Polymodal semantic processing of actions in the left inferior frontal lobe

While neuronal correlates of object utilization parameters have been examined thoroughly, few studies have specifically addressed the neurobiological substrates of knowledge about object function. Aim of the present study was therefore to assess supramodal semantic processes that are common to the processing of visually and verbal-acoustically presented actions with familar man-made objects. We hypothesized that there exist common mechanisms involved in the semantic processing of actions presented via different sensory modalities. 18 healthy male subjects participated in an event-related fMRI study. We used a 2…
