To replicate and expand upon past research by evaluating sleep and wake electroencephalographic spectral activity in samples of frequent nightmare (NM) recallers and healthy controls.
Computation of spectral activity for sleep (non-REM and REM) and wake electroencephalogram recordings from 18 frequent NM recallers and 15 control participants.
There was higher "slow-theta" (2-5 Hz) for NM recallers than for controls during wake, non-REM sleep and REM sleep. Differences were clearest for frontal and central derivations and for REM sleep cycles 2-4. There was also higher beta activity during NREM sleep for NM recallers. Findings partially replicate past research by demonstrating higher relative "slow-theta" (3-4Hz) for NM recallers than for controls.
Findings are consistent with a neurocognitive model of nightmares that stipulates cross-state anomalies in emotion processing in NM-prone individuals.
通过评估频繁噩梦(NM)回忆者和健康对照样本中的睡眠和清醒脑电图频谱活动,复制并扩展以往的研究。
计算18名频繁NM回忆者和15名对照参与者的睡眠(非快速眼动和快速眼动)和清醒脑电图记录的频谱活动。
在清醒、非快速眼动睡眠和快速眼动睡眠期间,NM回忆者的“慢θ波”(2-5赫兹)高于对照组。额叶和中央导联以及快速眼动睡眠周期2-4的差异最为明显。NM回忆者在非快速眼动睡眠期间的β活动也更高。研究结果通过证明NM回忆者的相对“慢θ波”(3-4赫兹)高于对照组,部分复制了以往的研究。
研究结果与噩梦的神经认知模型一致,该模型规定易患噩梦的个体在情绪处理方面存在跨状态异常。
