“…In line with the respiratory phase-locking hypothesis , we found that the respiratory cycle indeed phase-locks to the stimulus presentations, yielding a respiratory response that differs significantly from baseline (Figure 2). Dynamic responses of the respiratory system to stimulus presentations have been reported previously (Leskovsek, et al; Porges and Raskin, 1969). Using various respiratory measures, several studies found changes in the respiratory cycle following stimulus presentations.…”

“…In addition, all these studies either used extended blocks of stimuli (Birn, et al, 2009; Chang, et al, 2009; van Buuren, et al, 2009) or slow presentation of trials (e.g. Gomez and Danuser, 2010; Gomez, et al, 2004; Leskovsek, et al; Van Diest, et al, 2001). Here – using analysis methods derived from electrophysiological studies – we show for the first time that significant respiratory phase-locking occurs also for affectively neutral conditions.…”

“…First, in view of previous studies suggesting attentional orienting effects on respiration (Boiten, et al, 1994; Leskovsek, et al), we predicted that the respiratory cycle would phase-lock to the stimulus presentations ( respiratory phase-locking hypothesis ). Second, given the strong link between attention and successful encoding (Chun and Turk-Browne, 2007), we expected that this phase-locking effect would be stronger for R-than F-items.…”

The posterior midline region (PMR) –considered a core of the default mode network- is deactivated during successful performance in different cognitive tasks. The extent of PMR-deactivations is correlated with task-demands and associated with successful performance in various cognitive domains. In the domain of episodic memory, functional MRI (fMRI) studies found that PMR-deactivations reliably predict learning (successful encoding). Yet, it is unclear what explains this relation. One intriguing possibility is that PMR-deactivations are partially-mediated by respiratory artifacts. There is evidence that the fMRI signal in PMR is particularly prone to respiratory artifacts, because of its large surrounding blood vessels. Since respiratory fluctuations has been shown to track changes in attention, it is critical for the general interpretation of fMRI results to clarify the relation between respiratory fluctuations, cognitive performance, and fMRI signal. Here, we investigated this issue by measuring respiration during word encoding, together with a breath-holding condition during fMRI-scanning. Stimulus-locked respiratory analyses showed that respiratory fluctuations predicted successful encoding via a respiratory phase-locking mechanism. At the same time, the fMRI analyses showed that PMR-deactivations associated with learning were reduced during breath-holding and correlated with individual differences in the respiratory phase-locking effect during normal breathing. A left frontal region –used as a control region– did not show these effects. These findings indicate that respiration is a critical factor in explaining the link between PMR-deactivation and successful cognitive performance. Further research is necessary to demonstrate whether our findings are restricted to episodic memory encoding, or also extend to other cognitive domains.

An important challenge in respiration related studies is to investigate the influence of external stimuli on human respiration. Auditory stimulus is an important type of stimuli that influences human respiration. However, no one discovered any trend, which relates the characteristics of the auditory stimuli to the characteristics of the respiratory signal. In this paper, we investigate the correlation between auditory stimuli and respiratory signal from fractal point of view. We found out that the fractal structure of respiratory signal is correlated with the fractal structure of the applied music. Based on the obtained results, the music with greater fractal dimension will result in respiratory signal with smaller fractal dimension. In order to verify this result, we benefit from approximate entropy. The results show the respiratory signal will have smaller approximate entropy by choosing the music with smaller approximate entropy. The method of analysis could be further investigated to analyze the variations of different physiological time series due to the various types of stimuli when the complexity is the main concern.
