“…EMG responses on these trials were not further analyzed. Each experimental session consisted of 60 startle probes with a jittering inter-stimulus-interval of 8 to 12 s. Earlier study protocols were extended (Schulz et al, 2009a;Schulz et al, 2009b;Schulz et al, 2009c), in that startle stimuli were presented with six different latencies after a detected R-wave (0 ms, 100 ms, 200 ms, 300 ms, 400 ms, and 500 ms). The first experimental startle session ('preintervention') was followed by a five-minute assessment of cardiovascular beat-to-beat and blood pressure data prior to the intervention, which was a three-minute experimental intervention (CP vs. control) with continuing measurement of cardiovascular data, followed by the post-interventional startle session ('post-intervention'), and again a five-minute cardiovascular data assessment.…”

“…In this CMS paradigm, increased baro-afferent feedback during the early cardiac cycle phase attenuates startle responsiveness compared to the late cardiac cycle phase (Richter et al, 2009;Schulz et al, 2009a;Schulz et al, 2009b;Schulz et al, 2009c). The current study was designed to clarify whether altered baro-afferent neural traffic induced by acute autonomic stress may affect the CMS.…”

“…An alternative to interoceptive tasks, which confound visceral sensations and their perception, is provided by the cardiac modulation of startle (CMS) [8][9][10][11][12][13]. CMS assesses afferent neural traffic originating from the cardiovascular system independent of the conscious perception of visceral sensations [9].…”

One contribution of 16 to a theme issue 'Interoception beyond homeostasis: affect, cognition and mental health'. Current approaches to assess interoception of respiratory functions cannot differentiate between the physiological basis of interoception, i.e. visceralafferent signal processing, and the psychological process of attention focusing. Furthermore, they typically involve invasive procedures, e.g. induction of respiratory occlusions or the inhalation of CO 2 -enriched air. The aim of this study was to test the capacity of startle methodology to reflect respiratoryrelated afferent signal processing, independent of invasive procedures. Forty-two healthy participants were tested in a spontaneous breathing and in a 0.25 Hz paced breathing condition. Acoustic startle noises of 105 dB(A) intensity (50 ms white noise) were presented with identical trial frequency at peak and on-going inspiration and expiration, based on a new pattern detection method, involving the online processing of the respiratory belt signal. The results show the highest startle magnitudes during on-going expiration compared with any other measurement points during the respiratory cycle, independent of whether breathing was spontaneous or paced. Afferent signals from slow adapting phasic pulmonary stretch receptors may be responsible for this effect. This study is the first to demonstrate startle modulation by respiration. These results offer the potential to apply startle methodology in the non-invasive testing of interoception-related aspects in respiratory psychophysiology.This article is part of the themed issue 'Interoception beyond homeostasis: affect, cognition and mental health'.

“…Blink rate is linked to health [29], eye sensitivity [30] and reaction to alerts [31]. Doughty [32] defines spontaneous eyeblink rate (SEBR) as a common standard, though indicates that large variance of SEBR values are reported between medical studies.…”
