Dream is a state of consciousness characterized by internally-generated sensory, cognitive and emotional experiences occurring during sleep. Dream reports tend to be particularly abundant, with complex, emotional, and perceptually vivid experiences after awakenings from rapid eye movement (REM) sleep. This is why our current knowledge of the cerebral correlates of dreaming, mainly derives from studies of REM sleep. Neuroimaging results show that REM sleep is characterized by a specific pattern of regional brain activity. We demonstrate that this heterogeneous distribution of brain activity during sleep explains many typical features in dreams. Reciprocally, specific dream characteristics suggest the activation of selective brain regions during sleep. Such an integration of neuroimaging data of human sleep, mental imagery, and the content of dreams is critical for current models of dreaming; it also provides neurobiological support for an implication of sleep and dreaming in some important functions such as emotional regulation.
梦是一种意识状态，其特征是在睡眠期间出现内部产生的感觉、认知和情感体验。梦的报告往往特别丰富，在快速眼动 (REM) 睡眠后醒来时会有复杂、情绪化和感知生动的体验。这就是为什么我们目前对做梦的大脑相关性的认识主要来自 REM 睡眠的研究。神经影像学结果表明，REM 睡眠的特征是区域大脑活动的特定模式。我们证明，睡眠期间大脑活动的这种异质性分布解释了许多梦境的典型特征。反过来，特定的梦境特征表明睡眠期间选择性大脑区域的激活。这种对人类睡眠、心理意象和梦境内容的神经影像学数据的整合对于当前的做梦模型至关重要；它也为睡眠和做梦在一些重要功能中的作用提供了神经生物学支持，如情绪调节。
