Why does sleeping on it help? This is the question tackled by new research at the University of Bristol, which reveals how brain activity during sleep sorts through the huge number of experiences we encounter every day, filing only the important information in memory.

New discoveries made by researchers from Bristol’s Centre for Synaptic Plasticity provide further evidence of the benefits of a good night’s sleep and could lead to breakthroughs in how we teach and train.  This is important because bad nights of sleep can lead to impaired mental function.
