The primary benefit of this project is to basic science and tertiary teaching globally. Visual processing and how it activates attention and operates to guide actions and cognitive behaviour is fundamental to our understanding of life and brain evolution. In particular this new knowledge will further understanding of many cognitive symptoms associated with neurodevelopmental disorders and in the future should lead to design of better educational technologies for such children. Similarly understanding of temporal sequencing of vision has commercial implications for design of bionic eyes and robotic vision processing.Read moreRead less
Mechanisms of fear learning and extinction in the mammalian brain. The brain is a remarkable machine that coordinates all aspects of our daily lives including the storage and retrieval of memories. Given that many age-related degenerative disorders are associated with marked changes in learning and memory it also has implications for Australia's National Research Priority 2 "Ageing well and ageing productively". This research aims to discover the basic mechanisms that underlie memory storage an ....Mechanisms of fear learning and extinction in the mammalian brain. The brain is a remarkable machine that coordinates all aspects of our daily lives including the storage and retrieval of memories. Given that many age-related degenerative disorders are associated with marked changes in learning and memory it also has implications for Australia's National Research Priority 2 "Ageing well and ageing productively". This research aims to discover the basic mechanisms that underlie memory storage and how these are modulated in an emotional context. It will also shed light on states such as anxiety, depression and post-traumatic stress, enhancing our ability to identify new therapeutic targets for such disorders.Read moreRead less
The role of the Supplementary Motor Area in time processing. The neural bases of timing mechanisms (0.1-100s range) are the subject of much debate. We hypothesise that the Supplementary Motor Area (SMA), a major cortical structure involving important dopaminergic pathways, subtends duration encoding, in the way depicted by the 'accumulator model'. Using transcranial magnetic stimulation (TMS) over the SMA, we will test healthy subjects in motor and perceptual timing tasks, compared to Parkinson' ....The role of the Supplementary Motor Area in time processing. The neural bases of timing mechanisms (0.1-100s range) are the subject of much debate. We hypothesise that the Supplementary Motor Area (SMA), a major cortical structure involving important dopaminergic pathways, subtends duration encoding, in the way depicted by the 'accumulator model'. Using transcranial magnetic stimulation (TMS) over the SMA, we will test healthy subjects in motor and perceptual timing tasks, compared to Parkinson's disease patients whose timing performance is impaired due to dopaminergic dysfunction. We expect TMS inhibitory effects to induce predictable performance trends, providing support for the accumulator model and the key role of the SMA in timing.Read moreRead less
Long-term memory systems and the human brain. Impairment of memory is a ubiquitous feature of human brain disease. A better understanding of memory processing in the brain is key to the development of better tests for the detection and monitoring of disease progression as well as the application of improved methods of rehabilitation for patients with acquired brain injury. This project will provide the catalyst for the development of a National Memory Disorders Research Centre that would be the ....Long-term memory systems and the human brain.

This project will provide the catalyst for the development of a National Memory Disorders Research Centre that would be the focus for multidisciplinary cognitive neuroscience research. The ultimate aim would be the translation of basic neuroscience into effective tools that will impact the health outcome of the ageing population.Read moreRead less
The role of the prefrontal cortex in responding to a changing world. This proposal will test a novel theory of frontal brain function that emphasises the contrasting role of two regions of the prefrontal cortex in dealing with the changing nature of the world. It will provide novel insights in the the psychology and neural underpinnings of the control of behaviour. This will add to our basic knowledge of brain function, feeding into our understanding of human mental disorders such as schizophren ....The role of the prefrontal cortex in responding to a changing world.

It will provide novel insights in the the psychology and neural underpinnings of the control of behaviour. This will add to our basic knowledge of brain function, feeding into our understanding of human mental disorders such as schizophrenia and dementia. It will also provide training in psychology and behavioural neuroscience for Honours and Doctoral students.Read moreRead less

Magnetic resonance in humans: Equipment for neuroscience studies. The structure, function and biochemistry of the human brain can now be assessed non-invasively using magnetic resonance (MR) techniques. A 3 Tesla MR facility with half its time available for research has recently been established at POWMRI.

The structure, function and biochemistry of the human brain can now be assessed non-invasively using magnetic resonance (MR) techniques. A 3 Tesla MR facility with half its time available for research has recently been established at POWMRI. This application seeks state-of-the-art equipment so that the facility can optimise its research potential and enhance its scientific output. Research is directed to understanding how the normal brain functions, how deficits in function develop, and how the function and structure of the brain change with age. This grant will help establish an internationally-competitive, broadly-based facility which is dedicated to understanding the human brain.Read moreRead less
Cellular Plasticity in the Brain: discovering molecular mechanisms controlling the production of neurons during brain development, function, ageing and disease. The program aims to understand the mechanisms regulating Brain Plasticity - this recently discovered property of the brain to respond to environmental stimuli, both physiological and pathological, by producing new functional neurons. Specifically, the program will discover how the brain's stem cells are stimulated to produce new neurons. ....Cellular Plasticity in the Brain: discovering molecular mechanisms controlling the production of neurons during brain development, function, ageing and disease. The program aims to understand the mechanisms regulating Brain Plasticity - this recently discovered property of the brain to respond to environmental stimuli, both physiological and pathological, by producing new functional neurons. Specifically, the program will discover how the brain's stem cells are stimulated to produce new neurons. This understanding will significantly expand our knowledge of how the brain develops, and how functions, like memory, are modulated by neuronal replacement. Discoveries will underpin the development of, in association with Australia's biotechnology sector, a new generation of therapeutics, which treat neurological diseases, like Stroke, by stimulating the production of functional neurons.Read moreRead less
An Australasian, Multi-centre, Randomized, Double-blind, Placebo-controlled Trial Of The Efficacy Of Fluoxetine In Improving Functional Recovery After Acute Stroke
Funder

Funding Amount
$2,306,367.00
Summary
Stroke is one of the top three causes of disability. Treatments that improve recovery after stroke are lacking. We reviewed the world literature and found a number of very small studies which, together, suggest that the antidepressant drug, fluoxetine, may improve the recovery in stroke patients. AFFINITY is a large trial in 1600 Australians and New Zealanders with stroke which aims to find out whether taking fluoxetine for 6 months after a stroke improves recovery compared to a placebo.
What Predicts The Progressive Phase Of Multiple Sclerosis

Summary
We have made major gains in our understanding of what causes MS. What has proven to be far more difficult is understanding the drivers of disability progression and conversion to progressive MS. The onset of progression heralds the accumulation of irreversible disability and is a critical time point to a person with MS. This grant aims to determine the lifestyle, environmental, genetic and epigenetic drivers of MS progression, using an internationally unique Australian MS longitudinal cohort.
