Although it is not a very common phenomenon, some people have the ability to be aware of their mental state during dreaming.  This state, called lucid dreaming, is a hybrid between sleep and wakefulness.  Previous studies examining lucid dreaming have shown that the frequency spectrum of electroencephalographic activity during lucid dreaming has features of both rapid eye movement (REM) sleep and wakefulness.  It was also shown...

Just a handful of walnuts per day could improve cognitive function in adults, regardless of their age, ethnicity or gender. That is the main finding of a cross-sectional study published online in the Journal of Nutrition, Health & Aging from researchers in The University of California, led by Dr. Lenore Arab. The study will appear in an upcoming print issue.

Use of the injectable progestin contraceptive depot-medroxyprogesterone acetate (DMPA) may cause an increased risk of acquiring HIV infection among women in sub-Saharan Africa, according to a meta-analysis study published in the journal PLOS Medicine. The findings of the study suggest a pressing need for carrying out randomised control trials to definitively assess the risk of HIV infection associated with hormonal contraception in this...

People with autism spectrum disorder (ASD) have unique individual synchronisation patterns between different parts of the brain compared to a more ‘conformist’ pattern among control individuals without ASD. That is the major finding of a new study published in the journal Nature Neuroscience and led by scientists at the Weizmann Institute and Carnegie Mellon University.

Researchers have persistently sought ways to eavesdrop on neuronal communication.  With each new method our understanding of neuroscience improves, but each comes with drawbacks.  A new study reports the development of a neural interface array (the NeuroGrid) to record brain activity without penetrating the brain surface.
