“…Depending on how long the fetus was observed after stimulation, motor responses have been observed in fetuses between 26 to 33-gestational weeks (Gagnon et al, 1987; Kisilevsky et al, 1992; van Heteren et al, 2000). Previous studies utilizing fetal ultrasound have classified movement as a change in fetal activity, with only two studies examining specific movement type or quality; one documenting the occurrence of the startle reflex (Groome et al, 1995); and one documenting eye and mouthing movements (Morokuma et al, 2004). Improved understanding of the quality of movements occurring following VAS stimulation may provide additional insight into not only the ability of the fetus to react, but also the quality and stability of motor skills.…”

Background: Ultrasound observation of fetal movement has documented general trends in motor development and fetal age when motor response to stimulation is observed. Evaluation of fetal movement quality, in addition to specific motor activity, may improve documentation of motor development and highlight specific motor responses to stimulation. Aim: The aim of this investigation was to assess fetal movement at 26 and 36-weeks gestation during three conditions (baseline, immediate response to vibro-acoustic stimulation (VAS), and post-response). Design: A prospective, longitudinal design was utilized. Subjects: Twelve normally developing fetuses, eight females and four males, were examined with continuous ultrasound imaging. Outcome Measures: The fetal neurobehavioral coding system (FENS) was used to evaluate the quality of motor activity during 10-s epochs over the three conditions. Results: Seventy-five percent of the fetuses at the 26-week assessment and 100% of the fetuses at the 36-week assessment responded with movement immediately following stimulation. Significant differences in head, fetal breathing, general, limb, and mouthing movements were detected between the 26 and 36-week assessments. Movement differences between conditions were detected in head, fetal breathing, limb, and mouthing movements. Conclusion: Smoother and more complex movement was observed with fetal maturation. Following VAS stimulation, an immediate increase of large, jerky movements suggests instability in fetal capabilities. Fetal movement quality changes over gestation may reflect sensorimotor synaptogenesis in the central nervous system, while observation of immature movement patterns following VAS stimulation may reflect movement pattern instability.

“…Kisilevsky & Muir, 1991). Moreover, since the responsivity to vibroacoustic stimulation follows a specific maturational time line across gestation (Hoh, Park, Cha, & Park, 2009), any perturbation of the pattern of responses elicited by this kind of stimulation is thought to have a relevant diagnostic function during complicated pregnancies (D'Elia, Pighetti, Vanacore, Fabbrocini, & Arpaia, 2005;Morokuma et al, 2004). It is plausible that the presentation of stimuli in close temporal proximity could support the deployment during later development of the favored processing of specific co-occurring crossmodal sensory inputs (see Lecaunet & Schaal, 1996).…”

Audiotactile interactions in temporal perception

In the present review, we focus on how commonalities in the ontogenetic development of the auditory and tactile sensory systems may inform the interplay between these signals in the temporal domain. In particular, we describe the results of behavioral studies that have investigated temporal resolution (in temporal order, synchrony/asynchrony, and simultaneity judgment tasks), as well as temporal numerosity perception, and similarities in the perception of frequency across touch and hearing. The evidence reviewed here highlights features of audiotactile temporal perception that are distinctive from those seen for other pairings of sensory modalities. For instance, audiotactile interactions are characterized in certain tasks (e.g., temporal numerosity judgments) by a more balanced reciprocal influence than are other modality pairings. Moreover, relative spatial position plays a different role in the temporal order and temporal recalibration processes for audiotactile stimulus pairings than for other modality pairings. The effect exerted by both the spatial arrangement of stimuli and attention on temporal order judgments is described. Moreover, a number of audiotactile interactions occurring during sensory-motor synchronization are highlighted. We also look at the audiotactile perception of rhythm and how it may be affected by musical training. The differences emerging from this body of research highlight the need for more extensive investigation into audiotactile temporal interactions. We conclude with a brief overview of some of the key issues deserving of further research in this area.Keywords Auditory . Tactile . Temporal . Frequency . Audiotactile . Crossmodal similarities . Mechanoreception . MultisensoryThe boundaries between hearing and touch: the foundation of an analogyWe continuously interact with environments that provide a large amount of multisensory information to our various senses. Researchers have now convincingly demonstrated that the inputs delivered by the different sensory channels tend to be bound together by the brain (see the section Research on hearing and touch: a multisensory perspective for a fuller discussion of this topic). Unlike the audiovisual and visuotactile sensory pairings, those interactions taking place at both the neuronal and behavioral level between audition and touch have, to date, been explored in far less detail (see Kitagawa & Spence, 2006;Soto-Faraco & Deco, 2009, for reviews of the extant literature). The paucity of research covering this modality pairing is rather surprising when one considers the wide range of everyday situations in which we experience-even though often in subtle and unconscious ways-the interplay between these two senses. Examples include perceiving the "auditory" buzzing and the itchy "tactile" sensation of an insect landing on the back of our neck; reaching for a mobile phone ringing and vibrating in our pocket. What is common to these situations is the exclusive-or, at the very least, predominant-reliance on cues provided by the

“…As the fetus develops, fetal movements of the face, limbs and torso are correlated with the structural development of CNS [15], demonstrating that the connection between cerebral cortex and peripheral structures of the fetus are functional. In addition to simple muscle movements, cerebral cortex functions are developed to facilitate learning in the fetus prenatally [15]. Also in compromised fetuses, development progresses with gestation, although progress is at variance with that in healthy fetuses, indicating that fetal facial movements may serve as a marker for normal development [16,17].…”

Objective: To determine whether Fetal Growth Restriction (FGR) fetuses have less facial expressions than Appropriate-for-Gestational Age (AGA) counterparts with the assessment by four-dimensional high-definition live (4D HDlive) ultrasound.Methods: 4D HDlive ultrasound examinations of fetal facial expressions were performed on singleton pregnant women between 26 and 39 weeks of gestation. The duration of the 4D HDlive recordings was 15 minutes in all cases. The frequency of seven types of previously-reported facial expressions, or blinking, mouthing, yawning, tongue expulsion, sucking, smiling and scowling, were assessed. Two observers counted the frequencies, and inter-and intra-observer reproducibility was examined. Wilcoxon rank-sum test was used for comparison of FGR and AGA group. Kruskal-Wallis test was used for intra-group significance of frequencies of seven types of fetal facial expressions. P<0.05 was considered significant. Results:In this study, good intra-and inter-class correlation coefficients and intra-and inter-observer agreements were obtained. Thus, measurement values by only one examiner were used for further analysis. The facial expressions of 16 fetuses (FGR: n=8, AGA: n=8) were assessed. We noted a tendency for FGR fetuses to have less facial expressions than AGA counterparts. Although statistically significant inter-group difference was not detected in frequency of any facial expressions, this propensity is conspicuous in smiling (p=0.065) and mouthing (p=0.279). In AGA fetuses, the commonest facial expression was mouthing and was significantly more frequent than blinking (p=0.007), tongue expulsion (p=0.007) and sucking (p=0.002). We also noted a tendency that the frequency of facial expressions declines with fetal maturation. Although no statistically significant difference was shown, this propensity is prominent in mouthing of FGR (p=0.071). Conclusion:4D HDlive ultrasound provides promising modalities in novel evaluative imaging of fetal various facial expressions, and may help to elucidate functional development of Central Nervous System (CNS) and facial expressions both in normal and compromised fetuses.
