“…Note that daily routine activities such as typing, washing dishes, or buying food at the supermarket are generally not frequent in dream reports (Schredl 2010). Motivational and emotional content is more prominent in REM than in NREM dreaming (Smith et al 2004). This is consistent with the finding that several limbic and mesolimbic dopaminergic regions are Fig.…”

“…1). On the one hand, the amygdala, along with the brainstem, is involved in the cardiovascular regulation during sleep (Desseilles et al 2006), and may thus reflect autonomic regulation in response to intense emotions, in particular fear and anxiety that are often experienced in dreams Smith et al 2004). On the other hand, amygdala connections with the hippocampus, thalamus, medial PFC, and ACC have an important role in assigning affective values to stimuli and thus potentially strengthening stimulus-outcome associations (see Sect.…”

In this chapter, we review studies investigating the role of sleep in emotional functions. In particular, evidence has recently accumulated to show that brain regions involved in the processing of emotional and reward-related information are activated during sleep. We suggest that such activation of emotional and reward systems during sleep underlies the reprocessing and consolidation of memories with a high affective and motivational relevance for the organism. We also propose that these mechanisms occurring during sleep promote adapted cognitive and emotional responses in the waking state, including overnight performance improvement, creativity, and sexual functions. Activation across emotional-limbic circuits during sleep also appears to promote emotional maturation and the emergence of consciousness in the developing brain.

“…During REM sleep, heightened activation of forebrain structures essential to motivation and emotion-lateral hypothalamic areas, infralimbic, prelimbic, and limbic areas (amygdaloid complex) -imposes vivid recall (Braun et al, 1997;Solms, 2000). Furthermore, motivational states with active limbic processes in REM sleep are rendered compatible with visual-spatial images in occipital and parietal cortices (Smith et al, 2004). Thus, cortical activation is biased toward REM dreaming.…”

a b s t r a c tDreaming pertains to both REM and NREM sleep. However, frequency and regional specific differences in EEG activity remains controversial. We investigated NREM and REM sleep EEG power density associated with and without dream recall in 17 young subjects during a 40-h multiple nap protocol under constant routine conditions. NREM sleep was associated with lower EEG power density for dream recall in the delta range, particularly in frontal derivations, and in the spindle range in centro-parietal derivations. REM sleep was associated with low frontal alpha activity and with high alpha and beta activity in occipital derivations. Our data indicate that specific EEG frequency-and topography changes underlie differences between dream recall and no recall after both NREM and REM sleep awakening. This dual NREM-REM sleep modulation holds strong implications for the mechanistic understanding of this complex ongoing cognitive process.

Amygdala connections with HC, thalamus, the septal nuclei, mPFC and ACC may also have an important role in strengthening affective value associated to memories (Sterpenich et al, 2007, 2009).…”

“…While mental activity during REM and NREM sleep vary across the night sleep, with NREM dreams becoming longer, less thought-like and more dream-like and bizarre, thus resembling REM dreams in the morning (Fosse et al, 2004; Wamsley et al, 2007a), dream content analyses report generally higher emotional intensity in REM than in NREM dreams (Smith et al, 2004; McNamara et al, 2005; Wamsley et al, 2007a), consistent with the robust activation of limbic structures during REM sleep. On the other hand, dreamer-initiated friendliness is frequent in NREM dreams, while aggressive social interactions may be more characteristic of REM reports (McNamara et al, 2005).…”

Recent studies in sleep and dreaming have described an activation of emotional and reward systems, as well as the processing of internal information during these states. Specifically, increased activity in the amygdala and across mesolimbic dopaminergic regions during REM sleep is likely to promote the consolidation of memory traces with high emotional/motivational value. Moreover, coordinated hippocampal-striatal replay during NREM sleep may contribute to the selective strengthening of memories for important events. In this review, we suggest that, via the activation of emotional/motivational circuits, sleep and dreaming may offer a neurobehavioral substrate for the offline reprocessing of emotions, associative learning, and exploratory behaviors, resulting in improved memory organization, waking emotion regulation, social skills, and creativity. Dysregulation of such motivational/emotional processes due to sleep disturbances (e.g., insomnia, sleep deprivation) would predispose to reward-related disorders, such as mood disorders, increased risk-taking and compulsive behaviors, and may have major health implications, especially in vulnerable populations.
