The core of activation-synthesis theory does have significant strength in how it addresses the bizarreness of dreams based on how and why they are formed the theory’s appeal comes from its emphasis on randomness, and so perhaps dreaming cannot be looked at as an evolutionary advantage, it certainly explains how dreams may have developed.
First expressed as the activation-synthesis hypothesis of dreaming (hobson & mccarley 1977), this model proposed the global mapping of brain states to mind states this was the position taken by freud in his famous project for a scientific psychology (1895) but ostensibly abandoned in the interpretation of dreams (1900). Answer to describe the activation-synthesis model of dreaming. Examples: activation-synthesis hypothesis a dream about a komodo dragon actually caused by random firing of neurons in the brain but interpreted by your brain as a dream about komodo dragons.

The 'reward activation model' of sleep and dreams puts emotion back into dreams. Working with robert mccarley, he developed the reciprocal interaction model of sleep cycle control (science, 1975) and the activation-synthesis model of conscious state determination (american journal of psychiatry, 1977) these theories formed the basis of a brain-oriented theory of dreaming radically different from that of freud. C various memories and sensations that are internally generated by the brain that's the answer ^_^.

According to their activation-synthesis model, dreaming is caused physiologically by a “dream state generator,” which is located in the brain stem it is “on . On the other hand, we have this activation synthesis hypothesis that suggest that dreams are simply a part of our brain, the frontal part of the cerebral cortex, that more generalized thinking part of our brain, trying to make sense of these electrical impulses in the brain stem. Hobson and mccarley proposed what they called the activation-synthesis model of dream production, explaining, the primary motivating force for dreaming is not psychological but physiological since the time of occurrence and duration of dreaming sleep are quite constant, suggesting a preprogrammed, neurally determined genesis .

A) primitive sexual and aggressive impulses b) the four stages of nrem sleep so that more rem sleep may occur c) the neurotransmitter called serotonin and the hormone called melatonin d) a hodgepodge of memories and sensations that are internally generated by the brain.

Freud dream theories vs activation synthesis model freud’s dream theory 1990 the unconscious mind he thought that a large part of the mind is non-accessible and is completely hidden.
