On brain's magnetic responses to sensory stimuli.
Magnetoencephalography (MEG) as a tool to study the brain's responses to external stimuli is briefly reviewed. The introduction of multichannel superconducting quantum interference device magnetometers with over 20 sensors is now revolutionizing MEG recordings, and data are starting to accumulate about the functions of different sensory systems. Magnetic evoked responses also can be used in clinical assessment of the integrity of sensory pathways.
