A feedback method for testing the reactivity of the occipital-parietal EEG in selected brain-lesioned patients revealed abnormalities of (a) insufficient reactivity, (b) bilateral differences in reactivity, and (3) asynchrony. These abnormalities were more evident during feedback stimulation than in the baseline conditions. The utility of feedback method for detecting EEG abnormalities rests on the increased stability or decreased "noisy" variation in the EEG during feedback. The EEG becomes more predictable even to the "on-line" human observer. This makes it easier to detect aberrations or deviations from normal effects. Some effects can only be seen with feedback such as the bilateral differences which occur when the left side controls the feedback compared to when the right side controls it. The results show that feedback EEG is a useful tool in clinical research and indicate that a clinical diagnostic test could be developed with more research. However, the feedback EEG method is not yet a proven diagnostic technique.
(a) 反应性不足，(b) 反应性的双侧差异，以及 (c) 不同步。这些异常在反馈刺激期间比在基线条件下更为明显。反馈方法用于检测脑电图异常的效用取决于反馈期间脑电图稳定性的增加或 “噪声” 变化的减少。脑电图甚至对 “在线” 的人类观察者来说也变得更可预测。这使得更容易检测到与正常效应的偏差或偏离。有些效应只有通过反馈才能看到，比如当左侧控制反馈与右侧控制反馈时出现的双侧差异。结果表明，反馈脑电图是临床研究中的一种有用工具，并表明通过更多研究可以开发出一种临床诊断测试。然而，反馈脑电图方法尚未成为一种经过验证的诊断技术。
