Apparatus and method for quantification of the mapping of the sensory areas of the brain

A system for quantifying the mapping of sensory areas of the brain, the system comprising:

• an electronic processor coupled to a memory, the memory storing instructions that when executed by the electronic processor, cause the electronic processor to
• retrieve sensory functional magnetic resonance imaging (fMRI) data from a subject;
• generate a sensory cortical map based on the sensory fMRI data;
• retrieve brain structure MRI scan data for the subject;
• normalize the sensory cortical map and the brain structural scan to a visual field disk space by conformally mapping the brain structural MRI scan data to a topological disk and smooth the sensory fMRI data on the disk by generating a curve that fits the sensory fMRI data and eliminates noisy outliers
• generate a Beltrami coefficient map comprising a Beltrami coefficient for each of a plurality of locations in the visual field disk space, wherein each Beltrami coefficient is based on a location in the visual field disk space and provides a distortion measure for the location in the disk space.
