Neurological cell replacement therapies: improving outcomes by matching developmental profiles of transplanted cells with the damaged brain area. Stem cell transplantation offers a way to replace nerve cells lost due to acute CNS injury or chronic degenerative conditions such as Parkinson's Disease. However, to date, results have been disappointing because of poor differentiation, survival and integration of stem cells confounded by ethical issues associated with the use of embryos as the source ....Neurological cell replacement therapies: improving outcomes by matching developmental profiles of transplanted cells with the damaged brain area. Stem cell transplantation offers a way to replace nerve cells lost due to acute CNS injury or chronic degenerative conditions such as Parkinson's Disease. However, to date, results have been disappointing because of poor differentiation, survival and integration of stem cells confounded by ethical issues associated with the use of embryos as the source of stem cells. The experiments conducted in this study will provide strategies to improve the efficacy of stem cell transplantation into the damaged CNS as well as developing the use of autologous bone marrow stem cells for repair. Outcomes will be improved transplant methodologies and expertise for the bio-technology industry. Read moreRead less
Listen and learn - statistical learning and the adapting auditory brain. This project aims to explore the link between rapid neural adaptation - a form of learning referred to as statistical learning - and human listening performance in noisy environments. The project aims to generate a new understanding of mechanisms that contribute to listeners' abilities to understand speech in noise, and to complex communication disorders such as dyslexia. Expected outcomes will include increased capacity to ....Listen and learn - statistical learning and the adapting auditory brain. This project aims to explore the link between rapid neural adaptation - a form of learning referred to as statistical learning - and human listening performance in noisy environments. The project aims to generate a new understanding of mechanisms that contribute to listeners' abilities to understand speech in noise, and to complex communication disorders such as dyslexia. Expected outcomes will include increased capacity to investigate a broad range of cognitive and communication functions. Benefits will include potential technologies and algorithms to assist listening (in devices such as hearing aids), language development and reading.Read moreRead less
Broad spectrum nanomedicine for Meningitis treatment. Brain inflammatory diseases are among the top ten infectious causes of death. The project aims to provide Australian doctors with a superior alternative of treating infections that do not respond to conventional antibiotics. The nanomedicine developed will reduce the burden of hospital and boost Australia economy in the biomedical sector.
Using magnetic nanotechnology to aid recovery from neurotrauma. Nanotechnology is an exciting new field that holds great promise to solve challenging health issues including neurotrauma associated with brain and spinal cord injury.

Nanotechnology is an exciting new field that holds great promise to solve challenging health issues including neurotrauma associated with brain and spinal cord injury. Current methods to deliver drugs and stimulate tissue repair after neurotrauma do not work effectively and new approaches are urgently need. The recently established research team brings together expertise in nanotechnology and neuroscience to develop new, safe ways to deliver drugs and stimulate tissue repair after neurotrauma, and provide quality research training. Specifically designed nanomaterials will deliver drugs slowly over time and act as scaffolds to stop cells dying and stimulate them to restore broken connections and work again. Read moreRead less
The critical role of kisspeptin/neurokinin/dynorphin (KNDy) neurons in gonadotropin releasing hormone (GnRH) release. The brain controls fertility through the secretion of its primary stimulatory factor, gonadotropin releasing hormone (GnRH). Brain cells producing three key peptide hormones, kisspeptin, neurokin B and dynorphin (termed KNDy cells) are vital for the control of GnRH. This project will detail the role of KNDy cells in puberty and reproduction.
Targeted enzymatic treatment of the injured central nervous system using innovative nanotechnology. Nanotechnology and other frontier areas in science have exciting potential to solve major challenges of the 21st century, including health.

Nanotechnology and other frontier areas in science have exciting potential to solve major challenges of the 21st century, including health. The proposed research provides the real possibility of discovering ways to alleviate the many complex problems associated with neurotrauma following, for example, brain and spinal cord injury. Current delivery of therapeutics do not work effectively and new approaches are urgently needed. The recently established powerful multidisciplinary research team combines expertise in nanotechnology, glycobiology and neuroscience to develop novel, safe ways to deliver therapeutic enzymes over biological time-courses. We aim to make broken connections work again, while providing quality research training.Read moreRead less
Subcellular recruitment of a RhoA ubiquitination complex by Rnd proteins. This study addresses a novel molecular mechanism through which members of the Rnd family of GTP-binding proteins regulate the morphology and migration of immature nerve cells of the developing nervous system. This study has broad implications for the understanding of cell migration during embryo development, as well as in health and disease.
Atypical cognition in autism: preference for nonverbal coding and impaired connectivity? This project will investigate whether individuals with autism prefer to think 'in pictures' rather than use words, and whether their thinking shows evidence of limited connections across brain regions. Establishing either characteristic for autism would provide important direction in improving diagnosis and intervention for affected children.
Single and dual process models of recognition memory: Reconciliation of behavioural, electrophysiological, and neuroimaging data. Advanced brain scanning technologies are increasingly used to study human memory. As well as being important for our basic understanding of memory, they also tell us how memory is affected by normal development, ageing, disease, and injury. Unfortunately, because these technologies are so new, a gap has opened up between our psychological understanding of memory and t ....Single and dual process models of recognition memory: Reconciliation of behavioural, electrophysiological, and neuroimaging data. Advanced brain scanning technologies are increasingly used to study human memory. As well as being important for our basic understanding of memory, they also tell us how memory is affected by normal development, ageing, disease, and injury. Unfortunately, because these technologies are so new, a gap has opened up between our psychological understanding of memory and the physiological events measured by the scanning technologies. This has created a problem for how we should interpret the results that are found. The present project aims to close this gap by applying new research methodologies and theoretical insights based on our previous research.Read moreRead less
Modulating neuron activity with terahertz light. The increasing prevalence of high frequency electromagnetic radiation for military applications, communication and imaging has prompted interest in the effects of these frequencies in neuroscience. The primary aim of this project is to understand the interactions and effects of terahertz light (or T-rays) on neurons and brain tissue and will build on Australia's position as a leader in terahertz technology.

The increasing prevalence of high frequency electromagnetic radiation for military applications, communication and imaging has prompted interest in the effects of these frequencies in neuroscience. The primary aim of this project is to understand the interactions and effects of terahertz light (or T-rays) on neurons and brain tissue and will build on Australia's position as a leader in terahertz technology. This work will identify optimal parameters for neuronal modulation with one of the potential outcomes being the possibility of controlling neuron firing rates which has applications in neuroscience. It also has clinical implications in terms of the suppression of pain and other neurological disorders.Read moreRead less
