Abstract:
1. A method for measuring brain activity of a subject comprising the steps of: (a) subjecting the subject to at least one first stimulus of interest, measuring brain activity of the subject during a first period of interest, and generating a first brain map for the subject from the measured brain activity; (b) subjecting the subject to at least one second stimulus of interest, measuring brain activity of the subject during a second period of interest, and generating a second brain map for the subject from the measured brain activity; (c) a computer generating a first contrast brain map for the subject by subtracting a parameter of interest of the second brain map from the parameter of interest of the first brain map; (d) a computer generating a second contrast brain map for the subject by subtracting the parameter of interest of the first brain map from the parameter of interest of the second brain map for a plurality of voxels in the maps; and (e) determining if the subject responded to the first or the second stimulus of interest as follows:
