There is strong evidence that behavioral events alter neuro-chemical function and that altered neurochemical function can change behavior.  Responsible are certain chemical substances called neuroregulators, which act as messengers in the nervous system.  In susceptible individuals, certain psychological states may influence changes in neuroregulatory activity, which may then produce changes leading to psychotic symptoms, perhaps by the establishment of a biochemical pattern.  Some behaviors, normal or otherwise, may become increasingly likely or strong in response to repeated stimulation – electrical, chemical or psychological – until they become self-perpetuating, no longer dependent on the original stimuli.  For instance, the effects of some important early experiences in life may be reflected in biochemical changes that alter communication between neuronal units later in life.  Certain stressors do seem to alter the way in which a neuroregulator functions at a synapse with potential alterations in its effect on receptors.
