Sleep science has progressed in leaps and bounds over recent decades. However, many difficult questions remain unanswered and its function is far from fully understood. Recent research gives new insight into sleep’s memory processing capabilities. Sleep is as mysterious as it is essential. Characterized by altered consciousness,…

Human brain clocks exposed: Effects of circadian clocks and sleep loss vary across brain regions, new study finds

Ever wondered what happens inside your brain when you stay awake for a day, a night and another day, before you finally go to sleep? In a new study published in the journal Science, a team of researchers from the University of Liege and the University of Surrey have…

Transcranial magnetic stimulation revealed differences between brain activity of people who dream and people who do not dream

Measurements demonstrated that the brain activity of people who dream during NREM sleep, compared to people who do not dream, is closer to the brain activity of awake people. Researchers from Aalto University and the University of Wisconsin utilised a TMS-EEG device, which combines transcranial magnetic stimulation…

Sleepiness and fatigue linked to brain atrophy in cognitively normal elderly

On June 17, 2016, Posted by , In Buzz, By ,,,,,,, , With No Comments

A new study found that normal older adults who experience excessive sleepiness during the day or significant fatigue may have more brain atrophy than expected for their age, particularly in areas of the brain that are more susceptible to aging and Alzheimer’s disease. Results show that subjects…

Mimicking deep sleep brain activity improves memory
