Establishment of a South Australian rTMS Facility. It is proposed to establish a South Australian Facility for rapid rate transcranial magnetic stimulation (TMS) which will be the only one in Australia. This Facility will provide enormous opportunities for collaborative cutting edge investigations into the role of the human cortical areas in a diverse range of tasks.

It is proposed to establish a South Australian Facility for rapid rate transcranial magnetic stimulation (TMS) which will be the only one in Australia. This Facility will provide enormous opportunities for collaborative cutting edge investigations into the role of the human cortical areas in a diverse range of tasks. For example, projects have been identified projects employing rTMS to study sensorimotor cortical plasticity, facilitate functional recovery following stroke and investigate the mechanisms of savant behaviour. Provision of this Facility will provide further support for this productive and internationally renowned group of scientists to develop their research programs.Read moreRead less
Pathophysiological Decision-making In Children With Obsessive-compulsive Disorder And Tic Disorders: Action-selection And Imaging Correlates

Funding Amount
$124,676.00
Summary
Why is it that a person with obsessive-compulsive disorder (OCD) has trouble deciding whether or not to wash their hands? We scanned the brains of teenagers with OCD while they made decisions and found that they had difficulty using cues in their environment to direct choices. This may be an early vulnerability for the development of the disorder that could guide prevention. We plan to check if that difficulty is present in younger children with OCD and their family members.
Long-term Outcomes After Paediatric Traumatic Brain Injury

Funding Amount
$431,000.00
Summary
Traumatic brain injuries during early childhood often result in long-lasting issues including social behaviour problems and post-traumatic epilepsy. Using a unique model of brain injury in young mice, my research aims to identify the biology underlying the changes that cause these issues, and evaluate novel approaches to improve long-term outcomes after brain injury.
Social Dysfunction After Paediatric Brain Injury In Mice

Summary
Brain injuries during early childhood may evolve over time, with long-lasting consequences on one's ability to socially interact with others. In this study, we hypothesise that social behaviour problems result from damage to white matter tracts in the immature brain. By using a unique model of brain injury in young mice, plus advanced imaging and behavioural methods, we will provide new understanding about the cause of social problems, and evaluate a rehabilitation approach to improve outcomes.
Position perception, attention, object motion, and action. The research will achieve a deeper understanding of the neural processing of the visual perception of position, and of the associated behavioural limits. This will provide a foundation for the development of a range of technologies to assist disabled and elderly people. The results will help reveal the link between the perception of moving objects and the capacity for visually guided movement. This link will benefit areas such as enginee ....Position perception, attention, object motion, and action. The research will achieve a deeper understanding of the neural processing of the visual perception of position, and of the associated behavioural limits. This will provide a foundation for the development of a range of technologies to assist disabled and elderly people. The results will help reveal the link between the perception of moving objects and the capacity for visually guided movement. This link will benefit areas such as engineering of vehicles and road systems, and the design of telepresence systems. The first applications are likely to be in the rehabilitation of brain injury and the decline of mental function with age.Read moreRead less
Characterisation of monoaminergic transmission in Central Amygdala. This project will identify the distribution and function of dopamine, serotonin and noradrenalin receptors on the various cell types and their inputs, in the medial, lateral and capsular divisions of Central Amygdala (CeA). We will test for tonic endogenous activation of monoaminergic receptors and synaptic release from electrically stimulated fibers terminating in CeA. Using paired recordings and calcium imaging, we will invest ....Characterisation of monoaminergic transmission in Central Amygdala. This project will identify the distribution and function of dopamine, serotonin and noradrenalin receptors on the various cell types and their inputs, in the medial, lateral and capsular divisions of Central Amygdala (CeA). We will test for tonic endogenous activation of monoaminergic receptors and synaptic release from electrically stimulated fibers terminating in CeA. Using paired recordings and calcium imaging, we will investigate intracellular mechanisms underlying monoamine receptor mediated effects. These findings when correlated with published behavioural studies will provide greater understanding of the role of the divisions of CeA and the inputs they receive, in the function of the amygdala.Read moreRead less
The psychobiology of forgetting: Opioid receptors and inhibitory constraints on storage of long-term memory. This project has four main national benefits. First, it addresses a fundamental scientific and practical issue: the psychobiology of forgetting. Second, it will provide important insights into variations in memory functioning across the lifespan. A significant challenge facing Australia is understanding, and where possible alleviating, the decline in mental function that occurs with age. ....The psychobiology of forgetting: Opioid receptors and inhibitory constraints on storage of long-term memory. This project has four main national benefits. First, it addresses a fundamental scientific and practical issue: the psychobiology of forgetting. Second, it will provide important insights into variations in memory functioning across the lifespan. A significant challenge facing Australia is understanding, and where possible alleviating, the decline in mental function that occurs with age. This project may help identify targets to alleviate age-related impairments in memory. Third, this project will contribute to Australia's international reputation in behavioural neuroscience. Fourth, this project will provide outstanding training opportunities for Australian undergraduate and postgraduate research students in behavioural neuroscience.Read moreRead less

Summary
Our research aims to describe and understand newly identified nerve pathways or 'networks' in brain that control physiological homeostasis or balance and complex behaviours, including levels of arousal and motivation, sleep/wake patterns, learning and memory, and emotions such as fear and anxiety
Sensory Coding Mechanisms in Rat Somatosensory System; A Combined Behavioural and Electrophysiological Approach. This inter-disciplinary project spans behavioural sciences, neurophysiology and computational neuroscience. It investigates fundamental questions such as how different aspects of stimuli are presented in sensory areas of the brain and how the animal interprets the neuronal activity in such areas to generate the relevant behaviour.

This inter-disciplinary project spans behavioural sciences, neurophysiology and computational neuroscience. It investigates fundamental questions such as how different aspects of stimuli are presented in sensory areas of the brain and how the animal interprets the neuronal activity in such areas to generate the relevant behaviour. A major problem with making prosthetic sensory devices is the way by which these devices can communicate with the brain. Research into the coding of different features of simple stimuli will provide basic knowledge which can be implemented in prosthetic sensory devices. Read moreRead less
