“…Here, N400 effects are described as weaker, partial and delayed compared to wakefulness (Bastuji et al, 2002;Brualla et al, 1998;Daltrozzo et al, 2012;Davis et al, 2007;Ibáñez et al, 2006;Rohaut et al, 2015;Steppacher et al, 2016;Strauss and Dehaene, 2019). It has been argued that during sleep, there is decreased long-distance connectivity between brain regions (Boly et al, 2012;Massimini et al, 2005;Spoormaker et al, 2012;Tagliazucchi et al, 2013), and that the sleeping brain may still process semantic information, but in a purely feedforward manner (Strauss and Dehaene, 2019). In the vegetative state (no conscious awareness), it has been found that long-distance connectivity between frontal and temporal regions is disrupted (Boly et al, 2011).…”

“…In the late processing window, a different pattern was observed: the auditory frequency map organisation was better explained by the perceptual and physiological models in N2, in comparison to wakefulness and other sleep stages. A possible interpretation for the increased predictive value as well as for the increased similarity magnitude in N2 in the late processing window might be related to delayed processing occurring during the transition from wakefulness to sleep (Atienza et al, 2001; Bastuji and García-Larrea, 1999; Canales-Johnson et al, 2019; Hennevin et al, 2007; Kouider et al, 2014; Noreika et al, 2020; Strauss and Dehaene, 2019; Strauss et al, 2015; Velluti, 1997). However, it has to be noted that our results seem to point towards a prolonged sensory processing (Fig.…”

In a single day we transition from vigilant wakefulness to unconscious sleep and dreaming, undergoing diverse behavioural, physiological and neural changes. While during the awake state, exogenous stimuli and endogenous changes lead to sensory reorganisation, this remapping has not been charted throughout the sleep-wake cycle. We recorded neural activity in response to a range of tones using electroencephalography during a full-night sleep, and examined whether auditory responses become more similar, dissimilar or remain unchanged between wakefulness, non-rapid (NREM) and rapid eye movement (REM) sleep. We found that neural similarities between pairs of auditory evoked potentials differed by conscious state in both early and late auditory processing stages. Furthermore, tone-pairs neural similarities were modulated by conscious state as a function of tone frequency, where some tone-pairs changed similarity between states and others continued unaffected. These findings demonstrate a state-, stimulus- and time-dependent functional reorganization of auditory processing across the sleep-wake cycle.

“…Particularly the unfamiliar voice triggered larger event-related synchronization in a broad frequency range as compared to a familiar voice, which suggests continued saliency during sleep [ 1 ]. The phenomenon that the sleeping brain preserves (at least to some degree) its ability to process sensory information has previously been shown for a range of stimuli including names [ 2 , 3 ], speech [ 4 , 5 ], complex auditory regularities [ 6 ], or arithmetic violations [ 7 ]. However, questions about the nature of the underlying mechanism continue to be a matter of debate.…”

Past research has demonstrated differential responses of the brain during sleep in response especially to variations in paralinguistic properties of auditory stimuli, suggesting they can still be processed “offline”. However, the nature of the underlying mechanisms remains unclear. Here, we therefore used multivariate pattern analyses to directly test the similarities in brain activity among different sleep stages (non-rapid eye movement stages N1-N3, as well as rapid-eye movement sleep REM, and wake). We varied stimulus salience by manipulating subjective (own vs. unfamiliar name) and paralinguistic (familiar vs. unfamiliar voice) salience in 16 healthy sleepers during an 8-h sleep opportunity. Paralinguistic salience (i.e., familiar vs. unfamiliar voice) was reliably decoded from EEG response patterns during both N2 and N3 sleep. Importantly, the classifiers trained on N2 and N3 data generalized to N3 and N2, respectively, suggesting similar processing mode in these states. Moreover, projecting the classifiers’ weights using a forward model revealed similar fronto-central topographical patterns in NREM stages N2 and N3. Finally, we found no generalization from wake to any sleep stage (and vice versa) suggesting that “processing modes” or the overall processing architecture with respect to relevant oscillations and/or networks substantially change from wake to sleep. However, the results point to a single and rather uniform NREM-specific mechanism that is involved in (auditory) salience detection during sleep.
