Abstract:

Human being preserves some elementary concept of number innately. The brain basis of cardinal number was founded at the places around intraparietal sulcus. If these brain areas were damaged or impaired in development, it would result in dyscalculia or some other inabilities on numerical cognition. However, the ordinal number was mainly represented in frontal and temporal lobes. Does the notation effect exist in the processing of ordinal number? What is the cultural difference of ordinal number and its neural correlates? These questions need further exploration

Key words: ordinal number, prefrontal lobe, temporal lobe, cultural difference
