Students teach science concepts to a multi-agent intelligent system , Betty 's Brain , using concept map representations with a visual interface . Dopamine is commonly associated with the ' pleasure system ' of the brain , providing feelings of enjoyment and reinforcement to motivate us to do , or continue doing , certain activities . Exposure to high levels of glucocorticoids causes a down regulation of glucocorticoid receptor levels in various regions of the brain , including the hippocampus , hypothalamus and amygdala ( Sapolsky et al , 1984 ) . Idomeneus speared Erymas in the mouth ; the bronze point of the spear went clean through it beneath the brain , crashing in among the white bones and smashing them up .
