AP PSYCHOLOGY

Detailed explanation-1: -To summarize, the activation-synthesis theory essentially made three key assumptions: High levels of activity in the brainstem are necessary for dreaming to take place. Activation in these areas of the brain results in REM sleep and dreaming, and by corollary, all dreaming takes place during REM sleep.

Detailed explanation-2: -Activation-Synthesis Theory of Dreaming The main idea behind activation-synthesis theory is that dreams are just the brain’s efforts to make sense out of meaningless patterns of firing in the brain as we sleep. Certain circuits in the brain become activated during REM sleep.

Detailed explanation-3: -The Activation-Synthesis Theory, also called the neural activation theory, is a neurobiological approach to explain why humans have dreams. It states that a dream is the cerebral cortex processing nerve impulses being sent from the body to the brain stem into something that makes sense.

Detailed explanation-4: -Physiological theories claim that dreams are a product of processes in the body that the brain interprets when we sleep.

Detailed explanation-5: -We suggest that the brain combats neuroplastic incursions into the visual system by keeping the occipital cortex active at night. We term this the defensive activation theory. In this view, REM sleep exists to keep the visual cortex from being taken over by neighboring cortical areas.
