I have a question about learning and memory. I'm wondering, is the part of the brain responsible for encoding information garnered from external stimuli (especially visual/spatial information) the same part of the brain that encodes memories of fabricated mental imagery? If so, it would be reasonable to assume that if someone found a way to overstimulate the area responsible for spatial memory resulting in increased recall of spatial information, then the same overstimulation of that same area would also increase recall of fantasies. That is my reason for asking the question.
Well, it isn't quite that simple - there is a third 'type of information' I am curious about. Is this the same part of the brain responsible for encoding abstract (formal) information that is derived from sensory experience at that time, such as learning a vocabulary word from a flashcard (which is different from fantasy, which derives its basic material from previous experience, and which is different from visual/spatial, obviously, which is concerned with the concrete stimuli rather than the psychic effects they produce).
By the way, is anyone aware of ways to stimulate these areas more than normal, (chemically, or right after exercise or sleep, perhaps)?
