“…For example, task‐irrelevant visual information can be more inhibited during systole than diastole (Pramme et al., 2014, 2016). Emotional facial expressions were detected better (Azevedo et al., 2018; Garfinkel et al., 2014; Mizuhara & Nittono, 2023) and perceived more intensely (Garfinkel et al., 2014; Leganes‐Fonteneau et al., 2021) at systole than diastole. Feedback information processing associated with monetary gain and loss was also greater at systole than diastole (Kimura, 2019).…”

“…The recording settings were identical to those used in our previous study (Mizuhara & Nittono, 2023), except that the reference electrode was placed at the nose tip. Biosignals were recorded using an ActiveTwo system (BioSemi, Amsterdam, Netherlands) with a bandpass filter of 0-400 Hz and a sampling rate of 2048 Hz.…”

“…Cardiac field artifacts can be removed from the electroencephalogram (EEG) relatively easily by independent component analysis (ICA) because they occur simultaneously with electrocardiogram (ECG) signals. However, heartbeat‐evoked cortical potentials (HEPs) affect not only the period after stimulus onset but also the baseline period differently for stimuli presented at systolic and diastolic phases and cannot be distinguished clearly from ERP responses to sensory stimuli (Kimura, 2019; Mizuhara & Nittono, 2023). The subtraction method is useful to circumvent this issue.…”

The systolic and diastolic phases of the cardiac cycle are known to affect perception and cognition differently. Higher order processing tends to be facilitated at systole, whereas sensory processing of external stimuli tends to be impaired at systole compared to diastole. The current study aims to examine whether the cardiac cycle affects auditory deviance detection, as reflected in the mismatch negativity (MMN) of the event‐related brain potential (ERP). We recorded the intensity deviance response to deviant tones (70 dB) presented among standard tones (60 or 80 dB, depending on blocks) and calculated the MMN by subtracting standard ERP waveforms from deviant ERP waveforms. We also assessed intensity‐dependent N1 and P2 amplitude changes by subtracting ERPs elicited by soft standard tones (60 dB) from ERPs elicited by loud standard tones (80 dB). These subtraction methods were used to eliminate phase‐locked cardiac‐related electric artifacts that overlap auditory ERPs. The endogenous MMN was expected to be larger at systole, reflecting the facilitation of memory‐based auditory deviance detection, whereas the exogenous N1 and P2 would be smaller at systole, reflecting impaired exteroceptive sensory processing. However, after the elimination of cardiac‐related artifacts, there were no significant differences between systole and diastole in any ERP components. The intensity‐dependent N1 and P2 amplitude changes were not obvious in either cardiac phase, probably because of the short interstimulus intervals. The lack of a cardiac phase effect on MMN amplitude suggests that preattentive auditory processing may not be affected by bodily signals from the heart.

“…Similarly, investigations into the effect of breathing on perception and emotion have yielded inconsistent findings. For example, some studies have reported effects of breathing phase on emotion processing and perception (Kluger et al., 2021; Mizuhara & Nittono, 2023; Zelano et al., 2016), while others have not (Johannknecht & Kayser, 2022; Mizuhara & Nittono, 2022). One reason for these mixed results may be the utilization of diverse technical and statistical methodologies for identifying variations in behavioral performance throughout the respiratory cycle.…”

Recent studies have indicated that breathing shapes the underlying oscillatory brain activity critical for episodic memory, potentially impacting memory performance. However, the literature has presented conflicting results, with some studies suggesting that nasal inhalation enhances visual memory performance, while others have failed to observe any significant effects. Furthermore, the specific influence of breathing route (nasal vs. mouth) and the precise phase of the respiratory cycle during which stimuli are presented have remained elusive. To address this, we employed a visual recognition memory (VRM) and electroencephalography paradigm in which stimuli presentation was phase‐locked to either inhalation or exhalation onset, using a within‐subject design where participants performed the memory task while engaging in separate sessions of nose and mouth breathing. We show that neither breathing route nor breathing phase has a significant impact on VRM performance as measured by d‐prime, with the data supporting the null hypothesis. However, we did find an effect of breathing phase on response bias, with participants adopting a more conservative decision criterion during exhalation. Moreover, we found that breathing phase during memory encoding shaped the late parietal effect (LPE) amplitude, while the Frontal Negative Component (FN400) and LPE during recognition were less impacted. While our study demonstrates that breathing does not shape VRM performance, it shows that it influences brain activity, reinforcing the importance of further research to elucidate the extent of respiratory influence on perception, cognition, and behavior.

“…Other studies have found that inspiration increases the speed of emotional processing (Zelano et al, 2016), and that participants make more volitional movements during expiration (Park et al, 2020). These and many more recent reports suggest that respiratory rhythms play a fundamental role in shaping exteroceptive, affective (Bagur et al, 2021;Mizuhara & Nittono, 2023;Zelano et al, 2016), and cognitive behaviour (for reviews, see Allen et al, 2022;Azzalini et al, 2019;Braendholt et al, 2023;Heck et al, 2022).…”

Respiratory rhythms play a critical role not only in homeostatic survival, but also in modulating other non-interoceptive perceptual and affective processes. Recent evidence from both human and rodent models indicates that neural and behavioural oscillations are influenced by respiratory state as breathing cycles from inspiration to expiration. To explore the mechanisms behind these effects, we carried out a psychophysical experiment where 41 participants categorised dot motion and facial emotion stimuli in a standardised discrimination task. When comparing behaviour across respiratory states, we found that inspiration accelerated responses in both domains. We applied a hierarchical evidence accumulation model to determine which aspects of the latent decision process best explained this acceleration. Computational modelling showed that inspiration reduced evidential decision boundaries, such that participants prioritised speed over accuracy in the motion task. In contrast, inspiration shifted the starting point of affective evidence accumulation, inducing a bias towards categorising facial expressions as more positive. These findings provide a novel computational account of how respiratory rhythms modulate distinct aspects of perceptual and affective decision-dynamics.
