Measurement of Neuromagnetic Signals
Biomagnetic measurements are highly sensitive measurements of the magnetic fields generated by a living organism. This method was first utilized to measure the magnetic field of the heart (Albrecht et al., 1989), and has long been used for the registration of evoked magnetic activity of the brain. Measurement of the magnetic fields of the brain in the urban environment is possible with the use of balanced second-order gradiometers during periods with low noise levels. The method is presented here, different ways of employing it are demonstrated, and results are discussed.
