Abstract

Objective To compare the cognitive of preterm infants (corrected gestational age) and full-term infants in first week with event related potential (ERP),and to explore the cognitive characteristics of preterm infants. Methods 30 healthy full-term infants (1~7 days) and 15 premature infants (corrected age of 1~7 days) were randomly selected.The auditory event related potential (aERP) was recorded with auditory oddball paradigm,and P2 and N2 wave area on the Fz,Cz lead of the two groups were compared. Results 1)Fz lead,there were significant differences of the P2 and N2 wave area between premature and in full-term infants (t=2.133,P=0.039;t=2.230,P=0.031);2)Cz lead,there were significant differences of the P2 and N2 wave area between premature and in full-term infants (t=2.107,P=0.041;t=2.179,P=0.035). Conclusion Cognitive functions such as voice perception and recognition of preterm infants (corrected gestational age) developed more solely than full-term infants of the same day age in the first week.
