Right hemisphere control of visuospatial attention: line-bisection judgments evaluated with high-density electrical mapping and source analysis.

The "line-bisection" task has proven an especially useful clinical tool for assessment of spatial neglect syndrome in neurological patients. Here, we investigated the neural processes involved in performing this task by recording high-density event-related potentials from 128 scalp electrodes in normal observers. We characterized a robust net negative… (More)
