Canadian scientists from Baycrest Medical Center have discovered that just one night of quality sleep can significantly improve the memory of event sequences. This effect persists for more than a year. The team developed an unusual experiment in which participants took a 20-minute audio tour of an art exhibition, after which they were tested five times over a period from one hour to 15 months after the event. In the second stage, volunteers were divided into a sleep group (night in the laboratory with EEG monitoring) and a wakefulness group. The results were confirmed: those who slept remembered the order of events better, even after one year and three months. The discovery confirms that Sleep strengthens connections between events in memory. It also explains why people with dementia lose the chronology of memories, even if they remember her details
