Neural mechanisms for timing visual events are spatially selective in real-world coordinates

Nat Neurosci. 2007 Apr;10(4):423-5. doi: 10.1038/nn1874. Epub 2007 Mar 18.

Abstract

It is generally assumed that perceptual events are timed by a centralized supramodal clock. This study challenges this notion in humans by providing clear evidence that visual events of subsecond duration are timed by visual neural mechanisms with spatially circumscribed receptive fields, localized in real-world, rather than retinal, coordinates.
