The purpose of this study was to analyze the effects of task similarity on brain activation during commonness discovery. Fourteen pre-service biology teachers participated in this study. This study was designed as block designs for EEG recording. EEG was attached according to international standard electrode method (30 channels). Background EEG for 1 minute, 3 minutes measuring 6 similar tasks, and 6 minutes of break, 6 different tasks were measured for 3 minutes. While the participants discovered commonness, the EEG data were recorded. sLORETA (standardized low resolution brain electromagnetic tomography) was used to analysis the EEG activated during similar and different commonness discovery and to investigate the role of cortical and subcortical structures involved in the similarity of the commonness discover tasks. This study revealed that the precuneus, the cingulate gyrus (BA 31), insula (BA 13), precentral gyrus and middle frontal gyrus (BA 6) were activated during the commonness discovery. Especially, the precentral Gyrus (BA 6 and BA 4) was significantly activated during the different tasks. The results confirmed that commonness discover system of human was related to the frontal lobe, the parietal lobe, and limbic lobe of brain regions.
