Evaluating the roles of the inferior frontal gyrus and superior parietal lobule in deductive reasoning: An rTMS study

► TMS was administered on SPL and IFG regions during a deductive reasoning task. ► Bilateral SPL stimulation disrupted abstract and incongruent reasoning performance. ► Left IFG stimulation impaired congruent reasoning performance. ► Right IFG stimulation only impaired incongruent reasoning performance
