• Lack of sleep linked to emotional imbalance, imaging study suggests
  It's no secret that the sleep-deprived are usually grumpy, miserable and not much fun to be around, but new research from UC Berkeley using brain-scanning equipment helps explain why. The study, which was published Monday in the journal Current Biology, was the first to use MRI technology to show exactly what areas of the brain are affected by sleep deprivation. Results show a connection between negative thinking and lack of sleep, and while there is still years, if not decades, of research to be done on the subject, the study's authors say it could point to a connection between sleep deprivation and psychiatric disorders like depression and post-traumatic stress syndrome.
