(a) Functional neuroanatomy of REM sleep. Brain regions more activated during REM sleep are shown in red and less activated in blue. Abbreviations: dlPFC: dorsolateral prefrontal cortex; mPFC: medial prefrontal cortex; REM: rapid eye movement sleep; VTA: ventral tegmental area. (b) The specific pattern of cerebral activation/deactivation may explain and be correlated with specific phenomenological characteristics of dreams pertaining to memory, reward and emotional processing, attentional control, visual imagery, delusional beliefs, and mentalizing.

Recent neuroimaging, neuroanatomical, neurophysiological, pharmacological, and dream content analysis studies have shed new light on the neural underpinnings of dreaming. In this article, we review converging evidence from these distinct lines of research suggesting that the generation of dreams primarily relies on the activation of brain networks...

Context 1
... the other hand, regions activated during REM sleep in humans are consistent with some main characteristics of the dreaming experience, usually associated with this sleep stage (Figure 1). A first set of activated regions consists in the thal- amus, basal forebrain, as well as in limbic and paralimbic structures, including bilateral amygdala, hippocampus, mPFC, and ACC ( Braun et al., 1997;Maquet et al., 1996;Nofzinger et al., 1997). ...
Context 2
... activity in these regions may explain the disorienta- tion, lack of insight, illogical thinking, and poor working memory found in REM dreaming. Figure 1 shows the main anatomical regions whose activity is modified during REM sleep and their plausible contribution to distinctive features in REM dreams. ...
