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.
