Abstract: Scalar timing model (STM) was taken as a framework with analyzing many references about temporal cognition neural mechanism.Taking the reference of the results of present cognitive neuroscience studies, it could be concluded that the neural correlates of internal clock were cerebellum, basal ganglia, prefrontal cortex, presupplementary motor area and inferior parietal lobe, etc.; the neural correlates of duration memory period were basal ganglia, dorsolateral prefrontal cortex, right inferior prefrontal cortex and lateral premotor, etc.; the neural correlates of duration comparison period were basal ganglia, anterior cingulate cortex, and superior temporal cortex, etc. In addition, the characteristic of scalar of timing was demonstrated on the view of neural mechanism, and further study about the confirmability of study results, the limits of research methods, and applicability of STM were discussed

Key words: Scalar timing model, temporal cognition, neural mechanism
