[Interhemispheric functional relationships in chronic alcoholism].

The authors examined the functional interhemispheric relations in chronic alcoholics by registering evoked potentials. It was found that in those subjects the information processing was considerably delayed in both hemispheres, however, this delay was more marked in the right hemisphere. In this hemisphere also the magnitude of the evoked response was lowered, this lowering being statistically significant. On the basis of the prolongation of the latent period and the diminution of the amplitude of the P300 wave in the right hemisphere the authors conclude that in chronic alcoholics the interhemispheric relations are changed due to an impairment of the right hemisphere functioning.
