Development And Plasticity Of The Visual Cortex: An Anatomical And Functional Study

Funding Amount
$420,872.00
Summary
Much of the human brain is devoted to vision, which requires the integrated activity of many interconnected areas of the cerebral cortex. Damage to these areas is a relatively common complication of preterm delivery and- or perinatal conditions including trauma and infection. The aim of this project is to investigate the way in which the multiple visual areas of the brain develop and become 'wired' together, and determine how the brain can successfully compensate for damage to these areas.
Regulation Of Neural Progenitor Cell Self-renewal By The RNA-binding Protein ZFP36L1 During Development And Disease

Summary
The timely differentiation of neural stem cells is critical during development, and the unrestrained proliferation of neural stem cells in the adult can lead to deadly brain cancers such as glioma. At present our understanding of the key molecules that regulate neural stem cell behaviour during these processes remains limited. In this proposal we will investigate the molecular determinants underpinning neural stem cell biology, both within the developing brain, and within glioma.
Identifying An Autism Gene Network Governing Stem Cell Division, Neurogenesis And Cortical Malformation

Summary
Failure to produce neural stem cells and new neurons in the embryonic cortex results in cortical malformations and autism, and thus has profound consequences for the individual's survival and quality of life. Here we explore how a unique network of autism proteins maintains stem cell activity and neuronal production, thereby ensuring the fidelity of cortical development.
Determining The Genetic Control Of Corpus Callosum Development

Funding Amount
$625,800.00
Summary
Disorders of early brain development are significant causes of illness and disability in children, who present with a number of clinical problems including delayed development, seizures, weakness and learning difficulties. The cause of these conditions remains poorly understood, however it is emerging that genes play a key role. This project will identify and characterise novel genes associated with abnormal brain development and identify new potential targets for treatment.
Nuclear Factor One Genes Regulate Multiple Aspects Of Cerebral Cortex Development

Summary
To function, the brain must be formed correctly during embryonic development. We are investigating the embryonic development of the cerebral cortex, an area involved in high-order cognitive processing. Recently, we discovered that an important group of genes regulates cortical development, making it possible to study the underlying molecular mechanisms. The results will impact the prognosis and treatment of developmental brain disorders.

Damage to these areas is a relatively common complication of preterm delivery and- or perinatal conditions including trauma and infection. The severity of both the short- and long-term effects of these lesions appears to be related to the time of the damage. The aim of this project is to investigate the way in which the multiple visual areas of the brain develop and become 'wired' together in the period following birth. We will also determine if there are mechanisms which allow alternate routes to be found for processing visual information while the brain is still establishing connections between its multiple areas. This will allow us to understand the anatomical and physiological bases of the deficits caused by early damage to the visual areas of the brain, and perhaps point to strategies that will lead to improved recovery of visual function.Read moreRead less
Novel MRI Approaches To Map Focal Cortical Dysplasia In Focal Epilepsy

Summary
Focal cortical dysplasia (FCD) is a common cause of focal epilepsy that is resistant to medication. When it can be identified clearly, surgical removal can cure the epilepsy but better methods of detecting and mapping FCD are required because standard imaging techniques are negative in 30% of patients. In this project, we plan to develop new MRI methods to diagnose FCD, thereby creating a new MRI-based diagnostic tool for patients with focal epilepsy who are potential surgical candidates.
