Dissociating Memory Retrieval Processes Using fMRI Evidence that Priming Does Not Support Recognition Memory
We employed event-related fMRI to constrain cognitive accounts of memory retrieval. Studies of explicit retrieval reveal that lateral and medial parietal, dorsal middle frontal gyrus, and anterior prefrontal cortex respond more for studied than new words, reflecting a correlate of "retrieval success." Studies of implicit memory suggest left temporal cortex, ventral and dorsal inferior frontal g...
متن کاملMemory: Dissociating multiple memory processes
Memory depends upon a network of interconnected and functionally related cortical and subcortical areas including, at the very least, the prefrontal cortex and the medial temporal lobe structures. Evidence is now emerging to relate these neuroanatomical regions to specific aspects of mnemonic processing.
متن کاملDissociating state and item components of recognition memory using fMRI.
Cognitive functions such as memory retrieval involve a combination of state- and item-related processes. State-related processes are sustained throughout a task (e.g., "retrieval mode" associated with ongoing goals), whereas item-related processes are transient and allied to individual stimuli (e.g., "retrieval success" associated with the recovery of information from memory). The present study...
متن کاملFurther Dissociating the Processes Involved in Recognition Memory: An fMRI Study
Based on an event-related potential study by Rugg et al. [Dissociation of the neural correlates of implicit and explicit memory. Nature, 392, 595-598, 1998], we attempted to isolate the hemodynamic correlates of recollection, familiarity, and implicit memory within a single verbal recognition memory task using event-related fMRI. Words were randomly cued for either deep or shallow processing, a...
متن کاملDissociating semantic and phonological maintenance using fMRI.
Functional magnetic resonance imaging (fMRI) distinguished regions of neural activity associated with active maintenance of semantic and phonological information. Subjects saw a single word for 2 sec, and following a 10-sec delay, made a judgment about that word. In the semantic task, subjects focused on the meaning of the word and decided whether a second word was synonymous with it. In the ph...
