People born unable to see are readily capable of learning to perceive the shape of the human body through soundscapes that translate images into sound, according to researchers who report their findings in the Cell Press journal Current Biology on March 6. With a little training, soundscapes representing the outlines and silhouettes of bodies cause the brain's visual cortex—and specifically an area dedicated in normally sighted people to processing body shapes—to light up with activity.

INDIANAPOLIS— A study conducted by local high school students and faculty from the Department of Computer and Information Science in the School of Science at Indiana University-Purdue University Indianapolis reveals new information about the motor circuits of the brain that may one day help those developing therapies to treat conditions such as stroke, schizophrenia, spinal cord injury or Alzheimer's disease.
Putnam Valley, NY. (Mar. 6, 2014) – When human umbilical cord blood cells were transplanted into rats that had undergone a simulated myocardial infarction (MI), researchers investigating the long term effects of the transplantation found that left ventricular (LV) heart function in the treated rats was improved over those that did not get the stem cells. The animals were maintained without immunosuppressive therapy.
A randomised placebo-controlled study by the University of Oxford suggests that higher levels of omega-3 DHA, the group of long-chain fatty acids found in algae and seafood, are associated with better sleep. The researchers explored whether 16 weeks of daily 600 mg supplements of algal sources would improve the sleep of 362 children. The children who took part in the study were not selected for sleep problems, but were all struggling readers at a mainstream primary school.
WASHINGTON, D.C., March 6, 2014 ─ Classroom programs designed to improve elementary school students' social and emotional skills can also increase reading and math achievement, even if academic improvement is not a direct goal of the skills building, according to a study to be published this month in American Educational Research Journal (AERJ). The benefit holds true for students across a range of socio-economic backgrounds.
WASHINGTON – Black boys as young as 10 may not be viewed in the same light of childhood innocence as their white peers, but are instead more likely to be mistaken as older, be perceived as guilty and face police violence if accused of a crime, according to new research published by the American Psychological Association.
Though just two of Hirono's 5,418 residents lost their lives in Japan's mega-earthquake and tsunami, a new study shows that the survivors are struggling to keep their sanity.
One year after the quake, Brigham Young University professor Niwako Yamawaki and scholars from Saga University evaluated the mental health of 241 Hirono citizens. More than half of the people evaluated experienced "clinically concerning" symptoms of post-traumatic stress disorder. Two-thirds of the sample reported symptoms of depression.
New Orleans, LA – A model of care developed by the Department of Psychiatry at LSU Health Sciences Center New Orleans School of Medicine to provide mental health services after the Deepwater Horizon Gulf Oil Spill reduced both mental health and general medical symptoms. The novel approach embedded psychiatrists, psychologists, social workers and telemedicine resources into primary care clinics in the most affected areas. This new model can be used in communities at risk for disasters and rural communities with limited mental health resources.
(SACRAMENTO, Calif.) — Atypical development can be detected as early as 12 months of age among the siblings of children with autism spectrum disorder, a study published by researchers with the UC Davis MIND Institute and UCLA has found.
(Boston)--A nationally-recognized sleep expert has published an editorial describing Restless Legs Syndrome (RLS) as a possible biomarker for underlying disease. The editorial appears in the March 5, 2014 issue of Neurology the medical journal of the American Academy of Neurology and was authored by Boston Medical Center neurologist Sanford H. Auerbach, MD.
RLS is a disorder of the nervous system. Patients with RLS have uncomfortable sensations in their legs which lead to an overwhelming urge to move them – most often at night or whenever the patient is resting.
TALLAHASSEE, Fla. — Frequent Facebook users might be sharing more than party pictures, vacation videos and shameless selfies — they also share a greater risk of eating disorders, according to a new study led by Florida State University researchers.
TALLAHASSEE, Fla. — Prenatal exposure to nicotine could manifest as attention deficit hyperactivity disorder in children born a generation later, according to a new study by Florida State University College of Medicine researchers.
Three promising biomarkers being studied to detect Alzheimer's disease in its early stages appear to undergo a surprising shift as patients develop symptoms of dementia, researchers at Washington University School of Medicine in St. Louis report.
GAINESVILLE, Fla. — It may seem normal: As we age, we misplace car keys, or can't remember a name we just learned or a meal we just ordered. But University of Florida researchers say memory trouble doesn't have to be inevitable, and they've found a drug therapy that could potentially reverse this type of memory decline.
(Santa Barbara, Calif.) — On the other side of the cocaine high is the cocaine crash, and understanding how one follows the other can provide insight into the physiological effects of drug abuse. For decades, brain research has focused on the pleasurable effects of cocaine largely by studying the dopamine pathway. But this approach has left many questions unanswered.
