Telemetered EEG and ECG were recorded from 18 Down's syndrome children (5;6--11 years) during rest, a visuomotor and a cognitive test, exploration and play. Simultaneously the behaviour was observed and recorded. In comparison with normal children (3;9--5;5 y. resp. 5;6--7;6 y.) the Down's syndrome children showed a low degree of motor activity, reduced attention and exploration and little variation of heart rate in relation to test difficulty. The main findings in the EEG (parieto-occipital recording) were a low amount and a small variability of alpha waves and a high amount of beta waves. This EEG phenomenon which is obviously not due to high activation is discussed with regard to possible connections with defective neurophysiological mechanisms of attention.
对18名唐氏综合征儿童（5岁6个月至11岁）在休息、视觉运动和认知测试、探索及玩耍期间进行了遥测脑电图和心电图记录。同时对其行为进行了观察和记录。与正常儿童（分别为3岁9个月至5岁5个月及5岁6个月至7岁6个月）相比，唐氏综合征儿童的运动活动程度较低，注意力和探索能力下降，且心率随测试难度的变化较小。脑电图（顶枕部记录）的主要发现是α波数量少、变异性小以及β波数量多。这种显然并非由高度激活引起的脑电图现象，就其与注意力的神经生理机制缺陷可能存在的联系进行了讨论。
