The neural substrate of reasoning: an fMRI study

This functional magnetic resonance imaging (fMRI) study aimed at providing insight into the neural substrate of human reasoning ability. We scanned 18 subjects with fMRI, using an event-related design, while they engaged in reasoning tasks based on arguments, which were either valid statements (deductive reasoning) or paradoxes. Participants were required to draw a logical conclusion concerning the accuracy of the syllogisms or the paradoxes. We compared the reasoning tasks with an additional task (control task), in which the subjects had to examine the correctness of the spelling of several arguments. Clusters of significant activation for deductive reasoning were located in left posterior parietal cortex, inferior parietal lobule and bilateral middle frontal gyrus. Clusters of significant activation for paradoxes were located in left superior frontal gyrus, bilateral middle and inferior temporal gyrus and bilateral inferior frontal gyrus. These results indicate that deductive reasoning mainly may activate a left lateralized fronto-parietal brain system, whereas paradoxes may activate a bilateral fronto-temporal brain system.
