Abstract :
Modern superconducting-quantum-interference-detector (SQUID)-based biomagnetic field measuring devices can detect fields as weak as tens of femtotesla, which are associated with very small ionic currents within the brain. The author reviews the recent emergence of this discipline as a way to look at the brain as well as other ionic activity within the body. Also discussed is the promise of these techniques for passive imaging of electrical activity within the brain
