Transcranial magnetic stimulation enhances visual abilities in healthy adults

Using transcranial magnetic stimulation (TMS), an international team led by researchers from the Centre de Recherche de l'Institut du Cerveau et de la Moelle Epinière (CNRS / Inserm / UPMC) has succeeded in enhancing the visual abilities of a group of healthy subjects.

Scientists identify rhythmic brain cell firing patterns in the motor cortex

A new model for understanding how nerve cells in the brain control movement may help unlock the secrets of the motor cortex, a critical region that has long resisted scientists' efforts to understand it, researchers report June 3 in Nature.

Scientists propose new theory of the brain activity behind arm movements

Unlike their visual cousins, the neurons that control movement are not a predictable bunch. Scientists working to decode how such neurons convey information to muscles have been stymied when trying to establish a one-to-one relationship between a neuron's behavior and external factors such as muscle activity or movement velocity.

Initial data to construct first whole-brain wiring diagram of vertebrate brain

Neuroscientists at Cold Spring Harbor Laboratory (CSHL) reached an important milestone today, publicly releasing the first installment out of 500 terabytes of data so far collected in their pathbreaking project to construct the first whole-brain wiring diagram of a vertebrate brain, that of the mouse.

Molecular structure of APP protein could lead to new therapeutics for AD

The molecular structure of a protein involved in Alzheimer's disease - and the surprising discovery that it binds cholesterol - could lead to new therapeutics for the disease, Vanderbilt University investigators report in the June 1 issue of the journal Science.

New therapy approach for patients blind on one side

Patients who are blind in one side of their visual field benefit from presentation of sounds on the affected side. After passively hearing sounds for an hour, their visual detection of light stimuli in the blind half of their visual field improved significantly.

Use of transplanted induced pluripotent stem cells could lead to new treatments for HD

Researchers from South Korea, Sweden, and the United States have collaborated on a project to restore neuron function to parts of the brain damaged by Huntington's disease (HD) by successfully transplanting HD-induced pluripotent stem cells into animal models.

Exendin-4 significantly minimizes damage in TBI animal models

Although the death toll is relatively low for people who suffer from traumatic brain injury (TBI), it can have severe, life-long consequences for brain function. TBI can impair a patient's mental abilities, impact memory and behavior, and lead to dramatic personality changes. And long-term medical treatment carries a high economic cost.

Glia seem to play two opposing roles in protecting nerve cells from damage

A protein produced by the central nervous system's support cells seems to play two opposing roles in protecting nerve cells from damage, an animal study by Johns Hopkins researchers suggests: Decreasing its activity seems to trigger support cells to gear up their protective powers, but increasing its activity appears to be key to actually use those powers to defend cells from harm.

Neural protein plays two opposing roles

A protein produced by the central nervous system’s support cells seems to play two opposing roles in protecting nerve cells from damage, an animal study by Johns Hopkins researchers suggests: Decreasing its activity seems to trigger support cells to gear up their protective powers, but increasing its activity appears to be key to actually use those powers to defend cells from harm.

Researchers develop new technique that converts stem cells into brain cells

A new technique that converts stem cells into brain cells has been developed by researchers at Lund University. The method is simpler, quicker and safer than previous research has shown and opens the doors to a shorter route to clinical cell transplants.

UCSD scientists receive new CIRM grants to conduct stem cell-based research

Five scientists from the University of California, San Diego and its School of Medicine have been awarded almost $12 million in new grants from the California Institute for Regenerative Medicine (CIRM) to conduct stem cell-based research into regenerating spinal cord injuries, repairing gene mutations that cause amyotrophic lateral sclerosis and finding new drugs to treat heart failure and Alzheimer's disease.

UCSF scientists aim to use embryonic stem cells for treatment of neuropathic pain

Chronic pain, by definition, is difficult to manage, but a new study by UCSF scientists shows how a cell therapy might one day be used not only to quell some common types of persistent and difficult-to-treat pain, but also to cure the conditions that give rise to them.

Human olfactory bulb differs from that of other mammals

Research from Karolinska Institutet in Sweden shows that the human olfactory bulb - a structure in the brain that processes sensory input from the nose - differs from that of other mammals in that no new neurons are formed in this area after birth. The discovery, which is published in the scientific journal Neuron, is based on the age-determination of the cells using the carbon-14 method, and might explain why the human sense of smell is normally much worse than that of other animals.

Scientists discover how microglia detect the site of injury

Like emergency workers rushing to a disaster scene, cells called microglia speed to places where the brain has been injured, to contain the damage by 'eating up' any cellular debris and dead or dying neurons. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have now discovered exactly how microglia detect the site of injury, thanks to a relay of molecular signals.

Study sheds light on role of microglia in the normal brain

Researchers have shown in mice how immune cells in the brain target and remove unused connections between brain cells during normal development. This research, supported by the National Institutes of Health, sheds light on how brain activity influences brain development, and highlights the newly found importance of the immune system in how the brain is wired, as well as how the brain forms new connections throughout life in response to change.

Brain cells prune circuits in the brain by eating away excess synapses

We’re born with our brains prewired, but as information comes in from our environment, this circuitry is updated. A study from Boston Children’s Hospital provides a new glimpse of how this happens: Brain cells known as microglia, tuned into the crosstalk between neurons, literally engulf unnecessary connections, known as synapses, and prune them away.

Astrocytes appear to retaliate against AD

When brain cells start oozing too much of the amyloid protein that is the hallmark of Alzheimer's disease, the astrocytes that normally nourish and protect them deliver a suicide package instead, researchers report.

Researchers to initiate Crenezumab clinical trial to treat Alzheimer's

After an announcement by federal officials approving clinical trials for the drug Crenezumab, researchers searching for a way to treat Alzheimer's Disease are gearing up for a rare study that will allow them to test a therapy for a genetically predestined disease -- before its onset.

Researchers generate neuronal cells from patients with Fragile X syndrome

Researchers at the Hebrew University of Jerusalem have achieved, for the first time, the generation of neuronal cells from stem cells of Fragile X patients. The discovery paves the way for research that will examine restoration of normal gene expression in Fragile X patients.
