Zusammenfassung
The integration of individual features is a fundamental process for the intact perception of a global scene. Disturbance of this process has been found in patients with Bálint's syndrome following bilateral damage of the temporo-parietal cortex. However, the cortical mechanisms underlying grouping processes remain largely unknown. In an event-related fMRI study, we investigated the neural correlates of spatial integration of visual features in healthy subjects. We compared the observed neural activity with the psychophysical performance and tested for attentional modulation of the fMRI responses. The stimuli con…
