| Abstract(in English) | When presented with a novel tool, we need to reason out the functions of the tool in order to use it properly. We do this by a process called "mechanical problem solving" or "mechanical reasoning." Recent studies have reported that the supramarginal gyms (SMG) is involved in mechanical problem solving, but the details remain unclear. This study used healthy volunteers in two fMRI experiments to identify the relevant brain cortexes involved in mechanical problem solving, in order to determine the underlying brain mechanisms. In the first experiment, where participants performed tasks about tool use, the SMG was activated when the function of a tool was inappropriate for a particular task. In the second experiment, where participants performed tasks involving retrieval of procedures for manipulating objects, the inferior frontal gyms (IFG) and SMG were activated when imaging the manipulation of objects in a predetermined procedure. Mechanical problem solving appeared to include the function of understanding the interactions between objects, which is associated with the SMG, and the function of imaging the manipulation in a predetermined procedure, which is associated with IFG. |
