Whose clock makes yours tick? How maternal cardiorespiratory physiology influences newborns’ heart rate variability

Changes in autonomic regulation due to Kangaroo care remain unaffected by using a swaddling device

“…In other studies, the sounds of heartbeats were reported to have a calming effect during caregiving procedures as measured by vital signs . Perhaps the stimuli employed by the swaddling device might have been of an insufficient intensity to overcome the background noise or olfactory stimuli of the NICU . Furthermore, nasal blockage or the use of masks, tubes and patches meant for respiratory support may hinder the sense of smell in preterm infants.…”

Childhood Adversity and Affective Touch Perception: A Comparison of United Kingdom Care Leavers and Non-care Leavers

“…Maternal touch is known to have a significant influence on the developing autonomic system ( Hofer, 1994 ; Field et al, 1995 ; Van Puyvelde et al, 2019b ). While, both skin-to-skin contact with their mother and stroking touch increase respiratory sinus arrhythmia (RSA), a component of HRV, in young infants ( Van Puyvelde et al, 2015 , 2019a , b ), lack of parental support is known to lead to blunted RSA development ( Field et al, 1995 ). To the best of our knowledge, differences in somatosensory processing in those raised in foster care have not previously been reported.…”

Toward Interactive Social Neuroscience: Neuroimaging Real‐World Interactions in Various Populations

“…Coherent physiological signals have also been observed for mother and infant. Specifically, cardiorespiratory activity was demonstrated to be synchronized between mother–infant dyads while infants lay on the mother's body (Van Puyvelde et al, ). Such synchronization is thought to be triggered by subtle perceptual cues, including eye gaze, subtle facial movement, and breathing, which may be processed implicitly.…”
