Initial RD-MRE results from intrinsic activation during repeated ON-OFF visual stimulation cycles are presented. Processed probability values from independent t-tests show areas of isolated activity in the region of the visual cortex for certain mechanical parameters, including the real shear modulus and the imaginary bulk modulus. Overlays of these probability value images with co-registered BOLD images show complimentary regions of activation.
