where is implicit memory stored in the brain?
amygdala
neuropsychology has used imaging techniques such as pet (positron emission tomography) and mri (magnetic resonance imaging) to study brain-injured patients, and has shown that explicit memory relies on the integrity of the medial temporal lobe (rhinal, perirhinal and parahippocampal cortex), the frontal–basal areas and the bilateral functionality of the hippocampus. the amygdala is mainly responsible for the emotional component in the process of information storage (see gazzaniga, 1999; mancia, 2000b, 2004, in press), and can modulate both the encoding and the storage of hippocampal-dependent memories (phelps, 2004). implicit memory, by contrast, is not conscious and concerns data that can be neither remembered nor verbalized. it presides over the learning of various skills: a) priming, which is the ability of an individual to choose an object to which he has previously been exposed subliminally; b) procedural memory, which concerns cognitive and sensorimotor experiences such as motor skills learning, everyday activities, playing instruments or playing certain sports: c) emotive and affective memory, which concerns emotional experiences, as well as the phantasies and defences linked to the first relations of the child with the environment and in particular with the mother.
implicit memory
implicit memories of stimuli do not require conscious recollection of the initial encounter of the stimulus. in regards to olfactory memory, deliberate recollection of an odor experience is not necessary in order for implicit memories of odors to form in the brain. techniques used to study implicit olfactory memory are considered to be applicable to both humans and animals. in tests of implicit memory, memory of a stimulus is shown to be aided by previous exposure to that same stimulus. evidence of the formation of implicit memory is found in tests of habituation, sensitization, perceptual learning and classical conditioning. in olfaction there exists a strong tendency for habituation, which is discussed further in the following paragraph. by evaluating memory performance of tasks involving one of these ‘subsets’ of implicit memory, the effect of previous odor stimulus experience not involving conscious recollection can be measured. further knowledge can be gained about implicit memory of odor through the study of the implications of cognitive deficits. the effects of brain injury on odor memory can be investigated through the use of these implicit memory measures leading to further overall understanding of the brain.
