Reasoning is a cognitive process of inferring conclusions from a given situation. Two different kinds of reasoning, deductive and inductive reasoning, were usually studied separately to examine brain regions essential to each reasoning process. Previous studies lacked a consensus on brain regions in charge, including a debate on whether inferior frontal gyrus is a core region of deductive reasoning or not. Researchers conducted coordinatebased meta-analyses to resolve the issue of inconsistent activation patterns and to compensate for low statistical power from a small sample size. However, they focused on limited types of reasoning and used conventional kernel-based methods like Activation Likelihood Estimation which make no explicit assumption on the model structure. Alternatively, we conducted a coordinate-based meta-analysis study using coordinates from 53 studies, applying an explicit spatial model called Log-Gaussian Cox Process to estimate predictive intensity maps of reasoning processes. This approach enabled us to investigate core regions of each type of reasoning and similarity of their activation pattern. From estimated posterior predictive maps of reasoning processes, we found that prefrontal cortex and posterior parietal cortex are mostly engaged in both deductive and inductive reasoning, but with different activation patterns such as higher activations in left inferior frontal gyrus during deductive reasoning process compared to inductive reasoning. Therefore, we suggest that the two types of reasoning are supported via distinct neural mechanisms.
