WebBased on its research and development work, PTB provides a wide range of metrological services. The central task in this context – laid down by law – is to realize and to disseminate the units as accurately as possible. In this way, PTB ensures that uniform measures are used, not only in Germany, but throughout the world. Magnetoencephalography (MEG) is a functional neuroimaging technique for mapping brain activity by recording magnetic fields produced by electrical currents occurring naturally in the brain, using very sensitive magnetometers. Arrays of SQUIDs (superconducting quantum interference … See more MEG signals were first measured by University of Illinois physicist David Cohen in 1968, before the availability of the SQUID, using a copper induction coil as the detector. To reduce the magnetic background noise, … See more Since the magnetic signals emitted by the brain are on the order of a few femtoteslas, shielding from external magnetic signals, including the Earth's magnetic field, … See more In research, MEG's primary use is the measurement of time courses of activity. MEG can resolve events with a precision of 10 milliseconds or faster, while functional magnetic resonance imaging See more • Auditory evoked field • Direct brain interfaces • Electrophysiology See more Synchronized neuronal currents induce weak magnetic fields. The brain's magnetic field, measuring at 10 femtotesla (fT) for cortical activity and 10 fT for the human alpha rhythm, is considerably smaller than the ambient magnetic noise in an urban … See more The inverse problem The challenge posed by MEG is to determine the location of electric activity within the brain from the induced magnetic fields outside the … See more MEG has been in development since the 1960s but has been greatly aided by recent advances in computing algorithms and hardware, and … See more
