Based On The Neural Mechanisms Of The Fmri Digital Inductive Reasoning

Inductive reasoning is defined as the process of inferring a general rule by observation and analysis of specific instances. The psychological processes of inductive reasoning have been studied extensively, but little is known about its neural basis. To address this issue we scanned 12 subjects with fMRI, while they engaged in simple inductive reasoning tasks and complex inductive reasoning task. We observes activity of frontal lobe,temporal lobe and parietal lobe in both task and a left lateralization. We hypothesize that the left hemisphere plays a critical role in inductive reasoning and is necessary and even sufficient for reasoning, while the right hemisphere is sometimes necessary, but not sufficient. Our result also shows that dorsolateral prefrontal cortex plays a key role in mathematics inductive reasoning, and brain functional network is more activated in complex inductive reasoning task than simple inductive reasoning task. Overall, our finding highlight a strong evidence of the involvement of frontal–temporal system in different levels of inductive reasoning.
