Summary
Cerebral palsy is the most common cause of physical disability in children affecting 1 in 500 young Australians. While the brain lesion is static, the musculoskeletal problems are progressive and require lifelong management (cost of US$946,000 over life per person).

While the brain lesion is static, the musculoskeletal problems are progressive and require lifelong management (cost of US$946,000 over life per person). Only large prospective population-based studies give a true indication of the incidence of physical problems, determine the pathway(s) to outcome and determine the best pathways to successful treatment and efficient resource allocation. The broad aim of this project is: This population based cohort study (n - 240) aims to determine the pathway to motor outcome from diagnosis at 18 months to 5 years based on the nature of the brain injury at 24 months (structural MRI of the nature, location and timing of the brain lesion). Secondary Aims: Determine the rate of musculoskeletal deformity (hip displacement, spasticity, muscle contracture). Potential impact of medical co-morbidities (nutrition, epilepsy, respiratory problems) Patterns of participation and HRQOL. Patterns of medical resource use: treatment costs and outcomes. This study will: Allow clinicians to better the likely functional outcomes of children with CP from an earlier age based on the rate and limit of gross motor development and nature and severity of the brain lesion, determine the nature and timing of physical deformities to aid prevention and treatment; provide information on resource use for future planning and organisation of medical and therapy services. This in turn will give more accurate prognostic counseling as well as target areas for early therapy. Our multidisciplinary research group is uniquely placed to conduct this world-first study with access to two entire birth years of children linked to our Victorian Cerebral Palsy Register. Recruitment is conducted at both the Royal Children's Hospital and the Monash Medical centre in order to ensure state wide referral and easy access for families.Read moreRead less

Summary
The Centre for Clinical Research Excellence in Newborn Medicine will study adverse outcomes for the brains and lungs of newborn babies; it will establish how often these occur in different types of babies (ranging from very premature babies, through to those born on time), investigate the different causes, develop treatments to either prevent or treat the adverse outcomes, determine the long-term consequences into adulthood, and continually re-evaluate the effectiveness of the various treatment ....The Centre for Clinical Research Excellence in Newborn Medicine will study adverse outcomes for the brains and lungs of newborn babies; it will establish how often these occur in different types of babies (ranging from very premature babies, through to those born on time), investigate the different causes, develop treatments to either prevent or treat the adverse outcomes, determine the long-term consequences into adulthood, and continually re-evaluate the effectiveness of the various treatment strategies designed to improve the health outcomes for newborn babies.Read moreRead less
Delayed Radial Glial Maturation Linked To NFI Deficiency As An Underlying Cause Of Cortical Defects In Humans And Mice

Summary
The timely generation of neurons and glia is important for brain development and consequently brain function throughout life. Nuclear factor I (NFI) genes are important for regulating the production of neurons and glia, and people with disrupted NFI genes have severe cognitive and motor deficits. Using human genetic data and mouse models, we will analyse how disrupting these genes affects brain development, and changes the overall structure and wiring of the cerebral cortex as well as behaviour.

Summary
Cerebral Palsy (CP) is the commonest neurological disability in children, affecting 1 in every 500 children. This research will investigate genetic causes of CP by testing families with and without CP for a range of genetic alterations that change fetal protection to inflammation with resultant brain damage and CP. Research in to the causes of CP will allow prevention strategies to be developed, to ultimately reduce social and financial costs of CP for the patient, their family and the community ....Cerebral Palsy (CP) is the commonest neurological disability in children, affecting 1 in every 500 children.

Summary
The two sides of the brain communicate via a large fibre tract called the corpus callosum. This proposal investigates how the corpus callosum is formed during embryonic and postnatal development. Specifically, we investigate how the axons that make up the corpus callosum are able to locate their precise target in the contralateral hemisphere so that the brain circuit they form will be functional. We have developed a new mouse model to discover the fundamental mechanisms regulating how the brain ....The two sides of the brain communicate via a large fibre tract called the corpus callosum.

Guidance Mechanisms Regulating The Development Of Axonal Projections From The Cingulate Cortex.

Summary
The corpus callosum is the largest fibre tract in the brain and connects neurons in the left and right cerebral hemispheres. A subpopulation of callosal axons arise from neurons in the cingulate cortex and are the first to cross the midline. Defects in activation or wiring of the cingulate cortex are strongly implicated in acute pain, schizophrenia and bipolar disorder. This proposal investigates how the commissural projections of the cingulate cortex become wired up during development.

Summary
In the developing brain, the two cerebral hemispheres undergo interhemispheric fusion to allow commissural fibres to cross the midline. Lack of interhemispheric fusion results in agenesis of the corpus callosum and may manifest as an interhemispheric cyst in acallosal patients. This project will investigate the cellular and molecular mechanisms that regulate interhemispheric fusion, including removal of the leptomeninges, astroglial differentiation and the formation of adherens junctions at the ....In the developing brain, the two cerebral hemispheres undergo interhemispheric fusion to allow commissural fibres to cross the midline.

Summary
The integration of information between the brain hemispheres occurs via a large bundle of connecting nerve fibres called the corpus callosum. People with a genetic mutation in DCC display mirror movement disorder and some have a severe brain defect where the corpus callosum fails to form, but at present we don’t understand the function of this gene. In this study we will investigate how DCC functions in early brain development to regulate corpus callosum formation and mirror movement disorder.
