The new functional neuroimaging techniques, PET and functional MRI (fMRI), offer sufficient
experimental flexibility and spatial resolution to explore the functional neuroanatomical …

Brain imaging methods, such as positron emission tomography (PET) and functional
magnetic resonance imaging (fMRI), provide a unique opportunity to study the neurobiology …

The past five years have seen an outpouring of neuroimaging studies of memory—using
both positron emission tomography (PET) and functional magnetic resonance imaging …

Positron emission tomography and functional magnetic resonance imaging studies have
identified brain regions associated with different forms of memory. Working memory has …

The contribution of medial temporal lobe structures to memory is well established. However
recent brain-imaging studies have indicated that frontal cortex may also be involved in …

Evidence is now converging which suggests that, at the area level, working-memory
processes within the dorsolateral and ventrolateral frontal cortices are organised according …

Working memory refers to the short-term retention of information that is no longer accessible
in the environment, and the manipulation of this information, for subsequent use in guiding …

There has long been controversy about the function of the frontal lobes in memory.
Historically, in lesion studies, the frontal lobes were discussed as if they represented a …

This paper briefly reviews two central assumptions of the levels-of-processing framework in
the light of findings from recent PET and fMRI studies: First, to address the suggestion that …

Research on the visual and verbal subsystems of working memory has shown vigorous
development, with PET, fMRI and behavioural data all supporting separate systems, with …
