Functional maps in event-related magnetic field (ERF) during the oddball task showed significant differences in theta, alpha, and beta bands between patients with schizophrenia and control subjects. In the 104 channel, which we arbitrarily chose as an example of the 160 channels (Fig. 1A), a grand average of the time frequency map during the odd ball task showed that beta ERD was increased in patients compared to control groups. However, the grand average of time frequency map at phase-lock during the odd ball task in channel 104 showed that power was not found in either patients or control groups (Fig. 1B, 1C, Fig. 2A, 2B).
