Researchers are using this powerful tool to better understand how the brain reconstitutes consciousness and cognition after disruptions caused by sleep, medical procedures requiring anesthesia, and neurological dysfunctions such as coma. In a new study published in the journal eLife, a team led by anesthesiologists George Mashour, M.D., Ph.D. of Uni...

Sleep scientists assessed how effective caffeine was in counteracting the negative effects of sleep deprivation on cognition.

 E-Mail A new study from the Institute of Psychiatry, Psychology and Neuroscience (IoPPN) at King's College London has established that Intermittent Fasting (IF) is an effective means of improving long term memory retention and generating new adult hippocampal neurons in mice, in what the researchers hope has the potential to slow the advance of cognitive decline in older people. The study, published today in Molecular Biology, found that a calorie restricted diet via every other day fasting was an effective means of promoting Klotho gene expression in mice. Klotho, which is often referred ...

Publishing today, in the Journal of Neuroscience, lead author Dr Sukhbinder Kumar, Newcastle University Research Fellow in the Biosciences Institute said: "Our findings indicate that for people with misophonia there is abnormal communication betwe...
