Youth with mild spastic cerebral palsy (n = 14) and a peer control group were compared on an oddball paradigm. Here, visual stimuli were presented with low and high probability and participants were instructed to count in silence the number of rare stimuli. The infrequent stimulus typically elicits an enhanced frontal central N2 and a centroparietal P300 event-related brain potential, reflecting orientation and evaluation of stimulus novelty. No differences in latency and amplitude of the N2-P300 complex were found between the 2 groups, indicating that some fundamental attention processes are intact in youth with mild spastic cerebral palsy.
在一个oddball范式中,对患有轻度痉挛性脑瘫的青少年(n = 14)和一个同龄对照组进行了比较。在此范式中,以低概率和高概率呈现视觉刺激,并指示参与者安静地数出罕见刺激的数量。罕见刺激通常会引发增强的额中央N2和中央顶叶P300事件相关脑电位,反映对刺激新颖性的定向和评估。两组之间在N2 - P300复合波的潜伏期和波幅上未发现差异,这表明患有轻度痉挛性脑瘫的青少年的一些基本注意力过程是完整的。
