A multidimensional model of social cognitive ageing. This project aims to develop and test a model of how normal adult ageing affects the critical ability to perceive, interpret and process social information. By using an innovative approach that integrates laboratory-based assessments with measures of real-life social behaviour, this project expects to generate novel insights into how ageing affects a range of important social cognitive skills, as well as when and why any age-related difficulti ....A multidimensional model of social cognitive ageing. This project aims to develop and test a model of how normal adult ageing affects the critical ability to perceive, interpret and process social information. By using an innovative approach that integrates laboratory-based assessments with measures of real-life social behaviour, this project expects to generate novel insights into how ageing affects a range of important social cognitive skills, as well as when and why any age-related difficulties emerge. Expected outcomes include a better understanding of the factors that drive resilience and risk for social cognitive difficulties in late adulthood, with direct implications for promoting social engagement and preventing social detachment in Australia’s growing older adult community.Read moreRead less
Testing theoretical models of age and disease related changes to inform prevention. Pathological brain changes associated with future cognitive decline become detectable in the 40s or earlier. Yet little is known about what constitutes normal brain ageing in mid-life. Using a number of neuroimaging and epidemiological techniques this project will scrutinise brain and cognitive ageing in middle-age and their significance.
The role of P2X7 and P2X4 receptor mediated innate phagocytosis in pathogenesis and treatment of neurodegenerative diseases. This project will identify how inherited variation in two proteins of the brain can accelerate the removal of neurones and predispose to a range of neurodegenerative diseases. Knowledge of the biological basis of this finding will allow a search for new compounds which will slow and protect against this form of neurodegeneration.
Why remembering together is crucial as we age. This project will test whether remembering everyday information or important past events with a long-term partner compensates for, predicts and/or reduces the risk of memory and cognitive decline. The project will identify and then target for treatment the strategies that spouses use to help each other remember, especially as they age and memory starts to fail.
Harnessing non-invasive brain stimulation to improve language function in healthy and pathological ageing. This project will examine how the ability of the ageing brain to process language can be improved by non-invasive brain stimulation. The findings have the potential to reveal new ways to treat language impairments in ageing-associated brain injury and disease.
Understanding the contribution of neuroinflammation in acute and chronic neural injury. A major focus of this project will be investigating the involvement of neuroinflammation in neural cell damage. It will explore how neuroinflammation contributes to this damage in both acute and chronic neuropathologies.
The Genetic Analysis of Neurological Diseases. Multiple sclerosis and Parkinson's are debilitating neurodegenerative diseases, which affect 16,000 and 80,000 Australians, respectively. Between them, these diseases cost the community $7.8 billion per annum, and there is no cure. This proposal will study the genes that influence a person's predisposition to developing these diseases, and what makes some people have particular characteristics. It will provide novel insights into the diseases themse ....The Genetic Analysis of Neurological Diseases. Multiple sclerosis and Parkinson's are debilitating neurodegenerative diseases, which affect 16,000 and 80,000 Australians, respectively. Between them, these diseases cost the community $7.8 billion per annum, and there is no cure. This proposal will study the genes that influence a person's predisposition to developing these diseases, and what makes some people have particular characteristics. It will provide novel insights into the diseases themselves and information that could help in the development of new and more effective drugs, and biomarkers to assist in the prediction of prognosis. Such advances would decrease the economic impact of these diseases and improve quality of life for those affected.Read moreRead less
Enhancing our understanding of metallochemistry in neurobiology with modern electron paramagnetic resonance (EPR) spectroscopy. Many neurological diseases involve protein accumulation that appears causally linked to abnormal levels of metal ions in the brain. This project will use a special technique called electron paramagnetic resonance to uncover how these metals interact with specific proteins at the molecular level and how drug treatments can modify these interactions.
Combining evolutionary, physiological and molecular approaches to understand ageing and performance. How organisms grow, behave and perform is a result of environmentally triggered molecular, physiological and biochemical reactions. Little is known about how these different levels of organisation interact to create the infinite morphological and behavioural complexities seen in adults. This project aims to integrate the fields of developmental, physiological and evolutionary biology to elucidate ....Combining evolutionary, physiological and molecular approaches to understand ageing and performance. How organisms grow, behave and perform is a result of environmentally triggered molecular, physiological and biochemical reactions. Little is known about how these different levels of organisation interact to create the infinite morphological and behavioural complexities seen in adults. This project aims to integrate the fields of developmental, physiological and evolutionary biology to elucidate how the environment moderates cell and tissue development through gene expression. This will highlight how early developmental decisions affect lifetime energetic trade-offs and efficiency, and how underlying biology manifests into emergent phenomena such as performance, behaviour, ageing and lifespan.Read moreRead less
Investigating the neuroprotective actions of metallo-complexes. Metal-based drugs offer an exciting new approach to treatment of neurodegeneration. However, little is known about how cells metabolise these drugs: information that is critical for further drug development. This project will determine how metal-based drugs are metabolized by neuronal cells and how this may result in therapeutic benefit.
