In the rat, an ontogenetic study of theta rhythm during paradoxical sleep shows a clear evolution between the 14th and the 30th postnatal day. During this period, its mean frequency increases from 5 to 7 cycles per second, and its spectrum shows significant changes. These parameters (mean frequency and spectral components) of the theta rhythm could be a useful index of brain maturation in the rat.
在大鼠中，对异相睡眠期间θ节律的个体发生学研究表明，在出生后第14天至第30天之间有明显的演变。在此期间，其平均频率从每秒5次增加到7次，并且其频谱显示出显著变化。θ节律的这些参数（平均频率和频谱成分）可能是大鼠大脑成熟的有用指标。
