本研究探讨了快速眼动（REM）睡眠期间海马θ波和脑桥波（P波）的动态变化与快速眼动（REM）密度之间的相关性。估计Theta波峰值频率和theta振幅作为每个3s段的theta波动力学参数。峰值频率和θ振幅与P波和REM密度呈正相关，但它们的详细相关性彼此不同。P波/REMs密度与P波/REMs密度的相关性无显著性差异。另一方面，θ振幅对P波/REM密度的依赖性随着REM/P波密度的增加而显著增加。由于海马theta波和P波参与REM睡眠期的学习记忆功能，因此theta参数与P波密度之间的相关性可能有助于阐明这些功能。(C)2004年Elsevier爱尔兰有限公司和日本神经科学学会。All rights reserved.
The present study examined the correlations between the dynamics of hippocampal theta waves and pontine waves (P waves) and rapid eye movements (REMs) densities during REM sleep. Theta wave peak frequency and theta amplitude were estimated as the parameters of theta wave dynamics in each 3 s segment. The peak frequency and theta amplitude were positively correlated with P wave and REMs densities, however their detailed correlation properties were distinct from each other. Dependency of peak frequency on P wave/REMs density did not change significantly from that on REMs/P wave density. On the other hand, dependency of the theta amplitude on P wave/REMs density significantly increased with an increased REMs/P wave density. Because hippocampal theta waves and P waves are involved in learning and memory functions during REM sleep, the correlation between theta parameters and P wave density might help to clarify these functions.
