Health & Body - Reverse learning: why our brains dream to discard memories
Health & Body · 0:38
In 1983, researchers Crick and Mitchison published their reverse learning theory of dreams in the journal Nature. Likening the dreaming brain to an offline computer during rapid eye movement sleep, they proposed that dreaming helps the mind unlearn. According to the model, the cortex receives vast daily information and must wipe out parasitic thoughts to preserve memory organization. Subcortical impulses bombard cortical networks to dampen unwanted connections, meaning the brain dreams to discard extraneous material.
