摘要: 目的 通过静息和任务状态脑电功率的比较研究,探讨新生儿脑功能的发展特征。方法 足月新生儿53名,按日龄分三组(第一组1~10 d,第二组11~20 d,第三组21~28 d)。oddball范式听觉刺激下记录任务脑电,进行静息(常规)与任务δ频段脑电功率的比较分析。结果 1) Cz导联第二、三组任务均较静息脑电功率明显增加[二组静息:(281.41±121.73)μV2,任务:(334.42±135.95)μV2;三组静息:(166.39±84.43)μV2,任务:(216.64±89.85)μV2],差异有统计学意义(P<0.05);2) Cz导联三组任务脑电功率发展比较[一组:(203.68±165.96)μV2;二组:(334.42±135.95)μV2;三组:(216.64±89.85)μV2],差异有统计学意义(P<0.05)。结论 新生儿在认知信息加工时脑神经元激活数量上升,使任务脑电功率增强;新生儿δ频段脑电功率随日龄增加而变化,在11~20 d呈最高的特征。接受适当的认知信息,可以促进新生儿脑功能发展。

Abstract: Objective To explore the characteristic of neonatal brain function and development by the comparative research on resting and tasking electroencephalogram(EEG) power. Methods A total of 53 full-term babies were divided into three groups (the first group of 1 to 10 days,the second group of 11~20 days,the third group 21~28 days),tasking EEG was elicited by oddball paradigm auditory stimuli,comparative analysis was carried out between resting (normal) and tasking EEG power in delta frequency band. Results 1)Compared with resting,the increase of tasking EEG power was remarkable in group 2 and 3 at Cz lead [group 2:(281.41±121.73)μV2 vs (334.42±135.95)μV2;group 3:(166.39±84.43)μV2 vs (216.64±89.85)μV2 (P<0.05)];2)Development analysis on the tasking EEG power in three groups at Cz lead [group 1:(203.68±165.96)μV2;group 2:(334.42±135.95)μV2;group3:(216.64±89.85)μV2] showed a significant difference (P<0.05). Conclusion The quantity of neonatal brain activated neurons rised when cognitive information processed,which make the tasking EEG power enhanced;The δ EEG power in newborn changes with age,and reaches the maximum in 11~20 days.Accepting appropriate cognitive information can promote the development of neonatal brain function.
