Orienting (OR) and Defensive Responses (DR) underlie important survival functions of attending to unexpected stimuli and avoiding harm.We will establish the first integrative profile of human OR/DR function, using simultaneous recording of brain activity and 'body' responsivity. Given sex and age variation in OR/DRs, both males and females spanning six decades will be studied. OR/DR abnormalities are associated with major disorders of attention and stress, which also vary with sex and age. We will examine relationships between OR/DR function and proneness to these disorders in healthy individuals. The results will provide a framework for developing prevention and intervention strategies.Read moreRead less

Attention-deficit/Hyperactivity Disorder (AD/HD) is the most common psychiatric disorder affecting children, resulting in substantial costs (both human and financial) to the child, their family and Australian society. The outcomes of this project will provide a better foundation for understanding dysfunctional brain mechanisms in AD/HD, which is expected to lead to better diagnosis, treatment, and community support. Ultimately this will contribute to a healthy start to life for these children. This project will also demonstrate how an integrated Australian approach can lead the research agenda in both basic neuroscience, at the interface of psychology and physiology, and its applications in health.Read moreRead less

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

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
Behaviour of large networks of neurons in a functioning organ: a realistic computer-based model of the enteric nervous system. The organisation of the gut nervous system is well understood, but how nerve cells cooperate to control gut movements and secretions are matters of conjecture. We will test these conjectures by simulating the behaviour of the gut nervous system using an anatomically and physiologically realistic computer model to predict the way the gut responds to specific stimuli and t ....Behaviour of large networks of neurons in a functioning organ: a realistic computer-based model of the enteric nervous system. The organisation of the gut nervous system is well understood, but how nerve cells cooperate to control gut movements and secretions are matters of conjecture. We will test these conjectures by simulating the behaviour of the gut nervous system using an anatomically and physiologically realistic computer model to predict the way the gut responds to specific stimuli and test these predictions using novel methods for recording gut movements and nervous activity. This will provide the first complete description of how a mammalian nervous system generates complex behaviours and will provide substantial pointers to how other nervous systems achieve similar tasks.Read moreRead less
