'Waves' of neural activity give new clues about Alzheimer's
While unconscious during deep sleep, millions of neurons' activity travels across the cerebral cortex. This phenomenon, known as slow waves, is related to the consolidation of memory. The European project called SloW Dyn, led by Spanish scientists, has now revealed anomalies in this activity in mice displaying a decline similar to Alzheimer's. (2017-09-05)
