Research on the brain, sleep, memory and the human “neural compass”.

Although it is widely believed that a good night’s sleep helps in removing toxins from the brain, a recent study found that this explanation is not valid. Researchers used a fluorescent dye to study the brains of mice and discovered that the clearance factor and fluid flow in the brain were much lower during sleep (30%) and anesthesia (50%) compared to regular activity. Scientists believe that these findings may also apply to humans and could have implications for dementia research.

Scientists from the University of Birmingham and the Ludwig-Maximilian University of Munich are conducting motion-tracking experiments to understand the human neural compass. This research aims to fill gaps in our knowledge about this crucial neural network, which could significantly advance our understanding of diseases such as Parkinson’s and Alzheimer’s, which often involve impaired navigation and orientation.

UCLA Health researchers have identified a mechanism that creates memories while reducing metabolic costs, even during sleep. This efficient memory, called working memory, occurs in the brain’s region crucial for learning and memory, and where Alzheimer’s disease begins. Using a specially prepared “mathematical microscope,” experts revealed the inner workings of the neurons that create memory. Working memory allows a person to remember specific information for a short period while dealing with other tasks.
