ABSTRACT The aim of this paper was introduction of preliminary study of late auditory evoked potentials P300 and MMN insome central communication process disorders. The investigations were performed in the group of three children with development dysphasia and pseudobulbar dyzarthria. The registration of endogenic late cognitive potentials was performed using the alternate application of stimulus of pure tones 1 and 2 kHz, and logatoms (da)-(ga). In all patients the normal hearing threshold and the unilateral disturbances in registration of P300 and mismatch negativity (MMN) were found.
