What does the sleeping brain think about?

(Universit é de Gen è ve) Using an artificial intelligence approach capable of decoding brain activity during sleep, scientists (UNIGE) were able to glimpse what we think about when we are asleep.

Indeed, the brain can evaluate all of these memories in order to retain only the most useful ones.
