A new sensor measures weak magnetic signals in the brain, which has the potential to increase the understanding of connectivity in the brain and detect signs of traumatic brain injury, dementia, and schizophrenia. The optically pumped magnetometer (OPM) sensor uses polarized light to detect changes in the orientation of the spin of atoms when they are exposed to a magnetic field.
