease, become stiffer and bend less under pressure, researchers at UC Davis have found. The results reveal one mechanism by which the amyloid protein damages the brain, a finding that could lead to new ways to screen drugs for Alzheimer's and similar diseases.

Study finds ketamine restores connection in chronic stress affected brain cells

Yale researchers have discovered how a novel anti-depressant can take effect in hours, rather than the weeks or months usually required for most drugs currently on the market.
