Supplemental oxygen during stroke is effective to combat brain tissue damage

Scientists have countered findings of previous clinical trials by showing that giving supplemental oxygen to animals during a stroke can reduce damage to brain tissue surrounding the clot.

Study: General anesthesia can cause brain injury in immature rats

Studies by researchers at Wake Forest University School of Medicine have shown that blocking the NMDA receptor in immature rats leads to profound, rapid brain injury and disruption of auditory function as the animals mature.

Brain inflammation not linked to Alzheimer's disease

In a surprising reversal of long-standing scientific belief, researchers at the Mayo Clinic campus in Florida have discovered that inflammation in the brain is not the trigger that leads to buildup of amyloid deposits and development of Alzheimer's disease.

Researchers discover neurons that precisely keep time in the primate brain

Groups of neurons that precisely keep time have been discovered in the primate brain by a team of researchers that includes Dezhe Jin, assistant professor of physics at Penn State University and two neuroscientists from the RIKEN Brain Science Institute in Japan and the Massachusetts Institute of Technology (MIT).

Research in 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.

Novel HIV drug to be studied in cell cultures and patients

A $6 million, five-year federal grant to The Children's Hospital of Philadelphia Research Institute will enable researchers to investigate a novel approach in treating HIV infection---a unique class of drugs focused on developing therapies for psychological and neurological effects in AIDS.

Research study on epileptic seizures in individuals with alcohol withdrawal syndrome

Epileptic seizures are the most dramatic and prominent aspect of the "alcohol withdrawal syndrome" that occurs when a person abruptly stops a long-term or chronic drinking habit. Researchers have shown that the flow of calcium ions into brain cells via voltage-gated calcium channels plays an important role in the generation of alcohol withdrawal seizures, because blocking this flow suppresses these seizures.

Human brains have amazing ability to be energy efficient, say researchers

Our brains, it turns out, are eco-friendly. A study published in Science and reviewed by F1000 Biology members Venkatesh Murthy and Jakob Sorensen reveals that our brains have the amazing ability to be energy efficient.

Specific immune system cells linked to susceptibility of younger people to variant CJD

Specific cells within the immune system could help explain why younger people are more susceptible to variant CJD, scientists believe.

Much remains to be done for autism spectrum disorders, say experts

Scientific understanding and medical treatments for autism spectrum disorders (ASDs) have advanced significantly over the past several years, but much remains to be done, say experts from the Center for Autism Research at The Children's Hospital of Philadelphia who published a scientific review of the field today.

Brain researcher finds how the epilepsy and pain drug works

A Duke University Medical Center researcher who spent years looking for the signals that prompt the brain to form new connections between neurons has found one that may explain precisely how a well-known drug for epilepsy and pain actually works.

Study shows elevated levels of antioxidant urate can slow the progression of Parkinson's disease

By examining data from a 20-year-old clinical trial, a research team based at the MassGeneral Institute for Neurodegenerative Diseases (MGH-MIND) and Harvard School of Public Health (HSPH), has found evidence supporting the findings of their 2008 study - that elevated levels of the antioxidant urate may slow the progression of Parkinson's disease.

Study reveals the importance of cholestrol derivative in brain cell formation

A derivative of cholesterol is necessary for the formation of brain cells, according to a study from the Swedish medical university Karolinska Institutet. The results, which are published in the journal Cell Stem Cell, can help scientists to cultivate dopamine-producing cells outside the body.

How the human brain processes incoming sensory signals amidst background noise

The brain never sits idle. Whether we are awake or asleep, watch TV or close our eyes, waves of spontaneous nerve signals wash through our brains. Researchers at the Salk Institute for Biological Studies studying visual attention have discovered a novel mechanism that explains how incoming sensory signals make themselves heard amidst the constant background rumblings so they can be reliably processed and passed on.

DISC1 linked to proper development and migration of neurons in the brain

Scientists now have a better understanding of a perplexing gene that is associated with susceptibility for a wide spectrum of severely debilitating mental illnesses. Two independent research studies published by Cell Press in the September 24th issue of the journal Neuron provide fascinating insight into the molecular mechanisms that link disrupted-in-schizophrenia 1 (DISC1) with the proper development and migration of neurons in the hippocampus, a brain area involved in learning and memory and associated with the pathology of schizophrenia.

CERE-110 trial to stop the progression of Alzheimer's disease

Researchers in the Memory Disorders Program at Georgetown University Medical Center are now recruiting volunteers for a national gene therapy trial - the first study of its kind for the treatment of patients with dementia due to Alzheimer's disease.

Blood vessels around the brain now converted into production/delivery systems

The blood brain barrier is generally considered an obstacle to delivering therapies from the bloodstream to the brain. However, University of Iowa researchers have discovered a way to turn the blood vessels surrounding brain cells into a production and delivery system for getting therapeutic molecules directly into brain cells.

Neurodegenerative disorders are the second-leading cause of early-onset dementia, says report

Neurodegenerative disorders called frontotemporal dementias (FTD) are the second-leading cause of early-onset dementia in persons under age 65 and can emerge sometimes as early as age 20.
