Summary
My proposed research program involves several distinct yet related projects addressing i) early detection and ii) early intervention for infants at high risk of movement problems including cerebral palsy. This research will provide the highest quality evidence base that is needed to identify those children most at risk early in development and improve our understanding of which interventions are most effective, so that scare health care resources can be targeted appropriately.
Developmental Programming: Mechanisms And Interventions

Summary
Disturbances during pregnancy can impact on developmental processes and result in increased risk of disease in later life. This project will examine the impact of perturbations such as maternal stress or alcohol consumption on the development of the placenta and fetal kidney. By gaining an understanding of how these organs are affected by prenatal insults, we are likely to be able to develop more effective intervention strategies to ensure all babies receive a healthy start to life.
Asking QUestions About Alcohol In Pregnancy (AQUA): Longitudinal Cohort Study Of The Effects Of Low And Moderate Doses Of Alcohol Exposure On The Fetus

Summary
National alcohol guidelines advise women to have no alcohol in pregnancy. However, many find they are unexpectedly pregnant and have been drinking, leading to considerable anxiety. While evidence is clear that heavy drinking is bad for the unborn baby, no-one knows for sure if low or even moderate levels of alcohol in pregnancy are harmful. We will study this important public health problem, following a group of pregnant women through their pregnancy and until their child is two years.
Periconceptional Alcohol Exposure: Effects On The Embryo And Fetus And Disease Risk In Adulthood

Summary
It is known that consuming large amounts of alcohol during pregnancy can have deleterious effects on fetal growth and development. Less is known about the effects of consumption of alcohol just around the time of conception. This project will use animal models to explore if alcohol can alter development of the very early embryo and whether this has long term consequences for the health of offspring after birth.
The Role Of Hypoxia In The Developmental Programming Of The Kidney

Summary
We aim to understand how inadequate oxygen supply to the fetus during pregnancy can affect development of the kidney. Many babies do not get enough oxygen whilst developing in the womb. This can be due to a poorly formed placenta or the mother smoking. This can interfere with normal growth and formation of the kidney. Our knowledge may help babies get the best start to life.

Summary
During pregnancy, the surface of the fetal brain gradually develops the ridges, valleys, and folds that are the characteristic feature of our highly developed brain. However, this process can be disturbed if birth occurs prematurely, the unborn baby suffers oxygen starvation in the uterus, or the mother consumes alcohol. In this project we are determining how cell migration results in the development of brain surface folding, and how hypoxia and maternal alcohol consumption affect these importan ....During pregnancy, the surface of the fetal brain gradually develops the ridges, valleys, and folds that are the characteristic feature of our highly developed brain.

Development Of The Commissural Plate And Its Role In Forebrain Commissure Development

Summary
During development, neurons in one hemisphere of the brain connect and communicate with neurons in the opposite hemisphere. Such neural connections between the two hemispheres are called commissures, which are large bundles of axons (neural-wires) that cross the midline of the brain. There are three commissures in the forebrain: the corpus callosum, the hippocampal commissure and the anterior commissure. This wiring of the brain is essential to its proper function. When these connections don't f ....During development, neurons in one hemisphere of the brain connect and communicate with neurons in the opposite hemisphere. Such neural connections between the two hemispheres are called commissures, which are large bundles of axons (neural-wires) that cross the midline of the brain. There are three commissures in the forebrain: the corpus callosum, the hippocampal commissure and the anterior commissure. This wiring of the brain is essential to its proper function. When these connections don't form, the brain cannot integrate and process information in fundamental ways. Over 50 different human congenital disorders are associated with the malformation of one or more of these forebrain commissures. This proposal investigates the hypothesis that a midline structure, called the commissural plate (CP), regulates the development of all forebrain commissures. The CP was first described anatomically at the turn of the 20th century in a number of different species, and in humans in 1968. However, since this time, no papers have been published on the CP. Experiments in this proposal will use modern neuroanatomical techniques, particularly magnetic resonance imaging, molecular and mouse mutagenesis techniques, and axon guidance assays, to study the CP. We will test the hypothesis that there is something fundamentally unique about the CP as the midline crossing point for all commissural axons. We generate mouse mutants that disrupt only dorsal CP formation and then determine whether the subsequent development of the dorsal commissures occurs. We also perform molecular expression, and imaging analyses on human foetal brains. Our goal is to provide an understanding of what developmental events are disrupted in human congential disorders resulting in midline brain malformations and agenesis of the forebrain commissures. Understanding the basis of these disorders will lead to more accurate diagnoses and potentially their prevention through genetic counseling.Read moreRead less
