A distinctive pattern called premature temporal theta (PT theta) was studied in 436 infants, ranging in age from 24 to 46 weeks. The pattern is seen in early prematurity, maximizes at 29-31 weeks and then diminishes and disappears near term. Usually the pattern is found independently on both temporal areas, but with a right-sided preference. Patients without PT theta or with a significantly low amount had either neurological or non-neurological (medical) conditions. With age there is a tendency for an increase in frequency and a decrease in amplitude. Five different peaks in the amount of this pattern are seen at approximately every month. Unilateral PT theta tends to be seen in older babies, more often on the right side and with an abnormal EEG. An abnormal EEG is usually associated with a delay in both the appearance and disappearance of this wave form. PT theta is also associated mainly with REM or active sleep. A polynomial rather than an exponential or power function best describes these data with changes of age. PT theta may arise from the inferior temporal gyrus and/or especially the transverse gyrus.
在436名年龄在24至46周的婴儿中研究了一种名为早发性颞叶θ波(PT theta)的独特模式。这种模式在早产早期出现,在29 - 31周时达到最大值,然后在接近足月时减少并消失。通常该模式在双侧颞区独立出现,但右侧更常见。没有PT theta或其数量显著较低的患者患有神经或非神经(医学)疾病。随着年龄增长,频率有增加趋势,振幅有减小趋势。这种模式的数量大约每隔一个月会出现五个不同的峰值。单侧PT theta多见于较大婴儿,更常出现在右侧且脑电图异常。脑电图异常通常与这种波形的出现和消失延迟有关。PT theta也主要与快速眼动(REM)睡眠或活跃睡眠有关。用多项式而非指数或幂函数能最好地描述这些随年龄变化的数据。PT theta可能起源于颞下回和/或特别是颞横回。
