[CHANGES OF NORMALIZED SPECTRAL POWER OF ELECTROENCEPHALOGRAM RHYTHMS OF HARD-OF-HEARING CHILDREN AND TEENAGERS].

We showed that a cortical maturation rhythms of people with hard-of-hearing is the subject to the same laws as the background rhythm persons normally hear: with age on the background EEG in the people with hard-of-hearing is a gradual increase in α-rhythm, but still normalized spectral power of the α- rhythm on the background's EEG of teenagers with hard-of-hearing remains below the similar indicators adolescents normally, and greater representation of slow waves. It was found that the background's EEG of teenagers with hard-of-hearing observed moving focus of α-occipital activity in the parietal cortex, which is not observed in the hard-of-hearing children. It can be associated with an increased activity in the limbic system on the background of bark tone in the hard-of-hearing children.
