Cortical localization of human sustained attention: detection with functional MR using a visual vigilance paradigm.

Abstract

PURPOSE Our goal was to determine whether functional MRI on a standard 1.5 T system can localize activation during a visual vigilance sustained attention task and whether this corresponds to results described in a PET investigation of a similar task. METHOD Sixteen volunteers were studied on a 1.5 T system using a gradient echo technique. A single axial… (More)
