Researchers at MIT and the University of Vienna have created an imaging system that reveals neural activity throughout the brains of living animals. This technique, the first that can generate 3-D movies of entire brains at the millisecond timescale, could help scientists discover how neuronal networks process sensory information and generate behavior.

Researchers at The University of Akron are again spinning inspiration from spider silk—this time to create more efficient and stronger commercial and biomedical adhesives that could, for example, potentially attach tendons to bones or bind fractures.
Harvard Stem Cell Institute (HSCI) scientists at Massachusetts General Hospital have a potential solution for how to more effectively kill tumor cells using cancer-killing viruses. The investigators report that trapping virus-loaded stem cells in a gel and applying them to tumors significantly improved survival in mice with glioblastoma multiforme, the most common brain tumor in human adults and also the most difficult to treat.
Acupuncture is a traditional Chinese medicine technique that is often used to help improve the level of consciousness in patients with disorder of consciousness (DOC). However, the responses to stimulation of acupoints in patients with DOC are not fully understood. Hao Zhang and colleagues from China Rehabilitation Research Center found that acupuncture at the Yongquan acupoints induced stronger neuronal activity than acupuncture at the sham acupoints shown on positron emission tomography (PET).
In a recent study reported in the Neural Regeneration Research (Vol. 9, No. 5, 2014), repeated-pulse transcranial magnetic stimulation was administered to healthy people at the left Guangming (GB37) and a mock point, and calculated the sample entropy of electroencephalogram signals using nonlinear dynamics. Additionally, researchers compared electroencephalogram sample entropy of signals in response to visual stimulation before, during, and after repeated-pulse transcranial magnetic stimulation at the Guangming.
In Parkinson's disease (PD), dopamine-producing nerve cells that control our movements waste away. Current treatments for PD therefore aim at restoring dopamine contents in the brain. In a new study from Lund University, researchers are attacking the problem from a different angle, through early activation of a protein that improves the brain's capacity to cope with a host of harmful processes. Stimulating the protein, called Sigma-1 receptor, sets off a battery of defence mechanisms and restores lost motor function.
Researchers from the University of California, San Diego School of Medicine and Naval Health Research Center have found that mindfulness training – a combination of meditation and body awareness exercises – can help U.S. Marine Corps personnel prepare for and recover from stressful combat situations.
Interrupted breathing during sleep affects brain neurons necessary to regulate heart rate
Sufferers of a common sleep-breathing disorder have diminished activity among neurons responsible for keeping heart rate low, reveals a new study published today [16 May] in The Journal of Physiology.
AURORA, Colo. (May 15, 2014) – The proportion of marijuana-positive drivers involved in fatal motor vehicle crashes in Colorado has increased dramatically since the commercialization of medical marijuana in the middle of 2009, according to a study by University of Colorado School of Medicine researchers.
DALLAS, May 15, 2014 — Older migraine sufferers may be more likely to have silent brain injury, according to research published in the American Heart Association’s journal Stroke.
In a new study, people with a history of migraine headaches had double the odds of ischemic silent brain infarction compared to people who said they didn’t have migraines. Silent brain infarction is a brain injury likely caused by a blood clot interrupting blood flow to brain tissue. Sometimes called “silent strokes,” these injuries are symptomless and are a risk factor for future strokes.
The change was clear and it was dramatic: "I went from being property to owning property," a woman in a remote area of Nicaragua told UC Santa Cruz assistant professor of psychology Shelly Grabe.
Grabe wanted to know how the power dynamic between men and women might change when women owned land. More importantly, she wanted to know how the propensity for gender-based violence against women might change.
Chronically homeless, alcohol-dependent individuals might benefit from a new intervention that does not require them to stop or even reduce drinking, according to the results of a preliminary study in Seattle.
Participants in the 12-week pilot program received monthly injections of an anti-craving medication, extended-release naltrexone. They also met regularly with study physicians to set their own goals for treatment and to learn to be safer in their use of alcohol.
HOUSTON – (May 15, 2014) – Children of fathers who are in technical occupations are more likely to have an autism spectrum disorder, according to researchers at The University of Texas Health Science Center at Houston (UTHealth).
The findings will be presented Friday at the International Meeting for Autism Research in Atlanta.
CLEVELAND -- At the 2014 American Association of Neurological Surgeons Annual Meeting, neurosurgical researchers from University Hospitals (UH) Case Medical Center presented results from a small study looking at deep brain electrode implantation as a possible alternative to the traditional WADA test used prior to epilepsy surgery.
PRINCETON, N.J.—Stories about wartime atrocities and torture methods, like waterboarding and beatings, often include justifications – despite whether the rationale is legitimate.
Now, a study by Princeton University's Woodrow Wilson School shows how those justifications actually creep into people's memories of war, excusing the actions of their side. The researchers report in Psychological Science shows how Americans' motivation to remember information that absolves American soldiers of atrocities alters their memories.
