Summary
It has been proposed that engagement in purposeful complex mental stimulation provides protection against dementia. The Tasmanian Healthy Brain Project (THBP) is a unique, large-scale prospective trial that examines whether university-level study in older adult population reduces ageing-related cognitive decline and risk of dementia. This project will also examine how an individual’s genetic profile may influence the potential benefits of complex mental stimulation as well as risk of dementia.
Development of an amoebic gill disease vaccine to protect Atlantic salmon. This project aims to identify candidate vaccine antigens and produce an experimental vaccine against amoebic gill disease (AGD) that will benefit the Tasmanian and international Atlantic salmon aquaculture industries. AGD is the most significant health problem affecting Atlantic salmon aquaculture in Tasmania. In the last decade, AGD has become a legitimate health threat to the multibillion dollar global Atlantic salmon i ....Development of an amoebic gill disease vaccine to protect Atlantic salmon. This project aims to identify candidate vaccine antigens and produce an experimental vaccine against amoebic gill disease (AGD) that will benefit the Tasmanian and international Atlantic salmon aquaculture industries. AGD is the most significant health problem affecting Atlantic salmon aquaculture in Tasmania. In the last decade, AGD has become a legitimate health threat to the multibillion dollar global Atlantic salmon industry. A solution is needed before AGD fully establishes itself in the largest Atlantic salmon producing nations. The expected outcome of this project is the development of a commercial vaccine that should significantly benefit the Australian and international aquaculture industries. Read moreRead less

Developing a Unified Theory of Episodic Memory. This project aims to develop a model of episodic memory and to apply the model to both adult and child development data. Unlike current approaches, the model is expected to address multiple memory tasks including item recognition, associative recognition, source recognition and cued recall, and also aims to address reaction time data, allowing different sources of interference causing forgetting in adults to be identified. By addressing both encodi ....Developing a Unified Theory of Episodic Memory. This project aims to develop a model of episodic memory and to apply the model to both adult and child development data. Unlike current approaches, the model is expected to address multiple memory tasks including item recognition, associative recognition, source recognition and cued recall, and also aims to address reaction time data, allowing different sources of interference causing forgetting in adults to be identified. By addressing both encoding and retrieval processes, the model can assess how changes in different sources of interference modulate performance through the trajectory of early development. Hierarchical Bayesian estimation aims to enable a simultaneous account of multiple tasks and support future deployment in applied contexts.Read moreRead less
Intracortical inhibition evaluated by paired-pulse TMS during choice and simple reaction time tasks. The research will investigate the neurophysiological processes responsible for the selection and initiation of movement in response to an external stimulus. Slowness in the initiation and execution of movement is a common feature of 'neurological aging', neurodegenerative disease, and brain injury. Understanding the brain mechanisms involved in response selection and movement initiation will pro ....Intracortical inhibition evaluated by paired-pulse TMS during choice and simple reaction time tasks. The research will investigate the neurophysiological processes responsible for the selection and initiation of movement in response to an external stimulus. Slowness in the initiation and execution of movement is a common feature of 'neurological aging', neurodegenerative disease, and brain injury. Understanding the brain mechanisms involved in response selection and movement initiation will provide information for the development of specific intervention techniques to improve motor function in these groups.Read moreRead less
The role of turgor in hyphal extension of the Ascomycete Neurospora crassa. Cellular expansion is an absolute necessity during the growth and development of plants and fungi. This process relies heavily upon the accumulation of inorganic ions. Osmotically driven water influx then creates the hydrostatic pressure that underlies the increase in cell volume. Cellular expansion is normally asymmetric and localised in one small region, such as hyphal tip. How does the cell maintain the turgor that dr ....The role of turgor in hyphal extension of the Ascomycete Neurospora crassa. Cellular expansion is an absolute necessity during the growth and development of plants and fungi. This process relies heavily upon the accumulation of inorganic ions. Osmotically driven water influx then creates the hydrostatic pressure that underlies the increase in cell volume. Cellular expansion is normally asymmetric and localised in one small region, such as hyphal tip. How does the cell maintain the turgor that drives expansion? How is expansion controlled spatially? These questions will be addressed in this project by comprehensive study of ion transport processes in a model organism, Neurospora crassa, using osmotic sensitive and transport mutants.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
Neural correlates of performance trade-offs and interference in dual-task performance. Our daily lives are characterised by our ability to produce and sustain a wide range of different movement patterns and to deliberately change patterns as the situation demands. In this project we seek to understand the relationship between brain processes, attentional demands, and the control and learning of coordinated behaviour. A further aim will be to examine how this relationship may be altered as a re ....Neural correlates of performance trade-offs and interference in dual-task performance. Our daily lives are characterised by our ability to produce and sustain a wide range of different movement patterns and to deliberately change patterns as the situation demands. In this project we seek to understand the relationship between brain processes, attentional demands, and the control and learning of coordinated behaviour. A further aim will be to examine how this relationship may be altered as a result of aging, degenerative disease, or brain damage. This research will provide a foundation upon which rehabilitation strategies can be developed for the movement impaired.Read moreRead less
