Abstract

THE purpose of this study was to extend previous findings of changes in magnetic flux amplitude associated with neuronal currents in the human auditory cortex in response to two-tone stimuli selected from a tone-onset time (TOT) continuum. The results replicated previous findings by indicating a close correspondence between N1m field strength functions and individual perceptual identification curves. In a second experiment event-related fields were recorded in response to two-tone stimuli in which the two sinusoid components always started simultaneously, yet they showed the same energy envelope as the TOT stimuli (amplitude modulated (AM) tokens). The results showed that N1m modulation as a function of TOT could not be accounted for by an effect of AM. The findings suggest that discontinuities in N1m field amplitude functions were the result of interactions between two populations of active neurons each displaying distinct average sound frequency preferences.
