Abstract
Superconducting Quantum Interference Devices (SQUlDs) can be utilized to construct extremely sensitive magnetometers for brain research. Magnetoencephalographic (MEG) arrays of hundreds of individual SQUID sensors are now in use in over 80 laboratories worldwide. This paper describes the development of four multi-channel MEG arrays of increasing complexity and power at the Low Temperature Laboratory (LTL) under the guidance of Academician Olli Lounasmaa. TWe impact of the availability of these multi-channel MEG arrays on our capacity to characterize the dynamics of both normal and abnormal brain activity is discussed through examples drawn from research conducted at LTL.
