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.
