So we can turn the brain stem activity as being activation, and the cerebral cortex trying to understand what's happening as being, as trying to synthesize meaning, and this is very much a hypothesis, and if we put all of those together, we get the activation, synthesis hypothesis which is what this is really called and what i. The activation-synthesis theory is a neurobiological explanation of why we dream the question of why people dream has perplexed philosophers and scientists for thousands of years, but it is only fairly recently in history that researchers have been able to take a closer look at exactly what happens in the.

Book definition:theory developed by harvard university psychiatrists john allan hobson and robert mccarley that dreams begin with random electrical activation coming from the brain stem it answers all the questions about the meaning of dreams by the simple expedient of declaring them meaningless dreams.
In 1977 two biologists hobson and mccarley came up with the activation- synthesis model of dreaming that contested sigmund freud's (1900) theory of dreaming it suggested that dreaming was for biological reasons, dreams were random and had no meaning in this syllabus you are required to learn this biological theory. Activation-synthesis theory hobson and mccarley proposed activation- synthesis theory in 1977 their theory on the function of dreaming came from research that recognized the brain stem was activated during rem sleep hobson and mccarley inferred that during rem sleep, random brain activation produces dreams. Studied 104 dreams obtained from 14 adult ss and quantified the formal aspects of ss' dream experiences by the following categories: movement in dreams, sensation, affect, dream bizarreness, and dream lucidity results provide support for the predictions of the activation-synthesis hypothesis, which postulates that the. Differences freuds theory is less scientific than hobson and mccarleys example, free association (freud) needs to be interpreted, whereas the activation-synthesis theory is brain scanning so has less interpretation, meaning that the activation-synthesis theory is more objective freud's theory is the.
One problem with hobson's original activation-synthesis model was that the theory presumes that all dreams occur in the rem state however, two neuroscientists, james foulkes and john antrobus, have independently shown that long narrative dreams with bizarre elements can happen in non rem.

Despite years of research, the neurological basis for dreams is still not entirely certain, and several theories (including the activation synthesis theory, the long- term memory excitation theory, the continual-activation theory, and others) have been proposed for how and why dreams occur at all, none of which are entirely.
The activation-synthesis theory (hobson & mccarley, 1977) this theory suggests that dreams are what happens when we try to make sense of brain activity during rem freud's ego defence theory (a psychological theory) freud (1900) believed that our conscious experience was just a small part of what actually takes.
