TL;DR
A hemispheric encoding/retrieval asymmetry model of prefrontal involvement in encoding and retrieval of episodic memory is proposed, which suggests that left and right prefrontal lobes are part of an extensive neuronal network that subserves episodic remembering, but the two prefrontal hemispheres play different roles.
Abstract
Data are reviewed from positron emission tomography studies of encoding and retrieval processes in episodic memory. These data suggest a hemispheric encoding/retrieval asymmetry model of prefrontal involvement in encoding and retrieval of episodic memory. According to this model, the left and right prefrontal lobes are part of an extensive neuronal network that subserves episodic remembering, but the two prefrontal hemispheres play different roles. Left prefrontal cortical regions are differentially more involved in retrieval of information from semantic memory and in simultaneously encoding novel aspects of the retrieved information into episodic memory. Right prefrontal cortical regions, on the other hand, are differentially more involved in episodic memory retrieval.

The use of positron emission tomography to measure regional changes in average blood flow during processing of individual auditory and visual words provides support for multiple, parallel routes between localized sensory-specific, phonological, articulatory and semantic-coding areas.

This effect was observed with college students and amnesic patients, suggesting that word completion performance is mediated by implicit memory for new associations that is independent of explicit recollection.

The structure and functions of the frontal lobes, particularly the prefrontal "silent" portion, have recently again become the subject of intense interest and the availability of solid new findings in experimental animals and human patients and the promise of further discoveries are undoubtedly the basis of this renewed interest.

Support for the general hypothesis that the human brain localizes mental operations of the kind posited by cognitive theories is integrated in the performance of cognitive tasks such as reading comes from studies in mental imagery, timing, and memory.

Willed acts in the two response modalities studied (speaking a word, or lifting a finger) were associated with increased blood flow in the dorsolateral prefrontal cortex (Brodmann area 46) and decreases in blood flow were also associated, but the location of these decreases was modality dependent.

It is concluded that single word comprehension and retrieval activate very different distributed regions of cerebral cortex, with Wernicke's area the only region engaged by both processes and with participation during silent word generation of networks involved in vocalization.

The results provide evidence for selective activation of the human hippocampal region in association with memory function and lead to a suggestion about the neural basis of repetition priming: following presentation of a stimulus, less neural activity is required to process the same stimulus.

Significant cerebral blood flow increases at the junction of the inferior frontal and temporal lobes bilaterally, corresponding to the piriform cortex, and unilaterally, in the right orbitofrontal cortex are reported, indicating that a functional asymmetry exists in the human brain favouring the right Orbitofrontal area in olfaction.

These findings provide direct evidence that, just as the monkey brain, the human lateral frontal cortex is functionally heterogeneous and that comparable anatomical areas underlie similar functions in the two species.
