Brainstem sources of cardiac vagal tone and respiratory sinus arrhythmia
KEY POINTS Cardiac vagal tone is a strong predictor of health, although its central origins are unknown. Respiratory-linked fluctuations in cardiac vagal tone give rise to respiratory sinus arryhthmia (RSA), with maximum tone in the post-inspiratory phase of respiration. In the present study, we investigated whether respiratory modulation of cardiac vagal tone is intrinsically linked to post-in...
متن کاملWhither vagal tone.
Measures of respiratory sinus arrhythmia (RSA) have been widely applied in the physiological and psychophysiological literature as an index of vagal control of the heart. Despite an extensive literature, however, differences in interpretation remain within the field. A guiding conception for several contributions in this issue is the notion of separate brainstem centers involved in parasympathe...
متن کاملVagal Tone 1 Running head: VAGAL TONE, TEMPERAMENT, AND EMOTION REGULATION Vagal Tone and Temperament as Predictors of Emotion Regulation Strategies in Young Children
This study examines vagal tone and two dimensions of temperament as predictors of emotion regulation (ER) strategy use among children (n = 54, ages 4-7) of mothers varying in risk for depression. In one protocol, ER strategies were coded by trained raters during a delay of gratification task. Physiological and psychometric data were collected in an independent and separate protocol: vagal tone ...
متن کاملCardiac Vagal Tone, defensiveness, and motivational style.
Cardiac Vagal Tone has been proposed as a stable biological marker for the ability to sustain attention and regulate emotion [Porges, Monographs of the Society for Research in Child Development 59 (1994) 167-186]. Vagal tone is a physiological index of parasympathetic nervous system influence on the heart that has predicted a number of emotional behaviors and styles in infants, children, and ad...
متن کاملIncreased Vagal Tone and Sleep Apnea Syndrome
It has been observed that atrial overdrive pacing abolishes sleep apnea syndrome, but how it does so has not been explained. There is a possibility that it sends a retrograde inhibitory impulse to the vagal center in the brainstem, which in turn reduces the vagal tone, and thus prevents sleep apnea. Therefore, medical vagolytics such as atropine type of drugs should have the same effect. This i...
