Magnetoencephalographic (MEG) auditory evoked fields (EF) were recorded from 12 normal adult subjects over both hemispheres on two separate occasions at least one week apart using a seven-channel second-order gradiometer. Stimuli were computer-generated at 25-msec duration, 1 kHz tone pips. Responses to 100 stimuli were averaged, and source estimates with(More)
An interactive graphics simulation program for the RF-SQUID (superconducting quantum interference device) has been developed. The program allows the user to graphically observe fluxoid quantization, the amplitude-limiting effect of the tank circuit voltage due to the SQUID coupling, the periodic voltage response due to an external DC flux, the tank circuit(More)
