“…Many organs interact with brain rhythms. For example, the cardiovascular, gastrointestinal and respiratory systems are known to show ultradian rhythmicity, which in turn interacts with brain rhythms [29][30][31] . These 'body oscillators' potentially constrain endogenous neuronal dynamics (e.g., 30,32,33 ) and might act as common 'clocks', organizing neuronal activity across brain regions.…”

The beneficial effect of sleep on memory consolidation relies on the precise interplay of slow oscillations (SOs) and spindles. However, whether these rhythms are orchestrated by an underlying pacemaker has remained elusive. Here, we tested whether respiration, which has been shown to impact brain rhythms and cognition during wake, shapes memory reactivation by modulating sleep-related oscillations and their interplay in humans. We recorded scalp EEG and respiration throughout an experiment in which participants acquired associative memories before taking a nap. Our results reveal that respiration strongly modulates the emergence of sleep oscillations. Specifically, SOs, spindles as well as their interplay (i.e., coupled SO_spindle complexes) systematically increase towards inhalation peaks. Moreover, the strength of respiration-SO_spindle coupling is linked to the extent of memory reactivation during SO_spindles. Our results identify respiration as a potential pacemaker for memory consolidation in humans and highlight the critical role of brain-body interactions during sleep.

The beneficial effect of sleep on memory consolidation relies on the precise interplay of slow oscillations and spindles. However, whether these rhythms are orchestrated by an underlying pacemaker has remained elusive. Here, we tested the relationship between respiration, which has been shown to impact brain rhythms and cognition during wake, sleep-related oscillations and memory reactivation in humans. We re-analysed an existing dataset, where scalp electroencephalography and respiration were recorded throughout an experiment in which participants (N = 20) acquired associative memories before taking a nap. Our results reveal that respiration modulates the emergence of sleep oscillations. Specifically, slow oscillations, spindles as well as their interplay (i.e., slow-oscillation_spindle complexes) systematically increase towards inhalation peaks. Moreover, the strength of respiration - slow-oscillation_spindle coupling is linked to the extent of memory reactivation (i.e., classifier evidence in favour of the previously learned stimulus category) during slow-oscillation_spindles. Our results identify a clear association between respiration and memory consolidation in humans and highlight the role of brain-body interactions during sleep.

“…This theoretical framework focuses on interindividual variability in rhythms from the brain and the body and its relation with behavior (Criscuolo et al, 2022). Hence, to move forward in a holistic understanding of physiological functioning, the concurrent assessment of rhythmic body-brain signals becomes necessary (Azzalini et al, 2019;Criscuolo et al, 2022;Draguhn & Sauer, 2023;Varga & Heck, 2017).…”

This scoping review systematically investigates the application of embodied hyperscanning methodologies in neuroscience research. Hyperscanning enables the simultaneous recording of physiological signals from multiple participants. We highlight the trend towards integrating Mobile Brain/Body Imaging (MoBI) within the 4E research framework, which emphasizes the interconnectedness of brain, body, and environment in cognitive processes. Our analysis reveals a geographic concentration of hyperscanning studies in the Global North, indicating a disparity in neuroscience research distribution. This calls for global collaboration and transcultural research to balance the field. The predominant use of Electroencephalogram (EEG) in these studies suggests a traditional brain-centric perspective in social neuroscience. Future research directions should focus on integrating diverse techniques to capture the dynamic interplay between brain and body functions in real-world contexts. Our review also finds a preference for tasks involving real social interactions, aligning with the aims of social neuroscience to comprehend social behavior in natural settings. Nevertheless, the analysis in hyperscanning studies is often limited to physiological signal synchrony between participants. This suggests a need for more holistic and complex approaches that combine inter-corporeal synchrony with intra-individual measures.In conclusion, embodied hyperscanning represents a cutting-edge methodology, pushing the boundaries of our understanding of the complex interactions between the brain, body, the environment, and social behavior. Overcoming geographic and methodological constraints will enable a more nuanced and inclusive comprehension of cognitive processes. The future of the neuroscience of relationships lies in embracing the complexity of cognition, integrating diverse methods and theories to enrich our grasp of human social behavior in its natural context.
