Full textDiffusion tensor MRI enables to explore the cerebral microstructure non invasively by measuring the water molecules movements. Whereas the anisotropic organization of white matter fascicles has been revealed using this method in adults, their structure has not been detailed yet in the developing brain, and the biological origins of the diffusion index changes with age remain controversial. This thesis thus aimed at imaging the healthy infant white matter in order to study its early organization and to provide an in vivo monitoring of its postnatal maturation. A dedicated acquisition protocol was first implemented and applied to twenty-three one- to four-months-old unsedated babies, and an algorithm which generates the diffusion orientation distributions was adapted for acquisitions corrupted with motion. Major fiber bundles were then identified and reconstructed by tractography despite their unachieved myelination. Moreover, several quantification approaches were investigated. In an inter-individual study, monitoring the index with age led us to suggest a classification of the differential bundles maturation, in agreement with the post mortem knowledge of its spatio-temporal progression. In an intra-individual study, inter-hemispherical asymmetries, consistent with the adult functional specialization, were outlined. Besides, the diffusion structural informations were correlated with functional measurements by evoked potentials for the visual system. Consequently, the methodology we used seems promising for our improved understanding on the infant development

Full textThis thesis examines how the inverse effectiveness principle can be applied to the olfactory-to-visual interaction during infant development using fast periodic visual stimulation (FPVS) with a frequency-tagging approach in scalp electroencephalography (EEG). In particular, we have tried to confirm this principle based on the developmental improvement of vision (Study 1) and different visual demand at a given age (Study 2 and 3) as it was shown that infant visual perception can be facilitated by the reception of odor cues.We observed that a facilitation effect of maternal body odor on rapid face categorization gradually declines with the progressive maturation of the visual system from 4 to 12 months (Study 1), showing a developmental trade-off between vision and olfaction. This suggests that the strength of the odor effect is linked to the strength of the face-selective response, elicited here using quite complex naturalistic stimuli. Thus, in Study 2, we manipulated visual demand (i.e., simplifying the stimuli) in 4 month-old infants and found a stronger face-selective response in the less demanding categorization that led to the suppression of the odor effect. Taking in account the effective face categorization in 12-month-old brain linked with visual development, in Study 3, we instead increased visual demand by doubling the image presentation rate. As expected, a weaker face-selective response was measured, however the odor effect did not increase but rather reduced the response, suggesting a sensory overload.Overall, this dissertation demonstrates for the first time the application of the inverse effectiveness principle to olfaction during perceptual development, through Study 1 and 2. The stronger face-selective response (due to the sufficient maturation level of vision or decreased visual demand) leads to the weakest olfactory-to visual interaction (i.e. intersensory facilitation), however the low face-selective response not always links to the enhanced odor effect: only when visual system is not enough developed in the early infancy

Full textThe quality of lipids in infant formula is essential, especially in terms of polyunsaturated fatty acids (PUFAs) such as arachidonic acid (ARA) and docosahexaenoic acid (DHA). These could promote the neurosensory development of the child. We thus evaluated 4 commercial standards containing plant or dairy lipids and supplemented or not with ARA / DHA, on the neurosensory development through an artificially feeding model "pups in the cups". In PET-cs, we observe that the supplementation in ARA / DHA makes it possible to normalize the cerebral functioning. The exploration of tissue lipids indicates differences in DHA which are particularly low with pure plant lipids intake. We propose an algorithm for predicting cerebral and ocular DHA via erythrocyte fatty acids profiles. In these tissues one-third of the DHA species are affected and correlated with brain activity. The neuromediators resulting from AL, ARA, DHA by the LOX pathway are impacted as well as the spatial distribution of DHA in IMS imaging. Other omics data underlined the impact of lipid background x combination DHA / ARA (transcriptomics) or lipid background (metabolomics) on the regulation of cerebral metabolism impacting neuronal metabolism and brain metabolism of the microbiota probably through the signalling of gut-brain axis. We then identify a metagenome sensitive to the addition of DHA / ARA correlated to brain function. Finally, epigenetic modifications (methylation of the genome and miRNA) affecting the FC group potentially suggest a long-term impact

Full textNowadays, a high rate of infants is still being fed infant formulas (IF) based on cow milk and subjected to several technological treatments. These substitutes aim to mimic as close as possible the human milk (HM). Despite of IF improvement, differences still exist between HM and IF in terms of composition and structure, and effects on health in infancy, and later on in adulthood. The objective of this work was to understand how the infant food modulated the dietary nitrogen digestibility and, in overall, how it shaped the microbiota-gut-brain axis. Two infant models were used and compared, the 16 to 21-day-old mini-piglet Yucatan and an in vitro dynamic digestion model parametered with term infant digestive conditions. Digestive contents and tissues were then analyzed using metagenomic (microbiota), histological and ex vivo permeability (intestinal physiology) approaches, gene expression and targeted-metabolomic approaches (intestine, brain and plasma). The results showed that the digestibility of nitrogen and at least extent, that of a few amino acids (Lys, Phe, Thr, Val, Ala, Pro and Ser) were different between HM and IF. The two digestion models (in vivo and in vitro) led to similar observations in terms of meal deconstruction and proteolysis, showing that the in vitro dynamic digestion model is a good proxy of the in vivo digestion regarding digestion kinetics. The microbiota-gut-brain axis, notably regarding the colonic microbial composition and the tryptophan metabolism, which digestibility was similar between infant foods, were differently modulated by HM and IF. The increase of the intestinal permeability, though moderately, was associated with a boost of the intestinal immune system and changes in gene expression (barrier and endocrine functions, volatile fatty acids receptors) at hypothalamic and striatal levels and with changes in hippocampal and plasma metabolomic profiles. Some components present in HM (e.g.: oligosaccharides, non-protein nitrogen such as urea, bacteria consortia) and absent in IF can explain the discrepancies observed. IF-supplementation with these bioactive components and/or with the modulation of the protein profile would be of interest for further investigation

Full textNewborns not only recognize their mother tongue at birth but are also capable of distinguishing far better than their mothers the totality of sounds of languages spoken on earth. What is the particular organization of the human brain that permits such linguistic abilities? During my Ph. D. , I studied language areas in the brain’s anatomy to better understand the early acquisition of language in life. Anatomy was described and analyzed by using magnetic resonance images (MRI) on infant brains. With the help of Neurospin research teams, I built the following methodological tools: We first proposed a cortical segmentation framework to deal with the weak image contrast during the first months of life. This method is based on several image properties of tissues and requires no atlas. Two initial segmentations, which are set on each side of the cortex, are deformed so as to converge at the gray-white matter interface. Segmentation results were very good for younger infants, i. E. , neonates (Dice coefficient = 0. 89). Then, we defined a maturation index based on the cortical image intensity. As it was expected, the index strongly increased with age in every region of interest (R2=0. 88). Index variations are most likely due to a decrease of water content related to membrane proliferation. In MR images, we manually drew cortical sulci within language areas. We then measured asymmetry and maturation indices along these sulci. Early organization was found in language areas close to the one reported in adults for both indices. A little-known depth asymmetry was found at the superior temporal sulcus. The deepest part of this sulcus onthe right hemisphere might be a lifelong landmark, whereas the shallower left sulcus would be related to a more segmented pattern. Also, we characterized the early forward and upward shift of the posterior end of the right Sylvian fissure. Moreover we confirmed the asymmetrical sizes of both the planum temporale and the Heschl’s gyrus. These asymmetries might be related to a larger connectivity in the left areas as well as to interhemispheric differences in processing auditory stimuli, specifically speech. As for the maturation index, the index value of the Broca’s area was far from being the lowest among language areas, which is at odds with the common opinion that prefrontal regions are immature at birth. We also reported a decrease of the maturation index along a dorso-ventral axis in the temporal lobe, consistent with the hierarchical organization of linguistic processes. Last of all, maturation indices of both Broca’s area and the posterior part of the superior temporal sulcus were correlated with another developmental index (fractional anisotropy) in the arcuate fasciculus. This correlation suggests the early development of the linguistic dorsal pathway between Broca’s area and temporo-parietal regions. We discuss in the end the genetic origins and mechanisms of this organization, suggesting that some innate modules might be dedicated to process speech. The results presented in this thesis bring further questions: if the asymmetry of the superior temporal sulcus means a more segmented pattern on the left hemisphere, what are the consequences of such segmentation on the linguistic processes? Furthermore, what role does the dorsal pathway play in language lateralization?

Full textThe environment (E) of very preterm infant (VPI) greatly differs from the uterine E and contributes to his risk of altered neurodevelopment. Although auditory stimuli are prominent and atypical in the NICU, little is known about the auditory sensitivity of VPI to his acoustic E. It is evaluated through their physiological, behavioral, and brain (NIRS) responsiveness to auditory environmental changes. An observational study shows that i) VPIs respond to “naturalistic” auditory stimuli from a minimum signal-to-noise ratio threshold of 5-10 dBA, ii) some stimuli can affect their well-being (desaturation, sleep disruption), iii) their autonomic reactivity is the most sensitive. Their reactivity varies depending on the sound sources, suggesting an ability to discriminate vocal from non vocal sounds. An experimental approach assess other aspects of their auditory performance (impact of sound frequency, emotional valence of voices) and their maturation from 30-32 to 34-36 wks post-menstrual age. Their perceptual field of sound frequencies expands for pure tones from the middle frequencies (500-2500 Hz) to low and high frequencies (100 and 4500 Hz). After 34 wks, VPIs discriminate their mother's voice from that of another mother and of another woman (emotionally neutral). This preferential reactivity relies on a "cardiac orienting reflex" suggesting that VPI not exposed for weeks to their mother’s voice in utero, can develop perceptual abilities similar to those of the fetuses continuously exposed to the prosody of their mother’s voice. They open ways for further research on the long-term consequences of early auditory experience (attachment, language and emotions development)
