A longitudinal study of neuropsychological and neuromotor effects of low level manganese exposure. This study will investigate the neuropsychological and neuromotor effects of low level exposure to mangenese particulate. Previous studies have indicated symptomology of high level exposure, but there is contention in the literature regarding the effects of low levels of exposure. Our aim is to refine measures of cumulative exposure and develop a more comprehensive and senstitive testing protocol t ....A longitudinal study of neuropsychological and neuromotor effects of low level manganese exposure. This study will investigate the neuropsychological and neuromotor effects of low level exposure to mangenese particulate. Previous studies have indicated symptomology of high level exposure, but there is contention in the literature regarding the effects of low levels of exposure. Our aim is to refine measures of cumulative exposure and develop a more comprehensive and senstitive testing protocol than has been reported thus far. These measures and protocols will be incorporated into a longitudinal design, which has not been conducted in research studies to date. In addition, a database of exposure variables will be developed to facilitate long-term, accurate research into the effects of the low levels of exposure.Read moreRead less
Understanding biological pathways underlying social behaviour in humans. This project aims to show for the first time how oxytocin interacts with neural social and reward pathways to guide social behaviour. Oxytocin is a natural neuropeptide and hormone that has a critical role in the regulation of social behaviour across mammalian species. In animals, direct evidence demonstrates how endogenous and exogenous oxytocin interacts with social and reward neural pathways to alter social behaviour, in ....Understanding biological pathways underlying social behaviour in humans. This project aims to show for the first time how oxytocin interacts with neural social and reward pathways to guide social behaviour. Oxytocin is a natural neuropeptide and hormone that has a critical role in the regulation of social behaviour across mammalian species. In animals, direct evidence demonstrates how endogenous and exogenous oxytocin interacts with social and reward neural pathways to alter social behaviour, including social recognition, relationship formation, and long-term bonds. The project intends to use radio-labelling techniques in combination with positron emission tomography to track oxytocin and show what regions of the brain oxytocin impacts to then influence social cognition and behaviour in humans.Read moreRead less
Evaluation of a multidimensional cognitive enhancement training program for healthy older adults. The percentage of the Australian population aged 65 years and over is projected to increase considerably over the next 50 years. The increased number of older Australians will have a major economic cost in terms of income support and the provision of health services. It is of high socioeconomic importance, therefore, to promote functional independence in this group. The implementation of cognitive e ....Evaluation of a multidimensional cognitive enhancement training program for healthy older adults. The percentage of the Australian population aged 65 years and over is projected to increase considerably over the next 50 years. The increased number of older Australians will have a major economic cost in terms of income support and the provision of health services. It is of high socioeconomic importance, therefore, to promote functional independence in this group. The implementation of cognitive enhancement programs that may slow age-related cognitive decline and, thereby, maximise quality of life and independence for a long as possible will have significant national benefit.Read moreRead less
Attentional and conditioning mechanisms that mediate overcoming anxiety. Anxiety is a common emotion for most Australians that can cause substantial costs for individuals and society. This project uses dominant psychological models to identify critical mechanisms that are believed to predict capacity for, and change in, anxiety. Outcomes substantially advance knowledge about how humans overcome anxiety.
Gene-brain pathways in emotional brain stability and instability. Emotional instability is a defining trait of major mental illnesses. The ability to identify individuals susceptible to emotional instability will be important in limiting the burden of disease from these illnesses. Mental conditions cost the Australian economy approximately $14.9 bill p/a, and depression will be the second leading contributor to burden of disease by 2020. The project will provide the first evidence for the combin ....Gene-brain pathways in emotional brain stability and instability. Emotional instability is a defining trait of major mental illnesses. The ability to identify individuals susceptible to emotional instability will be important in limiting the burden of disease from these illnesses. Mental conditions cost the Australian economy approximately $14.9 bill p/a, and depression will be the second leading contributor to burden of disease by 2020. The project will provide the first evidence for the combination of gene-brain-behaviour markers which best capture emotional instability versus resilience. This evidence base will be crucial to developing new tools and strategies for early intervention, and ultimately prevention, for these conditions of mental health.Read moreRead less
CogChip: development of a targeted genotyping chip for executive function. This project aims to use DNA sequencing technology to identify the genetics of executive function. Our capacities to focus on a task at hand, to filter distractions and to inhibit unwanted impulses, are collectively referred to as executive functions. Executive function varies on a continuum in the general population across the lifespan, with individual differences largely due to differences in underlying genetics. The pr ....CogChip: development of a targeted genotyping chip for executive function. This project aims to use DNA sequencing technology to identify the genetics of executive function. Our capacities to focus on a task at hand, to filter distractions and to inhibit unwanted impulses, are collectively referred to as executive functions. Executive function varies on a continuum in the general population across the lifespan, with individual differences largely due to differences in underlying genetics. The project proposes to leverage this knowledge to develop a customised genotyping chip, which may find application for prediction of individual differences in executive ability across multiple settings including education and industry. Expected outcomes for the project will include breakthrough insights into the biology of cognition, and a genetic read-out of individual differences in executive ability, which could have broad application including the potential to facilitate the targeting of cognitive, educational or workplace training for those most at risk of adverse outcomes.Read moreRead less
An investigation of memory functioning of the prefrontal cortex. This project aims to investigate the role of the prefrontal cortex in human memory. While the medial temporal lobe has long been recognised as imperative for basic memory processes, the prefrontal cortex has only recently been recognised to mediate higher-level strategic memory processes. This project will clarify the memory functions of the dorsolateral, orbitofrontal, and medial prefrontal lobes by studying performance of individ ....An investigation of memory functioning of the prefrontal cortex. This project aims to investigate the role of the prefrontal cortex in human memory. While the medial temporal lobe has long been recognised as imperative for basic memory processes, the prefrontal cortex has only recently been recognised to mediate higher-level strategic memory processes. This project will clarify the memory functions of the dorsolateral, orbitofrontal, and medial prefrontal lobes by studying performance of individuals with damage in these areas using memory tests and tasks. Our findings will enhance understanding and theorising of the neural basis of memory and have implications for management and rehabilitation of memory impairments in brain injured individuals.Read moreRead less

Next generation smart lighting to improve sleep and alertness. Light has a powerful influence on our sleep and alertness. The manipulation of the amount of blue in a light source and the visual brightness of a light source are key factors, but there has been no systematic study that can guide manufacturers in the design of the ideal light source for promoting either sleep or alertness. This study will systematically examine the impact of the amount of blue light in a light source and the visual ....Next generation smart lighting to improve sleep and alertness. Light has a powerful influence on our sleep and alertness. The manipulation of the amount of blue in a light source and the visual brightness of a light source are key factors, but there has been no systematic study that can guide manufacturers in the design of the ideal light source for promoting either sleep or alertness. This study will systematically examine the impact of the amount of blue light in a light source and the visual brightness, creating a wide range of combinations that can be used to model the optimal light specifications for sleep and alertness, while maintaining visual acuity and colour discrimination. This will be the evidence base needed by the lighting industry to create the next generation of smart lighting.Read moreRead less
Environmental impact on neuroendocrine and neurobiological mechanisms: treatment strategies and mimetics for maintaining good health.

The current societal climate of industrialized countries such as Australia has shifted considerable over recent decades and is now one which is highly conducive to overfeeding and reduced physical activity. As a result, the incidence of obesity has risen markedly along with an associated increase in obesity-related chronic diseases such as cardiovascular disease, stroke, obstructive pulmonary disease, type II diabetes, and many types of cancers. Less is known about the psychological and behavioural sequelae of this overfeeding. Calorie restriction mimetics may not only act as a preventative intervention to help reduce the incidence and severity of these major health problems, but also impact on social behaviour.Read moreRead less
