Abstract

Completely non-invasive, real time (at a frame resolution of a second or less) tomographic movies of dynamic human visual system and motor system activity are demonstrated. These images are based on single shot functional magnetic resonance imaging (MRI) techniques sensitive to changes in either cerebral blood flow (CBF) or blood oxygenation. Given the close correspondence in both space and time between cerebral hemodynamic changes and neuronal activation, these data provide the highest spatial and temporal resolution tomographic maps of human brain activity reported to date.
