• Exercise may be associated with reduced disease activity in children with MS

  12-08-2015 22:59
  Children with multiple sclerosis who exercise regularly may have a less active disease. For the study, 31 children with MS and 79 who had experienced a single inflammatory neurologic event were given questionnaires about tiredness, depression and how often they exercised. Of those, 60 were also given MRI brain scans to measure brain volume and the amount and type of MS lesions they had.

• Cardiorespiratory fitness linked to thinner gray matter and better math skills in kids

  12-08-2015 21:12
  A new study reveals that 9- and 10-year-old children who are aerobically fit tend to have significantly thinner gray matter and do better on math tests than their 'lower-fit' peers.

• Scientists uncover a difference between the sexes

  12-08-2015 19:56
  Many brain disorders vary between the sexes, but how biology and culture contribute to these differences has been unclear. Now neuroscientists have found an intrinsic biological difference between males and females in the molecular regulation of synapses in the hippocampus, a brain region involved in learning and memory, responses to stress and epilepsy. This finding provides a scientific reason to believe that female and male brains may respond differently to drugs targeting certain synaptic pa

• Rapid eye movements in sleep reset dream 'snapshots'

  12-08-2015 19:19
  Rapid Eye Movement (REM) sleep, the period in which we experience vivid dreams, was discovered by scientists in the 1950s. A new study based on rare neuronal data offers the first scientific evidence of the link between rapid eye movement, dream images, and accelerated brain activity.

• Science-backed brain game eases distraction, anxiety

  12-08-2015 19:14
  Researchers have created a surprisingly simple yet targeted brain game that reduces anxiety by helping people focus in an increasingly distracting world. There are a plethora of "brain-training" games on the market, a researcher noted, but they are highly controversial and offer no independent scientific proof they help sharpen focus, let alone reduce anxiety.

• Brain plasticity after vision loss has an 'on-off switch'

  12-08-2015 16:37
  A molecular on-off switch that controls how a mouse brain responds to vision loss has been discovered by biologists. When the switch is on, the loss of sight in one eye will be compensated by the other eye, but also by tactile input from the whiskers. When the switch is off, only the other eye will take over. These findings may help improve patient susceptibility to sensory prosthetics such as cochlear implants or bionic eyes.

• Study Examines Top High School Students' Stress, Coping Mechanisms

  12-08-2015 05:58 via feeds.socialpsychology.org
  Source: ScienceDailyThere is growing awareness that many subgroups of youth experience high levels of chronic stress, to the extent it impedes their abilities to succeed academically, compromises their mental health functioning, and fosters risk behavior. Furthermore, this chronic stress appears to persist into the college years, and researchers warns it may contribute to academic disengagement and mental health problems among emerging adults.

• "Brain Signature" That Predicts Human Emotions Discovered

  12-08-2015 05:58 via feeds.socialpsychology.org
  Source: ScienceDailyResearchers have discovered a way to predict human emotions based on brain activity. The study is unusual because of its accuracy -- more than 90 percent -- and the large number of participants who reflect the general adult population rather than just college students. The findings could help in diagnosing and treating a range of mental and physical health conditions.
