情绪记忆巩固与快速眼动（REM）睡眠有关，最近的证据表明，θ波（4-8赫兹）频率范围内脑电图频谱功率的增加反映了这种活动。快速眼动睡眠与创伤后应激障碍（PTSD）和情绪适应有关。在这项横断面研究中，使用临床医生管理的创伤后应激障碍量表评估了30名创伤暴露的年轻健康非裔美国成年人的创伤后应激障碍状态。连续两次进行夜间多导睡眠图（PSG）记录，并对睡眠阶段的数据进行评分。采用定量脑电图谱分析方法测量第二晚PSG快速眼动睡眠期间的theta频率分量。我们的目的是比较创伤暴露的参与者之间的相对θ波功率，他们要么是有弹性的，要么是患有PTSD的。结果表明，与创伤后应激障碍的参与者相比，有弹性的参与者在快速眼动初期和后期的右前额叶θ波能量更高。快速眼动睡眠期间右脑前额叶θ波功率可作为创伤暴露个体适应性情绪记忆处理能力的生物标志物。
Emotional memory consolidation has been associated with rapid eye movement (REM) sleep, and recent evidence suggests that increased electroencephalogram spectral power in the theta (4–8 Hz) frequency range indexes this activity. REM sleep has been implicated in posttraumatic stress disorder (PTSD) as well as in emotional adaption. In this cross-sectional study, thirty young healthy African American adults with trauma exposure were assessed for PTSD status using the Clinician Administered PTSD Scale. Two consecutive night polysomnographic (PSG) recordings were performed and data scored for sleep stages. Quantitative electroencephalographic spectral analysis was used to measure theta frequency components sampled from REM sleep periods of the second-night PSG recordings. Our objective was to compare relative theta power between trauma-exposed participants who were either resilient or had developed PTSD. Results indicated higher right prefrontal theta power during the first and last REM periods in resilient participants compared with participants with PTSD. Right hemisphere prefrontal theta power during REM sleep may serve as a biomarker of the capacity for adaptive emotional memory processing among trauma-exposed individuals.
