Normal And Abnormal Development Of Brain Wiring And Its Impact On Brain Function

Funding Amount
$763,845.00
Summary
My laboratory is striving to understand how the patterns of neuronal connections form in the developing brain and how these underpin the functions of the brain throughout life. We use high-field magnetic resonance imaging to measure brain wiring and we investigate the genetic and environmental mechanisms causing developmental brain disorders that result in intellectual disability, autism, epilepsy and some mental illnesses.
Targeting Tau Phosphorylation To Treat And Prevent Acquired Epilepsy, Neurodegeneration And Neuropsychiatric Disease Following A Brain Injury
Funder

Funding Amount
$524,820.00
Summary
This project will explore a new approach to the prevention and treatment of epilepsy and the associated mental health disorders following a brain injury. This involves inhibiting pathological forms of the Tau protein, which has been implicated in the development of epilepsy and neurodegeneration. The drug that will be tested in this study has already been demonstrated to be safe and well tolerated in humans, meaning that a positive result from these studies could be expediently translated into c ....This project will explore a new approach to the prevention and treatment of epilepsy and the associated mental health disorders following a brain injury.

A Systematic Evaluation Of The Neurosurgical Application Of Peri-operative And Intra-operative MR Tractography In Different Paediatric Disease States

Funding Amount
$130,910.00
Summary
My research investigates changes in brain nerve fibre tracts/white matter in paediatric disease states and changes related to surgery by using nerve fibre tract imaging before, during and after surgery. It will also generate an imaging atlas to help understand white matter pathway development. It then serves as normative comparison to better understand aberrations in diseased neural pathways. The outcome will aid understanding in brain development, recovery and plasticity, and helps improve whit ....My research investigates changes in brain nerve fibre tracts/white matter in paediatric disease states and changes related to surgery by using nerve fibre tract imaging before, during and after surgery.

Biomaterials For The Direct Reprograming Of Reactive Astrocytes Into Functional Neurons
Funder

Funding Amount
$630,500.00
Summary
We will employ peptide inspired hydrogel nanoscaffolds that can be injected into a brain lesion as a single injection to provide chemical and physical support for the surrounding cells. We will utilize various modifications to these materials to reprogram inflammatory cells into neurons, whilst also promoting the survival, maintenance and growth of existing neurons to encourage repair.
Dopamine Neuron Ontogeny: Convergent Neurobiological Pathway For Risk Factors Of Schizophrenia
Funder

Funding Amount
$337,214.00
Summary
Schizophrenia is associated with changes in dopamine (a signalling molecule in the brain). These changes are present prior to psychosis, suggesting they begin early in development. Our aims are to manipulate key factors in the development of brain dopamine systems to clarify their role in psychosis and schizophrenia. This work has the potential to identify early brain changes that lead to schizophrenia, which in turn may generate better diagnoses and outcomes for people with this disorder.
Seizures appear unpredictable and greatly affect the quality of all aspects of life for patients with epilepsy and their carers. New advances in complex systems theory suggest that transitions from normal brain activity to seizures are preceded by measurable changes in the brain’s responses to stimuli, known as critical slowing. Measurement of critical slowing will enable prediction of seizures, providing a warning system, and possibly an opportunity to deliver preventative therapies.
Stroke outcomes directly relate to brain tissue rescue. We have contributed to changes in clinical practice through many clinical trials of new protocols and therapeutic strategies. Our program will focus on brain salvage in the pre-hospital setting and the acute hospital environment. We will use novel approaches to enhance brain recovery and design new implementation strategies to maximise the benefits of these therapeutic advances.
Delayed Radial Glial Maturation Linked To NFI Deficiency As An Underlying Cause Of Cortical Defects In Humans And Mice
Funder
National Health and Medical Research Council
Funding Amount
$801,979.00
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.
How The Lateral Habenula Integrates Behavioral And Autonomic Functions: The VTA Dopamine Connection
Funder
National Health and Medical Research Council
Funding Amount
$819,904.00
Summary
When adverse events occur, the lateral habenula, an old brain nucleus, helps calculate the wisest corrective action by contributing to the “brake” that controls the brain’s dopamine reward system. Our research will show how the lateral habenula links corrective changes in behavior with coordinated changes in temperature. Understanding this link will greatly contribute to understanding the brain mechanisms that regulate our physiology during stressful situations and as part of mental illness.
Novel Strategies To Promote Myelin Repair In The Brain

Funding Amount
$597,865.00
Summary
Demyelinating diseases of the central nervous system such as multiple sclerosis have a lifelong impact and devastating impact on quality of life. We have identified that a growth factor, brain derived neurotrophic factor (BDNF), plays an important role in promoting myelination during development. We will investigate the potential of translating these findings into effective clinical treatment, by characterising the efficacy of BDNF in promoting CNS remyelination after a demyelinating insult.
