AbstractPrevious imaging studies have identified many brain regions activated during reasoning, but there are differences among thefindings concerning specific regions engaged in reasoning and the contribution of language areas. Also, little is known aboutthe relation between task complexity and neural activation during reasoning. The present fMRI study investigated brainactivity during complex four-term transitive reasoning with abstract material (determinate or partially indeterminate) andcompared the resulting images to those obtained during a memorization task. The memory condition required subjects tomemorize unrelated elements whereas the reasoning conditions required them to integrate information from premises and toinfer relations between elements. After contrasting the two kinds of reasoning conditions with the memory condition wefound that right prefrontal and bilateral parietal regions are specifically activated during reasoning. We also demonstratedthat different reasoning requirements – the possibility of constructing one (determined reasoning) versus several(undetermined reasoning) models of a situation during task solving – lead to different patterns of brain activity, with higherprefrontal (PFC) activity accompanying undetermined reasoning. We interpret the PFC activity as a reflection of simultaneousmaintenance and manipulation of information in reasoning. These findings provide new evidence that specific forms ofreasoning (abstract and undetermined) demand recruitment of right PFC and hemispheric coordination and lend new supportto the mental model theory of relational reasoning.
