Abstract

A method and system for measuring brain activity by which the signal to noise ratio is increased and image acquisition time is reduced. The method includes obtaining brain oxygenation information using a functional magnetic resonance imaging apparatus, or other apparatus capable of measuring blood flow in the brain. The oxygenation information may then be encoded into a plurality of voxels, which may each be assigned a reference timecourse. The voxels associated with non-gray matter portions of the brain may be isolated and filtered. Each remaining voxel may then be correlated to every other remaining voxel, and the remaining voxels may be displayed as a function of brain activity.
