Schizophrenia may alter neuromagnetic representations of attention.
When male paranoid schizophrenic subjects attended to a dichotic oddball task requiring target discrimination, their 100-ms latency left hemisphere magnetic auditory sources did not increase in strength, and their source geometry appeared to be degraded, rather than enhanced, compared with normal control subjects, implicating abnormal processing in the superior temporal gyrus.
