Negative evidence of difference between right- and left-handers in interhemispheric transfer of information.
The present study has been designed to investigate the relationship between handedness and callosal function. Based on the previous finding of a greater anatomical connection between the hemispheres in left-handers than in right-handers and in order to test the possibility of greater functional communication, the efficiency of interhemispheric transfer of information has been measured using a finger localization task. Comparison of two groups of male right-handed and left-handed subjects shows no difference in the efficiency of interhemispheric transfer of information.
