 fMRI guided TMS on cortical eye fields: the frontal but not intraparietal eye fields regulate the coupling between visuo-spatial attention and eye movements. Van Ettinger-Veenstra HM, Huijbers W, Gutteling TP, Vink M, Kenemans JL, Neggers SF. J Neurophysiol. 2009 Oct 7. [Epub ahead of print]

It is well known that parts of a visual scene are prioritized for visual processing, depending on the current situation. How the central nervous system moves this focus of attention across the visual image is largely unknown, although there is substantial evidence that preparation of an action is a key factor. Our results support the view that direct cortico-cortical feedback connections from frontal oculomotor areas to the visual cortex are responsible for the coupling between eye movements and shifts of visuo-spatial attention. Functional magnetic resonance imaging (fMRI) guided transcranial magnetic stimulation (TMS) was applied to the frontal eye fields (FEF) and intraparietal sulcus (IPS).
