PHILADELPHIA - Amita Sehgal, PhD, a professor of Neuroscience at the Perelman School of Medicine, University of Pennsylvania, describes in Cell a circuit in the brain of fruit flies that controls their daily, rhythmic behavior of rest and activity. The new study also found that the fly version of the human brain protein known as corticotrophin releasing factor (CRF) is a major coordinating molecule in this circuit. Fly CRF, called DH44, is required for rest/activity cycles and is produced in cells that receive input from the clock cells in the fly brain.

LA JOLLA, CA— April 24, 2014 —A team led by scientists at The Scripps Research Institute (TSRI) has deciphered the surprisingly versatile code by which chemical cues help trigger some of the most basic behaviors in mice.
The findings shed light on the evolution of mammalian behaviors—which include human behaviors—and their underlying brain mechanisms.
Culminating an 8 year search, scientists at the RIKEN-MIT Center for Neural Circuit Genetics captured an elusive brain signal underlying memory transfer and, in doing so, pinpointed the first neural circuit for "oops" ? the precise moment when one becomes consciously aware of a self-made mistake and takes corrective action.
Benefits often coexist with the negative and stressful outcomes for parents who have a child born with or later diagnosed with a life-limiting illness, says a recent study led by a researcher at the University of Waterloo.
While the challenges are numerous and life-changing and stress levels high, the vast majority of parents who participated in the Waterloo-led research reported positive outcomes as well, a phenomenon known as posttraumatic growth. The findings appear in the most recent issue of the American Journal of Orthopsychiatry.
Ellen's (not her real name) adoptive parents weren't surprised when the school counselor suggested that she might have attention deficit hyperactivity disorder (ADHD). Several professionals had made this suggestion over the years. Given that homework led to one explosion after another, and that at school Ellen, who is eleven, spent her days jiggling up and down in her seat, unable to concentrate for more than ten minutes, it seemed a reasonable assumption. Yet her parents always felt that ADHD didn't quite capture the extent of Ellen's issues over the years.
CHAMPAIGN, Ill. — It is better to give than to receive – at least if you're an adolescent and you enjoy giving, a new study suggests.
The study found that 15- and 16-year-olds who find pleasure in pro-social activities, such as giving their money to family members, are less likely to become depressed than those who get a bigger thrill from taking risks or keeping the money for themselves.
The researchers detail their findings in the Proceedings of the National Academy of Sciences.
Dust off those Bic ballpoints and college-ruled notebooks — research shows that taking notes by hand is better than taking notes on a laptop for remembering conceptual information over the long term. The findings are published in Psychological Science, a journal of the Association for Psychological Science.
DURHAM, N.C. -- A new study representing the largest study of animal intelligence to-date finds that animals with bigger brains and broader diets have better self-control.
Published this week in the journal Proceedings of the National Academy of Sciences, the study is part of a long history of research aimed at understanding the animal mind. Specifically, why are some species able to do things like make and use tools, read social cues, or even understand basic math, and others aren't?
WASHINGTON -- When the task at hand requires some imagination, taking a walk may lead to more creative thinking than sitting, according to research published by the American Psychological Association.
"Many people anecdotally claim they do their best thinking when walking," said Marily Oppezzo, PhD, of Santa Clara University. "With this study, we finally may be taking a step or two toward discovering why."
Lower weight babies and babies who aren't breastfed or not breastfed for long are at greater risk of developing chronic inflammation and related health problems later in life, according to a new study.
MINNEAPOLIS – People with more years of education may be better able to recover from a traumatic brain injury, according to a study published in the April 23, 2014, online issue of Neurology®, the medical journal of the American Academy of Neurology.
The study examined people with moderate to severe traumatic brain injuries, most of which were from motor vehicle accidents or falls. All were taken to the emergency department and spent time in the hospital after the injury and also for inpatient rehabilitation.
Marijuana use may result in cardiovascular-related complications — even death — among young and middle-aged adults, according to a French study reported in the Journal of the American Heart Association.
Better-educated people appear to be significantly more likely to recover from a moderate to severe traumatic brain injury (TBI), suggesting that a brain's "cognitive reserve" may play a role in helping people get back to their previous lives, new Johns Hopkins research shows.
A Michigan State University researcher is looking to give exercise enthusiasts the extra nudge they need during a workout, and her latest research shows that a cyber buddy can help.
The study, which appears in the Games for Health Journal, is the first to indicate that although a human partner is still a better motivator during exercise, a software-generated partner also can be effective.
While the neurotrophin production dropped away after a couple of months, Professor Housley says ultimately the changes in the hearing nerve may be maintained by the ongoing neural activity generated by the cochlear implant.
