Abstract(in English) | In this study we compared the temporal recovery function of auditory evoked magnetic fields in schizophrenic patients and in normal volunteers using paired-stimulus paradigm. Tone bursts of 10 msec duration were delivered in pairs to both ears at interpair intervals of 1.4 - 1.6 sec. Stimulus onset asynchrony (SCA) within the pair was either 50, 70, 100, 150, 200, 300, 500 or 700 msec, all intervals being presented randomly. Magnetic responses were recorded with a 204-channel whole-head neuromagnetorneter and the channel which showed maximal P50m - N100m was selected for analysis. The recovery curves of P50m showed significant difference between the two groups, not only at 500 msec but also at 150 msec in SOA. |
