6.6.1 Other cognitive process confounds
We conclude that the extent of the timing “network’ has been significantly over-estimated in the literature. When activity associated with time perception is pitted against that produced by a cognitively more demanding control task, three small regions are active (the confluence of the inferior frontal gyrus and insula bilaterally, a portion of the left supramarginal gyrus and the putamen) and only these can truly be regarded as concerned with time processing.
