Abstract

F errarelli et al (page 766) used transcranial magnetic stimulation with simultaneous high-density electroencephalographic recordings to show a slowing of the main oscillatory frequency (natural frequency) of frontal cortical areas in schizophrenic patients. The prefrontal natural frequency of schizophrenic patients was slower than in any control subject. Moreover, it was negatively correlated with positive Positive and Negative Syndrome Scale scores and reaction time in a word memory task.
