OBJECTIVE: Previous infant studies investigated neural mirroring during the observation of live or video actions. However, both methods have their (dis)advantages and studies using one of these methods are not always directly comparable. Therefore, the present study directly compared neural mirroring activity in a video setting with a live setting ...

Infant faces elicit early, specific activity in the orbitofrontal cortex (OFC), a key cortical region for reward and affective processing. A test of the causal relationship between infant facial configuration and OFC activity is provided by naturally occurring disruptions to the face structure. One such disruption is cleft lip, a ...

A recent study has found that carrying - not just holding - by human mothers has a specific calming effect on crying infants, inducing a coordinated physiological response that includes a reduction in heart rate. A similar response in mice has opened the door to elucidating the underlying neural mechanisms.

Motivation to move has typically been a post hoc explanation for infants' discovery of new patterns of behavior. As a first step to studying motivation to move directly, we qualitatively assessed motivation to move and measured its relationship to motor development in infancy. We observed 27 infants longitudinally from ages ...

PURPOSE: The aim of this study was to evaluate the results of a conservative intervention in infants with plagiocephaly according to their specific clinical profile. METHODS: Prospective clinical trial in which 104 infants with plagiocephaly accompanied or not by congenital or positional torticollis were referred to Early Care and Monitoring ...

The development of reaching and of sitting during the first year of life is typically studied as separate yet related behaviors. Interestingly, very soon after learning to reach, 4-7-month-old infants start coordinating their arms with their trunk and legs for sitting. In this longitudinal study, we focused, for the first ...

The purpose of this study was to investigate the factors underlying the ability to plan object-oriented grasping movements in the first two years of life. In particular, we were interested in evaluating the relationship between manual motor planning, object use and infant-parent interaction. In order to achieve this aim, grasping ...

Infants have a sophisticated behavioral and cognitive repertoire suggestive of a capacity for conscious reflection. Yet, demonstrating conscious access in infants remains challenging, mainly because they cannot report their thoughts. Here, to circumvent this problem, we studied whether an electrophysiological signature of consciousness found in adults, corresponding to a late ...

BACKGROUND: Mother-infant bonding is the earliest and most critical social relationship of mammalian infants. To promote this bond, infants have innate behaviors to seek maternal proximity and protest upon separation via communication with the mother vocally and through body movement. However, the physiological mechanisms regulating these infant behaviors remain largely ...

This study aimed to determine the prevalence and early outcome of neural tube defects (NTDs) in Malaysia. This prospective study included all neonates with NTDs (spina bifida, anencephaly, encephalocoele) born in 2009 in 32 Malaysian hospitals in the Malaysian National Neonatal Network. The prevalence of NTDs was 0.42 per 1000 ...

During infant development, objects and their functions are learned by means of active exploration. Factors that may influence exploration include reaching and grasping ability, object properties and the presence of developmental disorders. We assessed the development of exploratory actions in 16 typically-developing (TD) infants and 9 infants with Down syndrome ...

The development of grasping is an important milestone that infants encounter during the first months of life. Novel approaches for measuring infants' manual actions are based on sensorized platform usable in natural settings, such as instrumented wireless toys that could be exploited for diagnosis and rehabilitation purposes. A new sensorized ...

Mouse models with prenatal alterations in dopaminergic functioning can provide new opportunities to identify fetal behavioral abnormalities and the underlying neural substrates dependent on dopamine. In this study, we tested the hypothesis that prenatal loss of nigrostriatal function is associated with fetal akinesia, or difficulty initiating movement. Specific behaviors were ...

A comprehensive understanding of the mechanisms that underlie brain development in premature infants and newborns is crucial for the identification of interventional therapies and rehabilitative strategies. fMRI has the potential to identify such mechanisms, but standard techniques used in adults cannot be implemented in infant studies in a straightforward manner. ...

During the weaning period, infants are not skilled at self-feeding and caregivers play a prominent role in feeding. Therefore, solid feeding is an inherently collaborative and interactive process between caregivers and infants. The present study examined how caregivers and infants coordinate to construct solid feeding interactions, as an analysis of ...

Recently, our laboratory has shown that the neural mechanisms for encoding lexico-semantic information in adults operate functionally by 12-18 months of age within left frontotemporal cortices (Travis et al., 2011. Spatiotemporal neural dynamics of word understanding in 12- to 18-month-old-infants. Cereb Cortex. 8:1832-1839). However, there is minimal knowledge of the ...

Doppler CBFV parameters (peak systolic velocity [PSV] and mean velocity [MV]) of the bilateral middle cerebral arteries of 52 healthy term infants were prospectively examined ...

Rational action understanding requires that infants evaluate the efficiency of a movement in achieving a goal with respect to situational constraints. In contrast, recent accounts have highlighted the impact of perceptual characteristics of the demonstrated movement or constraints to explain infants' behavior in so-called rational imitation tasks. The current study ...

OBJECTIVES: Dioxin levels in the breast milk of mothers residing near hot spots of dioxin contamination areas in South Vietnam remain much higher than in unsprayed areas, suggesting that fetuses and breast-fed infants may be exposed to high levels of dioxins. The present study investigated the association of infant neurodevelopment ...

Vitamin D intoxication in infancy leads to acute hypercalcemia and subsequent hypercalcuria with nephrocalcinosis. Strategies used for patients with vitamin D intoxication are unsatisfactory and associated with prolonged periods of hypercalcemia. We present a 5-month-old infant who had failure to thrive, refusal to feed, delayed motor development, truncal hypotonia, and ...

Premature infants are at risk for adverse motor outcomes, including cerebral palsy and developmental coordination disorder.

Chlordecone is a persistent organochlorine pesticide that was used in the French West Indies until the early 1990s for banana weevil borer control. Human exposure to this chemical in this area still occurs nowadays due to consumption of contaminated food. Although adverse effects on neurodevelopment, including tremors and memory deficits, ...

Depressed mothers show negatively biased responses to their infants' emotional bids, perhaps due to faulty processing of infant cues. This study is the first to examine depression-related differences in mothers' neural response to their own infant's emotion faces, considering both effects of perinatal depression history and current depressive symptoms. Primiparous ...

Background. The etiology of motor impairments in preterm infants is multifactorial and incompletely understood. Whether corpus callosum development is related to impaired motor function is unclear. Potential associations between motor-related measures and diffusion tensor imaging (DTI) of the corpus callosum in preterm infants were explored. Methods. Eight very preterm infants ...

INTRODUCTION: Infants with asymmetric brain lesions are at high risk of developing congenital hemiplegia. Action-observation training (AOT) has been shown to effectively improve upper limb motor function in adults with chronic stroke. AOT is based on action observation, whereby new motor skills can be learnt by observing motor actions. This ...

Burr-hole craniostomy is the most efficient and safe choice for surgical drainage of chronic subdural hematoma (CSDH). Although the twist-drill drainage is also relatively safe and time-saving, it carries the risk of inadequate drainage, brain penetration and hematoma formation. Our modified technique helps in avoiding bleeding and brain penetration. MATERIAL ...

Objective: To determine if the degree of congenital, idiopathic microcephaly in a female infant was congruent with the degree of developmental motor delay she exhibited. Methods: A 6.5-month-old female infant with idiopathic microcephaly was referred for evaluation due to parental concerns about possible cerebral palsy. She was assessed with two ...

Improved understanding of how the human brain is "wired" on a macroscale may now be possible due to the emerging field of MRI connectomics. However, mapping the rapidly developing infant brain networks poses challenges. In this study, we applied an automated template-free "baby connectome" framework using diffusion MRI to non-invasively ...

BACKGROUND: Whereas considerable work has been published regarding biological factors associated with infant health, much less is known about the associations of environmental context with infant development - the focus of the present cross-sectional study. METHODS: Data was collected on 561 infants, aged newborn to 18 months. Measures included the ...

Recently, researchers have been debating whether infants' selective imitative learning is primarily based on sensorimotor processes (e.g., motor resonance through action perception) or whether inferential processes such as teleological reasoning (i.e., reasoning about the efficiency of others' actions) predominantly explain selective imitation in infancy. The current study directly investigated two ...

The vocalizations and jaw kinematics of 30 infants aged 6-8 months were recorded using a Motion Analysis System and audiovisual technologies. This study represents the first attempt to determine the effect of play environment on infants' rate of vocalization and jaw movement. Four play conditions were compared: watching videos, social ...

Former preterm and very low birthweight infants require close neurodevelopmental surveillance after hospital discharge, but in-person professional testing is resource-intensive and inconvenient for families. A standardised developmental questionnaire completed by parents offers an alternative to in-person testing, but few such questionnaires have been validated. Our aim was to validate the ...
