| summary | In the first series of studies (at Johns Hopkins University), working memory (WM) processing of spatial, nonspatial, and verbal information was investigated using functional magnetic resonance imaging (fMRI). The results showed that there is a domain-specific functional organization in the ventral and dorsal prefrontal cortices for WM processing of different kinds of sensory information. However, the representations of objects may be distributed across the ventral and dorsal pathways in terms of verbal, spatial, and semantic information associated with the visual images of objects. In the second series of studies (in the University of Helsinki), speech processing was investigated in order to find out whether linguistic and extralinguistic (voice identity and vocal affect) processes are dissociated and whether there is an interaction between attention and semantic priming for spoken words. The studies were conducted using event-related potential (ERPs) technique and fMRI on neurologically healthy subjects and comatose patients. In the third series of studies (in the University of Nice), ERP and eye-tracking techniques were combined in order to record eye-fixation related potentials (EFRPs) during single fixations while the subjects were performing visual recognition and visual comparative matching tasks. |
