2017, Sleep Medicine ReviewsCitation Excerpt :This dissociation is suggestive of a high-order visual processing during sleep, without external visual input and with a decreased activity of V1. The majority of subsequent neuroimaging studies (for reviews [109,110]) have shown substantial differences in brain activity during REM compared with NREM sleep, in which activation diminishes from waking levels [107,111]. In particular, REM sleep is characterized by an increased activity in the pons and midbrain, thalamus, basal ganglia, hypothalamus, ventral striatum and visual association cortices, and midline limbic and paralimbic areas, as well as in orbitofrontal and paracingulate cortices and in part of the mPFC [105,107], whereas the dlPFC remains deactivated after the transition from NREM to REM sleep [105,107,108,112].
Daydreams and nap dreams: Content comparisons
2015, Consciousness and CognitionCitation Excerpt :However, the mind-wandering theory is not yet comprehensive enough to adequately explain the ensemble of our findings including: (1) why NREM nap dreams showed lower levels of sensory experience and emotion than did daydreams; (2) why REM nap dreams exceeded NREM nap dreams so markedly on all attributes; (3) why REM nap dreams and daydreams failed to differ on the positive and negative emotion measures when some research suggests that dreams contain more negative emotions than waking event reports (Nielsen, Deslauriers, & Baylor, 1991) while mind-wandering contains more positive emotions (Fox et al., 2013; Schredl, 2010). Also, the fact that the default mode network is only partially activated during REM sleep (Pace-Schott, 2010) places these mind-wandering theories on a questionable neurophysiological footing. In sum, while the mind-wandering hypothesis is a novel and promising attempt to unify different forms of imagery generation, it lacks both the phenomenological and neurophysiological detail to explain all findings from the present contrasts between REM nap, NREM nap and daydream imagery.
