“…As regards to the vasomotricity, there is a strong reactivity to stimuli, since the mean values of vasoconstriction varied between 14 and 27%, confirming other studies carried out in adults [35] and in neonates [6,25] in different various experimental conditions.…”

“…One of the specificity of our study was the fact that contrary to other studies [6,25], our population was explored in a supine position which is now recommended by every pediatric team as the prone position is linked to a decrease in heart rate variability, which could be responsible for increasing the risks of fatal reactions to obnoxious stimuli [55]. Furthermore, our technique of recording the signal in response to stimulation did not show high percentage of artifacts contrary to other study [47].…”

In order to assess the specific sympathetic reactivity in premature infants at term, we designed a study to evaluate the peripheral vasomotor response of such infants when exposed to auditory challenges. Testing was performed in 29 premature neonates at term in both quiet and active sleep during a morning session. Two types of noises were used (click and continuous tones) at three frequencies (250, 1,000 and 6,000 Hz) and at three intensities (60, 85 and 110 dBA). Vasomotor response was studied by analyzing with Mathlab^® software the variability of the plethysmographic wave of the oxymetric pulse. No behavioral awakening was observed in response to any stimulation. When a tachycardia or a bradycardia reaction to the stimuli was observed, all neonates responded with a vasoconstriction. The global mean of the vasoconstrictive response was 18.45%. The overall ANOVA on the vasomotor response revealed significant effects for sleep stages (t: 1.98; p < 0.05), for frequency (t: 3.3; p < 0.001) and for intensity of noise (t: 3.01; p < 0.03) but no significant response with heart rate variability. From these results, we could conclude that the assessment of the vasomotor response is a very sensitive procedure to determine the reactivity of the autonomic nervous system in neonates, and could be used to study such vegetative responses in other stressful situations with good accuracy.

“…Also, prenates of mothers who listened to 'soap opera' theme music during pregnancy showed a preference for the same music during the postnatal period (Hepper, 1988). The longer the prenatal exposure of human neonates, living in the Osaka airport neighbourhood, to airplane noises, the better they slept compared to babies whose mothers had lived in the area of the airport for shorter times during pregnancy (Ando and Hattori, 1977). The work of DeCasper and Fifer (1980), DeCasper and Spence (1986), DeCasper and Prescott (1984) reveals a complexity of bonding and language processing during the prenatal period.…”

Four experiments are described which investigated the role of the mother's voice in facilitating recognition of the mother's face at birth. Experiment 1 replicated our previous findings (Br. J. Dev. Psychol. 1989; 7: 3-15; The origins of human face perception by very young infants. Ph.D. Thesis, University of Glasgow, Scotland, UK, 1990) indicating a preference for the mother's face when a control for the mother's voice and odours was used only during the testing. A second experiment adopted the same procedures, but controlled for the mother's voice from birth through testing. The neonates were at no time exposed to their mother's voice. Under these conditions, no preference was found. Further, neonates showed only few head turns towards both the mother and the stranger during the testing. Experiment 3 looked at the number of head turns under conditions where the newborn infants were exposed to both the mother's voice and face from birth to 5 to 15 min prior to testing. Again, a strong preference for the mother's face was demonstrated. Such preference, however, vanished in Experiment 4, when neonates had no previous exposure to the mother's voice-face combination. The conclusion drawn is that a prior experience with both the mother's voice and face is necessary for the development of face recognition, and that intermodal perception is evident at birth. The neonates' ability to recognize the face of the mother is most likely to be rooted in prenatal learning of the mother's voice.
