To assess the spatio-temporal structure of discontinuous EEG tracing in mature and immature newborns, we analysed mean spectral power in frequency bands between 0.8 and 16.8 Hz in 6 full-term newborns and 7 premature newborns < 32 weeks of conceptional age. The most striking results showed a significantly higher mean spectral power for the first half of bursts than for the second half recorded in > 2.8-14.8 Hz frequency bands. This pattern was more pronounced in premature than in full-term newborns. No clear differences were observed in comparisons between the first and the second half of the interburst periods. In addition, as far as mid and high frequency band spectra were considered, the mean spectral power of burst was, in both groups, higher in the right as compared to the left occipital regions.
为评估足月和未足月新生儿间断性脑电图描记的时空结构，我们分析了6名足月新生儿和7名孕龄小于32周的早产新生儿在0.8至16.8赫兹频段的平均谱功率。最显著的结果表明，在2.8 - 14.8赫兹频段记录的暴发前半段平均谱功率显著高于后半段。这种模式在早产儿中比足月新生儿中更明显。在暴发间期的前半段和后半段之间的比较中未观察到明显差异。此外，就中高频带频谱而言，两组的暴发平均谱功率在右侧枕叶区域均高于左侧枕叶区域。
