Abstract
Fluctuations in the heart's activity can modulate the access of external stimuli to consciousness. The link between perceptual awareness and cardiac signals has been investigated mainly in the visual and auditory domain. Here, we investigated whether the phase of the cardiac cycle and the prestimulus heart rate influence conscious somatosensory perception. We also tested how conscious detection of somatosensory stimuli affects the heart rate. Electrocardiograms (ECG) of 33 healthy volunteers were recorded while applying near-threshold electrical pulses at a fixed intensity to the left index finger. Conscious detection was not uniformly distributed across the cardiac cycle but significantly higher in diastole than in systole. We found no evidence that the heart rate before a stimulus influenced its detection, but hits (correctly detected somatosensory stimuli) led to a more pronounced cardiac deceleration than misses. Our findings demonstrate interactions between cardiac activity and conscious somatosensory perception, which highlights the importance of internal bodily states for sensory processing beyond the auditory and visual domain.

Sympathetic nerve and cardiovascular responses to auditory startle and prepulse inhibition. Int J Psychophysiol 2008; 71:149-55.

Abstract
While sudden (startling) sensory stimuli are generally thought of as inducing sympathetic excitation, in humans there is a short-lasting inhibition of limb muscle sympathetic nerve activity (MSNA). This study is the first to examine and contrast the effects of acoustic startle and the prepulse inhibition of startle (PPI) on MSNA, blood pressure, heart rate, and eye blinks. Startle elicited a two-component withdrawal of MSNA: an early inhibition of one sympathetic burst followed by a second inhibition. PPI abolished the early, but not the late MSNA inhibition. Prepulse stimuli alone had no early inhibitory effects on MSNA. Early MSNA inhibition, which may occur at latencies of approximately 100 ms, appears to be part of a CNS-generated startle reflex which subserves automatic defensive responses to potential threats. The late MSNA inhibition coincided with the stimulus-induced blood pressure increase and is probably an inhibitory reflex response.

Abstract
This study was an extension of the Berntson, Cacioppo, and Fieldstone (1996) study that found that attending to visual illusions presented with text (usually a question directing attention to the illusory property) lengthened heart period via uncoupled vagal activation. Eighty participants were assigned to one of four groups that received either the original Berntson et al. illusions or a modification formed by the factorial combination of whether the illusion and its related text were present or absent. Participants also performed the same serial-subtraction mental-arithmetic task from Berntson et al. During the mental-arithmetic task heart period (HP) shortened, respiratory sinus arrhythmia (RSA) was reduced, and preejection period (PEP) shortened, which indicated a reciprocally coupled sympathetic activation and parasympathetic inhibition mode of cardiac control. Although idiographic analyses found this to be the most common control mode, all other modes were also obtained – especially the nonreciprocal modes of coactivation and coinhibition. During the visual task, PEP lengthened for all groups indicating uncoupled sympathetic inhibition while attending to the stimuli; however, HP differed depending upon the illusion factor. HP lengthened when illusions were absent, but unlike Berntson et al. it shortened when illusions were present. Idiographic analyses found that although most participants showed sympathetic inhibition, approximately equal numbers of participants showed parasympathetic activation and inhibition. Variation in response stereotypy may mask cardiac responses elicited by subtle cognitive phenomena such as the processing of visual illusions, especially in passive viewing tasks. We also suggest that individual differences in mental effort needed to integrate top-down and bottom-up perceptual processes, or personality variables such as the need for cognition, may contribute to response variability in the visual task.

Abstract
Lacey and Lacey (1974) suggested that during reaction time tasks higher brain centers dynamically adjust efferent vagal nerve pulses to the sino-atrial node of the heart, inducing phase-dependent heart rate changes. Since then, animal and human neuro-physiological results have provided evidence for this hypothesis. Higher subcortical and cortical brain centers may have reciprocal interactive pathways relating to autonomic control comparable to those at the level of peripheral autonomic changes and brain stem reflexes. In humans such central effects may be observed in the short latency vagal control of heart rate that has been studied mostly in reaction time (RT) tasks. RT task parameters modulate vagal pulses to the cardiac sino-atrial node (SAN), which in turn exerts a phase-dependent change in the ongoing cardiac interbeat interval. Simulations of human RT task effects in an animal model of heart rate change support this hypothesis. The current study examined evidence for vagal control of three human phasic heart rate responses in RT tasks. The evidence indicates that the initiation of an RT response triggers a reflexive shift from vagal activation to vagal inhibition. This shift is cardiac cycle phase dependent. Graded anticipatory cardiac deceleration during the warning interval of an RT task varies with task relevance and time uncertainty. This response may be part of a control process engaged in time keeping. Hence, temporal variables mediate the central-autonomic-vagal modulation of heart rate.

Abstract
Electronic fetal monitoring technology is capable of monitoring and recording maternal heart rate (MHR) patterns that mimic fetal heart rate (FHR) patterns. The ability to distinguish one from the other requires knowledge of FHR and MHR characteristics and monitoring technology. Application of this knowledge may prevent fetal injury and death. This article reviews heart rate monitoring technology and the similarities and differences between MHR and FHR baselines, accelerations, and decelerations. Three case reports are described in which the MHR was mistaken for the FHR prior to the diagnosis of fetal demise. Guidelines to confirm fetal life and prevent misidentification are proposed.

Abstract
Abstract The acoustic startle reflex (ASR) is modulated by a number of experimental factors, the most important of which in the field of psychopathology is weak prestimulation: The ASR is reliably reduced if preceded briefly by a weaker stimulus (i. e., the prepulse), an effect known as prepulse inhibition (PPI). PPI is thought to reflect centrally-mediated sensorimotor gating of stimuli, preventing cognitive overload and behavioural confusion. PPI is impaired in a variety of psychiatric disorders, notably schizophrenia, as well as in individuals who score high on psychometric measures of psychosis proneness. Two experiments examined the association of personality (trait emotionality) and PPI at three prepulse-to-pulse intervals (30, 60 and 120 ms). Consistent with previous reports, findings from both experiments showed highly significant PPI (defined as percentage reduction in the amplitude of the ASR), which increased with prepulse-to-pulse interval (30 < 60 < 120 ms). A novel finding was that, in both experiments 1 (N = 36) and 2 (N = 63), the trait of neuroticism was negatively correlated with PPI; in addition, a measure of positive incentive motivation (i. e., Behavioural Activation System, Drive subscale; BAS-Drive) was also negatively correlated with PPI. These trait emotionality associations were independent of gender. Possible causal explanations of these personality associations are outlined. It is concluded that, in order to clarify the aetiological role of sensorimotor gating in psychopathological conditions (e. g., schizophrenia, often entailing emotional activation), trait emotionality variance should be routinely examined in future PPI studies.

Abstract
OBJECTIVE To investigate the psychological (affective and symptomatic) and physiological (autonomic and cortisol) responses to postprandial mental stress in women with irritable bowel syndrome (IBS). It was hypothesized that patients with IBS would show exaggerated autonomic and cortisol responses to the psychological stressor and that the stressor would enhance gastrointestinal symptoms. METHOD Twenty-four women with IBS and 20 healthy women participated in the two-day study protocol. Both days were identical, with the exception that on one day, a stressful mental task was completed after ingestion of a standard meal. Heart rate variability, cortisol, affective, and symptomatic responses were measured before and after application of the stressor. RESULTS Patients with IBS demonstrated increased negative affect at baseline and in response to the stressor. Gastrointestinal symptoms were not affected by the stressor. Appraisal of the stressor by patients with IBS was not different from that of controls. There were no group differences in the autonomic response to the stressor. There was no overall cortisol response to the stressor in either group. CONCLUSIONS Patients with IBS respond with greater negative affect to postprandial psychological stress as well as to food intake alone, and they can be distinguished from controls on the basis of self-report data. Patients with IBS cannot be differentiated from controls on the basis of the pattern of changes in sympathetic activation after the mental stressor. The stressor used in this study did not elicit a cortisol response in either group.

Abstract
A widely held hypothesis within behavioral medicine is that cardiovascular reactivity is a risk factor for cardiovascular disease. The measurement model for this cardiovascular reactivity is rather simple. A basal level of function is seen to increase while the organism is stressed and then return to basal function. We argue that this model is incomplete and that other forms of 'reactivity' may be relevant to pathophysiology. A pathophysiological hypothesis is discussed which assumes a cyclic heart beat generation mechanism that is sensitive to stimulation only at certain phases of its cycle. Implications of this hypothesis for measurement are developed to illustrate the point that models of normal function can determine the measures most relevant to pathophysiology.

Abstract
Between- and within-channel auditory selective attention were examined by presenting subjects with tone pips randomly to opposite ears; some pips had a slightly different pitch. Subjects were instructed to count rare, deviant tone pips at one ear and ignore all input to the other ear. Heart rate was sampled twice: once for the attended tone pips and once for the nonattended stimulus series. Heart rate responded differently to attended tone pips. While subjects were waiting for the rare stimulus to occur, heart rate slowed until the deviant stimulus was detected, which was followed by heart rate acceleration. Anticipatory heart rate deceleration was largely absent for nonattended series, and rare tone pips presented at the nonattended ear were not followed by acceleratory recovery. All tone pips elicited cardiac cycle time effects, that is, stimuli presented at short delays after the R wave prolonged the concurrent interbeat interval more than stimuli presented later. The cardiac cycle time effect was not altered by stimulus relevance (attended vs. nonattended) or significance (standard vs. rare). These results suggest that all stimuli receive preliminary perceptual analysis, but only attended stimuli are processed for further evaluation.

Abstract
We asked whether the heart rate response to respiratory change varied as a function of timing within the cardiac cycle. Respiratory and electrocardiographic data were collected from seven men and seven women during three weekly sessions under conditions of normal and visually paced breathing. Results revealed that, when inspiration began sooner than 500 ms before the subsequent heart beat, inspiration had little effect on the subsequent interbeat interval. However, the timing of the subsequent beat was accelerated when inspiration began later than 450 ms before this heart beat. Similar relationships were observed for expiratory onset. Results were not attributable to volitional control or rate of breathing. The modulation of respiratory sinus arrhythmia by the timing of respiratory events in the cardiac cycle has implications for the role of vagal control in the synchronization of heart rate with respiratory and behavioral actions.

Abstract
This study examined age changes in three aspects of heart rate responsivity elicited in an auditory oddball task; anticipatory heart rate change, primary bradycardia, and respiratory sinus arrhythmia. Three age groups (5-, 7-, and 9-year-old boys) were presented with series of target (15%) and standard (85%) tones. The results were consistent with the findings reported previously in the adult literature. Heart rate decreased in anticipation of the target tone. The morphology of anticipatory deceleration was somewhat different for the 5-year-olds compared to the older children. Stimuli presented during the early part of the cardiac cycle induced added deceleration, but this primary bradycardia did not differ between age groups. Respiratory sinus arrhythmia did not discriminate between age groups but was suppressed during the performance of the oddball task relative to base level. It was concluded that these three aspects of heart rate responsivity show developmental constancy rather than change.

Abstract
Cardiac cycle time effects refer to the relative lengthening or shortening of a single cardiac cycle as a function of when in the cycle brief sensorimotor events occur. These effects may provide short-latency measures of cardiac sensitivity to psychological events. Conventional representations have, however, failed to clearly separate changes in interbeat interval due to cycle time--i.e., phase dependent changes--from other types of change. This paper advocates a particular technique of plotting to solve these representation problems. Heartbeat timing is represented in real time and in the context of beats both preceding and following the event of interest. The plot, a phase-sensitive plot, conceptualizes phase-sensitive (cardiac cycle time) effects as a change in linear or higher order trend. Thus, an adaptation of trend analysis is proposed as an efficient statistical analysis that follows directly from the proposed representational technique.
