Psychotic behavior is typically interpreted as the consequence of soma
to-psychic decompensations of the CNS, a concept within which the vuln
erability-stress-concept plays a central mediating role. The contrary
conceptualization, namely to envisage psychoses from the point of view
of psychosomatics, appears fruitful, if the question is raised, as to
which psychic ''challenges'' lead to an internal destabilization of e
quilibrium states between counteracting neuronal systems. In this cont
ext it can be shown that ''neuro-constructivism'' represents a crucial
model of understanding of the interaction between internal ''censorsh
ip'', reality-hypotheses and sensory data. Psychotic behavior is inter
preted as a decompensation of mechanisms of censorship.
