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
Identifying the basis for perceptual stability and perceptual omission during saccadic eye movements. The ability to explore the world via eye movements is an important feature of visual capabilities. This project will establish how the brain maintains the perception of a stable and stationary world despite the several eye movements made each second. This knowledge will fill a conspicuous gap in the understanding of the human visual system.
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
INVESTIGATION OF A BRAIN RHYTHM. Elucidation of brain function remains a frontier for human discovery. To date, research has largely focussed on brain connectivity with major advances in knowledge of input/output function of brain regions. Yet, there remains little understanding of higher order processes that underlie functions such as mood states and consciousness. Investigation of brain rhythms represent a step to unravelling such processes, as rhythms both act as autonomous clocks and generat ....INVESTIGATION OF A BRAIN RHYTHM. Elucidation of brain function remains a frontier for human discovery. To date, research has largely focussed on brain connectivity with major advances in knowledge of input/output function of brain regions. Yet, there remains little understanding of higher order processes that underlie functions such as mood states and consciousness. Investigation of brain rhythms represent a step to unravelling such processes, as rhythms both act as autonomous clocks and generate synchronised neuronal activity. This project aims to investigate mechanisms underlying a specific class of brain rhythm implicated in control of mood states. Positive outcomes from this basic research may lead to better drug therapies for controlling specific mental disorders.Read moreRead less

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.
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.
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.

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.

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
