Different psychological status in the two hemispheres of two split-brain patients.

Author information

Department of Psychiatry, Harvard Medical School, McLean Hospital, Belmont, Massachusetts, USA.


Questions of a psychological nature were presented to two split-brain patients from the California series encouraging each hemisphere to respond simultaneously and independently. The responses of both patients indicated that their hemispheres were responding independently. For the first patient, his right hemisphere appeared to be more disturbed than his left by childhood memories of being bullied. The right hemisphere of the second patient seemed to regard himself more positively, but it also seemed to feel more negative emotions such as loneliness and sadness. We discuss the possible significance of the findings.
