DESCRIPTION:Neuropsychological research has highlighted the role of the la
 teral prefrontal cortex in control processes that contribute to memory. Ne
 uroimaging research has generally converged with this idea\, in that activ
 ity in ventrolateral prefrontal regions has been consistently linked with 
 successful long-term memory formation. However\, imaging studies have not 
 consistently identified dorsolateral prefrontal regions as a major contrib
 utor\, and in fact some findings have been argued to show that the dorsola
 teral prefrontal cortex implements processes that are deleterious for memo
 ry formation. In my talk\, I will present evidence from recent neuroimagin
 g studies that support an alternative perspective. Results from these stud
 ies suggest that the dorsolateral prefrontal cortex specifically contribut
 es to successful long-term memory formation through its role in processing
  relationships amongst items in working memory. In contrast\, the results 
 suggest that ventrolateral prefrontal regions play a much more generalized
  role in memory encoding. These results are consistent with hierarchical m
 odels of functional organization in the lateral prefrontal cortex.
