Nos conférenciers invités
Mercredi 20 novembre 2024, Conférence grand public (en français, ouverte à tous) "Génomes anciens, enfances perdues : Retracer la vie des jeunes dans les sociétés du passé"
Jeudi 21 novembre 2024, Conférence invitée (ouverte aux participants du colloque uniquement) "How muscles shape the growing skeleton"
Due to the short levers muscles work with, the skeleton experiences large muscle forces equivalent to several times bodyweight during physical activity. Bones readily adapt their size, shape, and structure in response to this loading. For example, adolescent tennis players have 40% more bone in their racquet than non-racquet arm, whilst children born breech (and therefore less able to load the skeleton through kicking) have 10° higher femoral anteversion. Prenatal movements, and those associated with acquisition of motor milestones in infancy, appear to have large, persistings effect on skeletal development. In addition, the pattern of bone adaptation to loading seems highly sex and maturity specific, and for some parameters is maintained decades after cessation of activity. Therefore physical activity at different stages of childhood may leave distinct evidence in skeletal remains, even in those individuals who reached adulthood.
In this talk, I will present findings from study of living models of human loading and skeletal health across the lifespan by our group and other colleagues in the field. We will discuss how new techniques and findings in contemporary living populations can confirm and validate archaeological research into children’s lives, and in turn how archaeological study can inform modern science and medicine.
Vendredi 22 novembre 2024, Conférence invitée (ouverte aux participants du colloque uniquement) "The influence of the maternal environment on fetal learning" The intra-uterine environment offers the fetus a multitude of vestibular, tactile, somato-sensory, auditory, vocal, musical, rhythmic and even multi-modal stimuli. All these stimuli can vary according to the mother's activities. In the same environment, the fetus is able to perceive this wide range of stimuli, process the information, store it in its memory and discriminate between it and a new stimulus. It is also able to produce numerous motor actions, both rhythmic and non-rhythmic. The foundations of learning and memory are laid in intra-uterine life. We will also look at the role of sensory-motor synchronization in interaction and communication. |
