Description

Activation-Synthesis Theory

Hobson and McCarley's activation-synthesis theory suggests that dreams are the result of the brain's attempt to make sense of random neural activity during sleep. It includes concepts such as the blockade of sensory input and motor output, and the synthesis of this activity in the cerebral cortex.
