Abstract
Studies of neural correlates of working memory functions in the auditory-verbal, visuo-spatial and visuo-object domain suggest a category-specific organization of working memory processes in prefrontal cortex. Here, we used fMRI to explore brain areas that underlie different working memory operations directed to the temporal domain, which so far has been widely neglected. Significant activations related to memory updating and comparison processes were found right-accentuated in prefrontal and lateral premotor cortices. Furthermore, both subvocal rhythm encoding and maintenance enhanced left-lateralized activity in Broca's and supplementary motor area as well as in the sensorimotor cortex. Hemispheric lateralization effects of brain activity during temporal processing tasks may depend on the presence or absence of subvocal rehearsal strategies.
