Schizophrenic symptoms: a theory based on a neurophysiological model

Under normal conditions, just a few mental subunits are simultaneously at a conscious level according to a previously presented model. The present paper explains how a somewhat increased number of simultaneously appearing subunits can cause the positive schizophrenic symptoms (thought disturbances, hallucinations, etc). Negative schizophrenic symptoms can develop when too few mental subunits are appearing at a time. Neuroleptic drugs are proposed to act by reducing the number of simultaneously appearing subunits.
