Dream report following commissurotomy.


This paper addresses the question of right hemisphere involvement in the visual components of dreaming. The rationale derives from an observed relation between reports of visual agnosia accompanied by dream cessation and the literature on right hemisphere specialization for visuo-spatial processes. All night sleep EEGs were recorded from subjects with partial or complete section of the corpus callosum and anterior commissure. Upon entering a EEG-, EOG- and EMG-defined REM episode, the subjects were awakened and questioned about dream content. All subjects examined in this fashion were able to recount some visual dream content. This result fails to support any notion of selective right hemisphere visual dream mediation.
