• Patterns of brain swelling may explain susceptibility of children to cerebral malaria

  10-03-2016 20:37
  Brain swelling is a strong predictor of death in children with cerebral malaria (a severe form of the disease where parasites have accumulated in brain vessels), and also in mice with experimental cerebral malaria. A high-resolution whole brain imaging analysis of swelling in ECM suggests that cerebral malaria depends on the permissive environment in a specific brain area.

• Scientists watch activity of newborn brain cells in mice; reveal they are required for memory

  10-03-2016 18:49
  Neuroscientists have described the activity of newly generated brain cells in awake mice -- a process known as adult neurogenesis -- and revealed the critical role these cells play in forming memories. The new research also offers clues as to what happens when the memory-encoding process goes awry.

• Grid cells' role in human imagination revealed

  10-03-2016 18:49
  Evidence of grid cell activity has been seen in healthy volunteers asked to imagine moving through an environment. The study used fMRI scans to detect brain activity consistent with grid cell activity in the entorhinal cortex, an important 'hub' for navigation and memory. The entorhinal cortex is one of the first areas affected by Alzheimer's disease, so the latest research could help to explain why people with Alzheimer's can have problems imagining as well as remembering things.

• Blame your noisy brain for misses and fumbles

  10-03-2016 18:49
  No matter how much we practice a given movement, it will still be imperfect. The reason for this frustration, according to a new study by neuroscientists, is in how we sense the world. A given individual neuron varies in its activity even when we see exactly the same scene, producing a certain kind of brain noise that affects our responding movements.

• Oxytocin can improve compassion in people with symptoms of PTSD

  10-03-2016 17:24
  Oxytocin -- "the love hormone" -- may enhance compassion of people suffering from symptoms of post-traumatic stress disorder (PTSD), according to new study. Compassion is pro-social motivation to help others who are in distress. It is an outcome of emotional of empathy -- the ability to recognize the feelings of others, and cognitive empathy -- the ability to understand what another person feels and think.

• Researchers optimize methods to study neurons during motor activity

  10-03-2016 17:19
  Researchers have optimized the techniques for studying motor learning in order to repeatedly assess the activity of neurons for days, weeks, or even months. These sophisticated approaches allow the further characterization of the neurons that are continuously engaged during motor activity and normal behavior.

• Do we need sex tech to 'demystify' the female orgasm? | Girl on the Net

  10-03-2016 08:15
  
  The female orgasm is often viewed as “mysterious”, and this isn’t helpful. Technology may help, but it’s not a complete solutionNo one asks sex writers to ‘demystify’ the male orgasm, or commissions tips for straight women on how they can ‘guarantee’ their man makes it to that all-important climax. In fact, so odd does that word ‘demystify’ sound when applied to a guy’s orgasm, when I checked Google to see if anyone had covered it
