A new study by scientists from the UK Dementia Research Institute (UK DRI) at Imperial College London has shown that the brain’s ability to clear itself of toxins slows down during sleep. By measuring the clearance of toxins and fluid movement in the brains of mice, the researchers found that these processes slowed during sleep and under anesthesia.
Scientists used a fluorescent dye and watched it rapidly move from one part of the brain to another and be cleared from the brain. It turned out that the elimination rate of this dye was reduced by approximately 30% in sleeping mice and 50% in anesthetized mice compared to awake mice.
The results of the research were published in the journal Nature Neuroscience.
