Dichotic Listening in Man after Section of Neocortical Commissures
Doreen Kimura’s modification of the dichotic listening technique of Broadbent for use as a means of studying the functions of the individual hemispheres represents a major contribution to the study of the human brain, since it is completely harmless and can be used in normals as well as patients. Mr. Robert Sparks and I made the first study of dichotic listening in a patient with a callosal section, whom we were able to study through the kindness of Dr. Joseph Bogen, Dr. Roger Sperry and Dr. Michael Gazzaniga. Our study was based on only one patient, and we were therefore pleased that a subsequent study of a larger series of callosally sectioned patients by Milner et at. (1968) confirmed our findings.
