Memory judgments were associated with activation of left frontopolar cortex and parietal areas, whereas preference judgments were associated with activation of medial prefrontal cortex and regions of occipital ...
Dissociable activations within this system implicate a frontopolar involvement in explicit retrieval attempt and right lateral prefrontal cortex involvement in implicit memory expressed in preference judgments ...
Furthermore, we predicted a role for medial temporal lobe structures in response to stimulus novelty (Dolan and Fletcher, 1997) .

A growing body of evidence is converging on a functional organization of the cortical, subcortical, and MTL structures that support the fundamental features of episodic memory in humans and animals. ...
Structures within the MTL, and particularly the hippocampus, have distinct functions in combining information from multiple cortical streams, supporting our ability to encode and retrieve details of events ...

Age-related memory decline is the consequence of multiple biological factors that lead to brain structural and functional change, including gray matter atrophy, white matter injury, and loss of functional ...
We found that GM, WMH, and connectivity between left inferior parietal and medial prefrontal cortex (MPF_LIP) were independently associated with episodic memory performance. ...
While activity in these regions tends to increase during memory task performance, activity in an additional set of brain regions in the prefrontal, parietal, precuneus, posterior cingulate, and medial ...

Short-term (STM) and long-term memory (LTM) have largely been considered as separate brain systems reflecting frontoparietal and medial temporal lobe (MTL) functions, respectively. ...
Whereas thalamo-temporal functional connectivity reflected LTM performance, thalamo-prefrontal functional connectivity specifically predicted STM performance. ...
Such evidence for thalamic atrophy raises the possibility that, in the context of MTL injury, altered integrity of thalamic nuclei, and disruption of their associated respective thalamo-cortical functional ...
