title: Lower interhemispheric coherence in a case of agenesis of the corpus callosum.
abstract: Interhemispheric coherence and relative power were compared in a patient with total agenesis of the corpus callosum and age and sex matched controls. The patient showed lower interhemispheric coherence than normal controls in F3-F4, C3-C4, and in P3-P4 especially in the higher theta, lower alpha, and beta bands. Differences in relative power were much less marked. These results seem to reflect that interhemispheric connection is degraded because of callosal agenesis.
