Partially dissociative role of the left inferior frontal gyrus and left dorsolateral prefrontal cortex in reasoning.

ABSTRACT: Reasoning is the ability to formulate inferences or conclusions from available information. The two major types, deductive and inductive, are thought to rely on distinct cognitive mechanisms and recruit separate brain areas. Neuroimaging studies yield mixed results; some found the left inferior frontal gyrus (IFG) activations for deductive reasoning and the left dorsolateral prefrontal cortex (DLPFC) for inductive reasoning. This assumption was put to the test in the present study. In two double-blinded, sham-controlled experiments, high-definition transcranial direct current stimulation (HD-tDCS) was used to systematically explore the left IFG's and DLPFC's causal role in deductive and inductive reasoning. Participants with no formal training in logic judged deductive and inductive argume
