Multimodal retinal imaging provides "insight" into cerebrovascular ageing. This project aims to develop a multi-modal imaging technology platform to simultaneously measure amyloid beta and its neurovascular sequelae to identify novel early biomarkers of ageing in the eye and brain. The growing ageing population is an increasing socioeconomic burden. The central nervous system is particularly susceptible to ageing, which is difficult to measure at its onset. Critically, as the eye is an easily accessible extension of the cortex, retinal imaging may be a non-invasive surrogate to assess ageing changes in the brain. Anticipated outcomes are a sensitive detector of neural ageing, improved preventative measures, reducing the socioeconomic burden of ageing, and improved quality of life.Read moreRead less
The role of LIM Kinase 1 in neurons. The aim of this project is to study LIM domain kinase 1 in neuronal function, using cell and mouse models. Unrestricted brain function is essential to one’s wellbeing and the ability to perform normally. Critically contributing to the function of neurons is a cytoskeleton which maintains morphology and function. However, molecular mechanisms underlying cytoskeletal dynamics are poorly understood. LIM domain kinase 1, a key regulator of the actin cytoskeleton ....The role of LIM Kinase 1 in neurons.

Critically contributing to the function of neurons is a cytoskeleton which maintains morphology and function. However, molecular mechanisms underlying cytoskeletal dynamics are poorly understood. LIM domain kinase 1, a key regulator of the actin cytoskeleton decreased with age and its loss associated with deficits in memory and neuronal morphology. This project could reveal fundamental processes regulating and maintaining brain function.Read moreRead less
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.
Physiology of tau protein: a novel role in scaffolding and intracellular distribution. Understanding brain function remains a challenge. This project will study the normal role of the Alzheimer's disease-related protein tau in brain function during ageing. This will significantly enhance current understanding of brain function.

Summary
Novel postsynaptic functions of the microtubule-associated protein tau. The protein tau is present in abnormal deposits in brains of individuals with dementia. The main aim of this project is to unravel and understand in detail new roles of tau in neurons and thus shed new light into normal brain function. Understanding these new functions of tau will aid in identifying new ways to treat these debilitating diseases.
Improving neuronal cell function with cell permeable copper complexes. Metal-based drugs offer an exciting new approach to treatment of neurodegeneration. However, little is known about how cells metabolise these drugs and this information is critical for further drug development. This project will determine how metal-based drugs are metabolised by neuronal cells and how this may result in therapeutic benefit.
Cellular mechanisms that protect against copper-bound beta-amyloid. This project will investigate some of the brain’s own mechanisms for protecting itself against Alzheimer’s disease. Understanding these mechanisms will be important for developing future therapeutic strategies for treating Alzheimer’s disease.
Prevention of age-related learning and memory dysfunction with novel compounds. This project will illuminate the fundamental brain changes that lead to age-related cognitive decline and to then test the validity of this as a novel therapeutic target. The expected outcome of this work will be a unique approach to the treatment of cognitive decline that will fill a significant unmet need within the community.
The Neural Bases of Decision-Making. The smooth integration of cognitive and emotional processes is necessary for everyday decisions. Dysfunction in this integrative capacity accompanies dementia, neurodegenerative conditions and major psychiatric disorders. This project seeks to understand the neural bases of this integration in normal decision-making using cutting edge behavioural, cellular, molecular and genetic tools to map the neural system, circuit and cellular processes controlling the se ....The Neural Bases of Decision-Making. The smooth integration of cognitive and emotional processes is necessary for everyday decisions. Dysfunction in this integrative capacity accompanies dementia, neurodegenerative conditions and major psychiatric disorders. This project seeks to understand the neural bases of this integration in normal decision-making using cutting edge behavioural, cellular, molecular and genetic tools to map the neural system, circuit and cellular processes controlling the selection, evaluation and choice of goal-directed actions. Such actions can, with continued practice, transition into relatively inflexible habits. Thus, this project aims to investigate the neural processes that mediate this transition and how actions and habits interact in normal decision-making.Read moreRead less
The neural bases of decision-making. The aim of this project is to understand the brain circuits controlling voluntary or goal-directed actions and particularly the memory processes that contribute to such actions. Goal-directed action is a fundamental capacity necessary for normal decision-making that is significantly attenuated by normal aging. This project aims to establish the neural circuits engaged in encoding new goal-directed actions, how this encoding is accomplished without interfering ....The neural bases of decision-making. The aim of this project is to understand the brain circuits controlling voluntary or goal-directed actions and particularly the memory processes that contribute to such actions. Goal-directed action is a fundamental capacity necessary for normal decision-making that is significantly attenuated by normal aging. This project aims to establish the neural circuits engaged in encoding new goal-directed actions, how this encoding is accomplished without interfering with pre-existing memories and how these memories are later retrieved to guide planning and performance. Understanding the determinants of such actions will enable the development of novel ways to treat ageing-related deficits in decision-making with significant economic benefits. Read moreRead less
