CORTICAL SOURCES OF MIDDLE LATENCY RESPONSES OF AUDITORY-EVOKED MAGNETIC-FIELD

In the recordings of middle latency responses of auditory evoked magne tic fields in 4 male subjects, we observed distinct components at 11, 19 and 33 ms after click stimulus. Equivalent current dipole sources o f these components were located in the supratemporal auditory cortex, where the earliest component source was found at the most medial site.
