ABSTRACT
In this chapter, the similarities and differences existing between hysteria and multiple personality are examined, from a clinical and a cerebral perspective. The underlying affinity linking schizophrenia and hysteria in females, and the evidence indicating that psychopathy in the male and hysteria in the female are corresponding syndromes of the dominant hemisphere modified in their expression by gender, is discussed. Finally, an attempt is made to explain why hysteria and multiple personality are characterized by opposite directionality of relative right/left hemisphere activation, as measured by alpha power suppression.
