Interfacing mind and brain: A neurocognitive model of recognition memory

2000 Psychophysiology  
A variety of processes contribute to successful recognition memory, some of which can be associated with spatiotemporally distinct event-related potential old0new effects. An early frontal and a subsequent parietal old0new effect are correlated with the familiarity and recollection subcomponents of recognition memory, respectively, whereas a late, postretrieval old0new effect seems to reflect an ensemble of evaluation processes that are set by the task context in which retrieval occurs. Both

The late frontal effect appears to reflect prefrontal cortex activation. A neurophysiologically based model of recognition memory retrieval is presented and it is shown that coupling recognition memory subprocesses with distinct old0new effects allow examination of the time course of the processes that contribute to correct and to illusory memories. In conjunction with event-related functional magnetic resonance imaging activation patterns the brain systems recruited by various aspects of episodic memory retrieval can be identified.
