Abstract:
Eye movement behavior is variable, and the brain's oculomotor circuitry may not always function consistently. In a recent fMRI study, Ozyurt and Greenlee (2011) correlated the activation strength of cortical and striatal brain regions with inter- and intraindividual variability in saccade performance. We discuss the design and implications of this study with regard to the differences between inter- and intraindividual variability, and the link between the BOLD signal and oculomotor activity.
