Texte intégralThis 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

Texte intégralPrenatal stress is a subject of growing ethological interest due to its effects on human health and animal welfare. This Ph.D. thesis utilizes the cuttlefish Sepia officinalis, a convenient model in which developing offspring can be separated from their mothers to examine various potential sources of stress in experimental isolation. Several categories of stressors were applied to cuttlefish and cuttlefish eggs and the resulting offspring were tested in a range of physiological and behavioral tests. The goal was to determine if various types of prenatal stress affect cuttlefish, and if so, how these effects are transmitted. The data presented demonstrate that both stressors applied to reproducing females (maternal stress), as well as stressors applied directly to embryos (embryonic stress), affected post-natal behavior (including body patterning, brain lateralization, predation and activity patterns), learning, memory and/or neurobiology (including monoamine concentrations and turnover, the size of various brain lobes and cell division). The results highlight the presence of three pathways by which stress can exert effects: on the number of offspring produced by the female, transmission from the female to her offspring and directly on the offspring themselves. The experiments also demonstrated that a completely artificial stressor (bright light) affected a wider range of behaviors in offspring than a natural-occurring one (predator odor). Finally, the data showed that incubation and spawning environment can also affect offspring, and thus deserve attention in the formulation and interpretation of experiments with this species. These findings inform both welfare practices for cuttlefish and other cephalopods (e.g. reduce handling to maximize reproduction) as well as elucidating and reinforcing ethological principles that apply to animal stress in general (e.g. the transmission of stress effects from mother to offspring). Given the insight provided here and in numerous other studies, cuttlefish and other cephalopods should continue to serve as behavioral models in ethology and biology in general

Texte intégralPreterm neonates experience many painful procedures during their hospitalisation in the Neonatal Intensive Care Unit (NICU) where heel prick is the most frequent painful intervention. Repeated and untreated pain has long term consequences for preterm neonates. The use of pharmacological and non-pharmacological pain management interventions is limited for preterm neonates. Therefore, it is essential to investigate new pain management interventions such as breast milk odor. This pilot study aimed to evaluate the feasibility and acceptability of an olfactive stimulation intervention to manage procedural pain of preterm neonates, born between 28 and 34 weeks of gestation, during heel prick. A pilot study was conducted with 12 preterm neonates, 11 mothers and 20 nurses in a level III NICU. The study group was familiarised with breast milk odor for nine hours preceding blood sampling. Breast milk odor was combined with standard care during heel prick and pain was measured by the Premature Infant Pain Profile-Revised. Self-reported questionnaires administered to mothers (n = 11) and nurses (n = 20) confirmed the feasibility and acceptability of the intervention, with a proportion of over 80% for both of these items. Observed effect indicated that the closer the compress with the breast milk odor was to the preterm neonates’ nose (n=12), the shorter time to return to baseline after the painful procedure was and the lower the pain score was on the PIPP-R. Breast milk odor is a non-pharmacological pain management intervention which is non-expensive and feasible for mothers and nurses. Findings of this pilot study guide the methodology of a randomized controlled trial.
