Document Summary
Limbic lobe": the ring of cerebral tissue surrounding corpus. Limbic system": variably defined, most consider main components as: callosum: cingulate and parahippocampal gyri, hippocampus & fornix, amygdala & stria terminalis, hypothalamus, prefrontal cortex amygdala hippocampus. Consider the experience of receiving your block i exam mark . The big players: cerebral cortex (especially medial and prefrontal regions, amygdala, septal area, hippocampus, hypothalamus. Hippocampus: early ideas about limbic system circuitry and function assigned a central role to the hippocampus, however, the amygdalae and septal area are now felt to be the crucial loci of the emotional brain". 2: although contributing to emotional experience and expression, the main role of the hippocampus appears to be in aspects of learning and memory. Clinical case: h. m: coronal mri of brains of hm (left) and a control subject (right, what can h. m. learn, the star mirror drawing test, # of errors decreases with # of days of practice.
