A study published in the scientific journal Nature, entitled Formation and suppression of acoustic memories during human sleep, and prepared by members of the Department of Cognitive Research of the University of Paris, discovered evidence that explains how the brain can learn in certain phases of sleep.
There are models such as the hypothesis of active consolidation and the hypothesis of synaptic homeostasis, which aim to explain the relationship between sleep and memory; However, they have not been able to explain how sleep in its different stages is related to learning.
The specialists studied the possibility of learning during sleep, using a method where volunteers had to recognize segments of repetitive sounds embedded in white noise. The volunteers were connected to brain electroencephalogram monitors and the recordings were reproduced while they slept.
The results indicate that during the REM and N2 stages, the unconscious and light sleep stages, respectively, of the sleep, the volunteers were able to recognize the audio extracts, in contrast to the N3 stage, belonging to the deep sleep, where the volunteers could not recognize no sound pattern.
The researchers pointed out that more development is still needed so that these results can have a practical application as a learning method.
