title: Functional organisation of the saccadic reference system processing extraretinal signals in humans.
abstract: In order to investigate the neuronal network involved in processing extraretinal signals, functional magnetic resonance imaging (fMRI) was applied to subjects performing the double step saccade paradigm. There, the calculation of the amplitude of the second saccade must rely on extraretinal signals of the first. When compared to a task where both saccades could be performed by means of retinal signals alone, a parieto-frontal cortical network was activated, including lateral intraparietal area, precuneus, insula, inferior frontal gyrus and anterior cingulum.
