 One of the most prominent neurotechnologies poised to pose a threat to privacy is Magnetic Resonance Imaging, or MRI. MRI can provide both structural and functional information about a person’s brain with minimal risk and inconvenience. In general, MRI is a tool that allows researchers noninvasively to examine or monitor brain structure and activity, and to correlate that structure or function with behavior. Structural or anatomical MRI provides high-resolution structural images of the brain. While structural imaging in the biosciences is not new, MRI provides much higher resolution and better ability to differentiate tissues than prior techniques such as x-rays or CT scans.
