Williams syndrome (WS) is a rare genetic disorder that results in profound spatial cognitive deficits. Several behavioral studies have showed that point-light walker (PLW) perception is intact in children and adults with WS; however, the neural responses underlying PLW perception in adults with WS have not been fully investigated. In this study,we studied an adult with WS by magnetoencephalography. We introduced a novel experimental technique to extract a neuromagnetic response relating to PLW perception, and then evaluated how this response differed from that in normal adults. The peak amplitude and latency of neuromagnetic responses were within 2 SD of the means among normal adults.
威廉姆斯综合征（WS）是一种罕见的遗传性疾病，会导致严重的空间认知缺陷。多项行为研究表明，患有WS的儿童和成人对光点步行者（PLW）的感知是正常的；然而，WS成年患者中PLW感知背后的神经反应尚未得到充分研究。在本研究中，我们通过脑磁图对一名成年WS患者进行了研究。我们引入了一种新颖的实验技术来提取与PLW感知相关的神经磁反应，然后评估该反应与正常成年人的反应有何不同。神经磁反应的峰值幅度和潜伏期在正常成年人平均值的2个标准差范围内。
