[Evaluation of central speech disorders using objective criteria: a psychophysiologic contribution to the discussion of the neural plasticity hypothesis].
Examinations of aphasic patients by using cognitive tasks were based on the hypothesis that semantically evoked potentials correlate to the processing of information in the different speech processing of information in the different speech processing areas. It was found that patients with Broca aphasia generated synchronization potentials in the Wernicke area in contrast to Wernicke patients. We suppose a correlation between the timing in sensorial speech processing areas and the generation of synchronization potentials.
