Studies using functional magnetic resonance imaging (fMRI) have revealed that various number-processing tasks activate a fronto-parietal network in educated adults. However, it is uncertain how a person's number processing system might be affected by their level of mathematical proficiency. We used fMRI to investigate whether Boolean calculation abilities arise from more basic number processing. The...
Using event-related functional magnetic resonance imaging (fMRI) and the Ebbinghaus paradigm, we investigated the effect of memory in parietal cortex activity. In the course of one week, participants learned Boolean arithmetic tasks and were asked to master them perfectly. We measured cerebral activation with fMRI while healthy volunteers had learned and practiced Boolean rules on day 1 (i.e., labile...
