We would like to draw attention to the interesting implications of the existence of common cerebral networks demonstrated in several recent meta-analysis studies on time perception , ,  to current knowledge of higher cognition processes.
In particular we wish to highlight the results of a juxtaposition of two meta-analyses: a multimodal SDM study to identify brain regions involved in neuroimaging studies of response to increasing levels of cognitive difficulty; and an ALE meta-analysis on neuroimaging of time perception . The former meta-analysis comprised 54 fMRI studies undertaken whilst subjects did tasks requiring executive functions. For the latter meta-analysis, there were 35 fMRI studies that looked at different aspects of temporal estimation, such as, interval estimation and discrimination of duration. We then used anatomic cerebral coordinates to carry out an overlapping analysis of statistically significant activation patterns from both meta-analyses.
