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.
我们发现,听力障碍者的皮质成熟节律遵循与正常听力者背景节律相同的规律:随着年龄增长,听力障碍者的背景脑电图中α节律逐渐增加,但听力障碍青少年背景脑电图上α节律的频谱功率仍低于正常青少年的类似指标,且慢波占比更大。研究发现,听力障碍青少年的背景脑电图显示枕叶α活动焦点向顶叶皮质移动,而听力障碍儿童未观察到这种情况。这可能与听力障碍儿童大脑皮层音调背景下边缘系统活动增加有关。
