Location of somatosensory-evoked dipoles studied by a SQUID system in a superconducting magnetic shield

A whole-head SQUID system in a superconducting magnetic shield was used to study somatosensory response experimentally. The low-noise data obtained by the 64-channel SQUID system in the superconducting magnetic shield allowed a reliable application of the MUSIC (multiple signal classification) estimation of dipoles.
