Mental health intervention can help prevent suicides among youth

Roughly 1 million people die by suicide each year. In the U.S., where nearly 36,000 people take their own lives annually, more than 4,600 victims are between the ages of 10 and 24, making suicide the third leading cause of death in this age group.

Scientists discover neurons responsible for light-induced arousal response

Bright light arouses us. Bright light makes it easier to stay awake. Very bright light not only arouses us but is known to have antidepressant effects. Conversely, dark rooms can make us sleepy. It's the reason some people use masks to make sure light doesn't wake them while they sleep.

Cancer cells maintain rapid proliferation due to PK-M2 enzyme

Cancer cells maintain their life-style of extremely rapid growth and proliferation thanks to an enzyme called PK-M2 (pyruvate kinase M2) that alters the cells' ability to metabolize glucose - a phenomenon known as the Warburg effect.

Pupil can constrict without any input from brain

You've seen it on television: A doctor shines a bright light into an unconscious patient's eye to check for brain death. If the pupil constricts, the brain is OK, because in mammals, the brain controls the pupil. Or does it? Now, researchers at Johns Hopkins have discovered that in most mammals, in fact in most vertebrates, the pupil can constrict without any input from the brain.

Clinical-grade viral vector can cure choroideremia

Researchers at Ohio State University Medical Center and Nationwide Children's Hospital have developed a viral vector designed to deliver a gene into the eyes of people born with an inherited, progressive form of blindness that affects mainly males.

Study highlights profound impact of maternal separation on infants

A woman goes into labor, and gives birth. The newborn is swaddled and placed to sleep in a nearby bassinet, or taken to the hospital nursery so that the mother can rest. Despite this common practice, new research published in Biological Psychiatry provides new evidence that separating infants from their mothers is stressful to the baby.

Cypin protein may prevent long-term brain damage after stroke

One of two proteins that regulate nerve cells and assist in overall brain function may be the key to preventing long-term damage as a result of a stroke, the leading cause of disability and third leading cause of death in the United States.

Study supports existence of metastable frequency-band-dependent scaffold of brain connectivity

Over the past two decades, the increased ability to analyze relationships among neural structures has provided novel insights into brain function. Most network approaches, how-ever, focus on static representations of the brain's physical or statistical connectivity.

Hippocampus supports both recollection and familiarity memories

Human memory has historically defied precise scientific description, its biological functions broadly but imperfectly defined in psychological terms. In a pair of papers published in the November 2 issue of The Journal of Neuroscience, researchers at the University of California, San Diego report a new methodology that more deeply parses how and where certain types of memories are processed in the brain, and challenges earlier assumptions about the role of the hippocampus.

Internet-based communication improves teenagers' use of topical acne therapy

Tech-savvy teens with acne used their medicine more frequently when they also took part in a web-based survey, a new study from Wake Forest Baptist Medical Center finds.

AAN names 30 neurologists to attend Palatucci Advocacy Leadership Forum

The American Academy of Neurology has named 30 neurologists from around the world to attend the esteemed Donald M. Palatucci Advocacy Leadership Forum, January 12-15, 2012, in Austin, Texas.

Researchers discover biomarker for earlier diagnosis of MS

Researchers from the Department of Neurology at NYU Langone Medical Center identified for the first time that changes in the tissue located at the junction between the outer and inner layers of the brain, called "blurring", may be an important, non-invasive biomarker for earlier diagnosis and the development of new therapies for degenerative brain conditions, such as multiple sclerosis.

Oscillatory signals in basal ganglia cause motor deficits in Parkinson's

The research group headed by Professor Atsushi Nambu and Professor Masahiko Takada has shown that the 'oscillatory' nature of electrical signals in subcortical nuclei, the basal ganglia, causes severe motor deficits in Parkinson's disease, by disturbing the information flow of motor commands.

Deficits in endocannabinoid function may contribute to eating disorders

A new report in Biological Psychiatry suggests that deficits in endocannabinoid function may contribute to anorexia nervosa and bulimia.

Dementia people with stroke more likely to become disabled and not return home

New research shows people with dementia who have a stroke are more likely to become disabled and not return home compared to people who didn't have dementia at the time they had a stroke.

J&JPRD submits NUCYNTA ER sNDA to FDA for DPN associated neuropathic pain

Johnson & Johnson Pharmaceutical Research & Development, L.L.C. announced today that it has submitted a supplemental New Drug Application to the U.S. Food and Drug Administration for NUCYNTA ER (tapentadol) extended-release tablets, an oral analgesic, for the management of neuropathic pain associated with diabetic peripheral neuropathy in adults.

Scientists pinpoint brain circuitry linked to decision-making

What drives addicts to repeatedly choose drugs, alcohol, cigarettes, overeating, gambling or kleptomania, despite the risks involved? Neuroscientists at the University of California, Berkeley, have pinpointed the exact locations in the brain where calculations are made that can result in addictive and compulsive behavior.

Researchers identify FMRP protein as key player in RNA editing

The most common form of heritable cognitive impairment is Fragile X Syndrome, caused by mutation or malfunction of the FMR1 gene. Loss of FMR1 function is also the most common genetic cause of autism. Understanding how this gene works is vital to finding new treatments to help Fragile X patients and others.

First report on how patterns of 5-hmC's distribution change in mouse brain during development

In 2009, the DNA alphabet expanded. Scientists discovered that an extra letter or "sixth nucleotide" was surprisingly abundant in DNA from stem cells and brain cells.
