AB  - We recorded cortical activity in response to the onset, offset, and frequency 
      change of a pure tone using magnetencephalograms (MEGs) to clarify the 
      physiological significance of N1m relating to the detection of changes. Four 
      interstimulus intervals (ISIs) (0.5, 1.5, 3, and 6 s) were used for each of the 
      three auditory events. Results showed that (i) all three auditory events elicited 
      N1m with a similar topography and similar temporal profile, (ii) the source of 
      N1m was located in the superior temporal gyrus (STG) for all events under all ISI 
      conditions, (iii) the amplitude of the STG activity as a function of the duration 
      of the steady state preceding the change was similar among the three events, and 
      (iv) there was a significant positive correlation in amplitude between on-N1m and 
      off-N1m and between on-N1m and change-N1m. These results suggested that N1m for 
      the three events has a similar physiological significance relating to the 
      detection of changes.
