Dreams may help us learn

Weird dreams may help us learn from our experiences, a new research suggests.

Sleep and dreams are important for learning and memory, and a disturbed night may impair cognition.

Non-REM sleep duplicates sensory inputs we receive while awake, whereas REM sleep produces vivid dreams from spontaneous brain activity.

To study how each phase influences learning, researchers created simulations of the cerebral cortex, incorporating unusualness in artificial dreams using Generative Adversarial Networks 

To assess the model's effectiveness, researchers utilised a classifier to see how readily item identities can be inferred from cortical representations.

Senior author and team leader Dr. Jakob Jordan of the University of Bern remarked, “Non-REM and REM dreams grow more lifelike as our model learns.”
