On the physiology of interruption after unexpectedness
2021, Biological PsychologyCitation Excerpt :Specifically, in Experiment 2, we focused on a reduction of movement and in Experiment 4, we focused on finger temperature and blood pressure. Temperature and blood pressure have received less attention in research on orienting and freezing, but they are relevant to include because a lowered heart rate in combination with lowered temperature and increased blood pressure would be suggestive of an inhibitory but active state (Reyes del Paso, Vila, & García, 1994; Sawada, 2003; see also Carrive, 2000; Hagenaars, Oitzl et al., 2014; Hagenaars, Roelofs et al., 2014; Roelofs, 2017; Vianna & Carrive, 2005). This would fit with the conceptualization of surprise as a state of interruption for effective action.
Sympathetic contributions to habituation and recovery of the cardiac defense response
2020, Biological PsychologyCitation Excerpt :During the first 3 time-intervals of the response (11 s), heart rate and sympathetic cardiac control showed virtually mirror-inverted time course patterns: while heart rate exhibited a short-term rise and a subsequent decline during most trials, sympathetic cardiac control initially decreased and then gradually rose. The coincidence of sympathetic inhibition and heart rate acceleration supports the notion that the sympathetic nervous system plays a subordinate role in the first acceleration/deceleration component of the cardiac defense response (Fernández & Vila, 1989; Reyes del Paso et al., 1994). Instead, heart rate acceleration is likely to be caused by a reduction of vagal outflow to the sinus node.
Stress and Cardiac Response

2010, Behaviour Research and TherapyCitation Excerpt :These differences were identified in the short- and long-latency acceleration/deceleration of the cardiac response. The short-latency component is vagally mediated (Reyes del Paso et al., 1993; Reyes del Paso et al., 1994), suggesting that reduced vagal reactivity may be the physiological mechanism underlying the potentiating effect of chronic worry on cardiac defence. Our results indicate that both intervention programmes were successful in reducing non-cued cardiac defence, presumably by the same physiological mechanism but in an opposite direction, i.e., by increase in vagal activation.
