In future a new magnetic sensor the size of a sugar cube might simplify the measurement of brain activity. In the magnetically shielded room of Physikalisch-Technische Bundesanstalt the sensor has passed an important technical test: Spontaneous as well as stimulated magnetic fields of the brain were detected. This demonstrates the potential of the sensor for medical applications, such as, the investigation of brain currents during cognitive processes with the aim of improving neurological diagnostics.
