Functional magnetic resonance imaging(fMRI) was used to investigate feature binding of color and shape of images.Reasoning task experiment was designed according to two different features of images.Each task involved feature binding problem.From GLM and BOLD signal analysis,the fMRI result shows: Inductive reasoning as contrast to baseline activated a larger number of brain regions including occipital gyrus,middle temporal gyrus and inferior temporal gyrus,right precentral gyrus superior frontal gyrus and middle frontal gyrus.The regions activated by simple tasks were reduced compared with those by complicated tasks,and the integration of sensory information was related to the right anterior frontal lobe.
