Abstract
Evoked potentials were summed and averaged for 14 normal subjects during language production tasks. No significant hemispheric asymmetries were obtained. Results show that there is insufficient evidence at this time to conclude that electroencephalographic hemispheric asymmetries are dependent on lateralized language functions. The contaminating influence of the glossokinetic potential on the scalp electroencephalogram is important during language production experiments.
