Adaptation and after effects in perception of tactile motion. This project investigates sensory properties of the skin covering the human hand, focusing on the ability to perceive how surfaces move across the palm when objects are handled or explored. This project aims to elucidate sensory information processing, leading to applications in diagnostics of neurological disorders and robotics.
Age and Gender Related Changes in Motor Control of the Upper Airway Muscle Genioglossus During Sleep. Obstructive Sleep Apnoea (OSA) is the repetitive obstruction of the airway during sleep. Obstructions occur because muscles of the upper airway fail to keep the airway open during inspiration. The disorder is associated with cardiovascular disease and cognitive and behavioural impairment. The prevalence of the disorder increases in older adults, contributing to age-related health and behavioural ....Age and Gender Related Changes in Motor Control of the Upper Airway Muscle Genioglossus During Sleep. Obstructive Sleep Apnoea (OSA) is the repetitive obstruction of the airway during sleep. Obstructions occur because muscles of the upper airway fail to keep the airway open during inspiration. The disorder is associated with cardiovascular disease and cognitive and behavioural impairment. The prevalence of the disorder increases in older adults, contributing to age-related health and behavioural problems. However, age-related changes differ in men and women. We believe the high prevalence of OSA in older adults is due to age and gender related changes in the activity of muscles in the upper airway. We will study the behaviour of the upper airway muscle genioglossus during sleep in young, middle-aged and older men and women.Read moreRead less

Summary
Cognitive Compensation in Ageing. Decline in cognitive control can have a devastating effect on an individual's capacity to live a high quality and safe independent life. It is an untested assumption that older adults can compensate for age-related changes in cognitive control function to perform at the same level as younger adults. This project aims to be the first to test this widely-held assumption and will examine changes in cognitive control and the emergence of compensation over the adult ....Cognitive Compensation in Ageing. Decline in cognitive control can have a devastating effect on an individual's capacity to live a high quality and safe independent life. It is an untested assumption that older adults can compensate for age-related changes in cognitive control function to perform at the same level as younger adults. This project aims to be the first to test this widely-held assumption and will examine changes in cognitive control and the emergence of compensation over the adult lifespan (20 to 90 years). The project aims to establish whether cognitive compensation is an effective mechanism to maintain cognitive control function into old age and will inform future strategies to help older individuals live more successful and productive independent lives for longer.Read moreRead less
Boosting brain plasticity and motor function in older adults. Ageing is associated with a pronounced decline in many motor, cognitive, and other brain functions, but the cause remains elusive. This project will examine the mechanisms that contribute to a decline in brain plasticity and motor function in the elderly. Using novel brain stimulation techniques, the project aims to develop an optimal approach to boost plasticity in the ageing brain and improve motor function. A better understanding o ....Boosting brain plasticity and motor function in older adults. Ageing is associated with a pronounced decline in many motor, cognitive, and other brain functions, but the cause remains elusive. This project will examine the mechanisms that contribute to a decline in brain plasticity and motor function in the elderly. Using novel brain stimulation techniques, the project aims to develop an optimal approach to boost plasticity in the ageing brain and improve motor function. A better understanding of changes in brain function and plasticity with advancing age is expected to help to optimise the design of preventative programs aimed at rejuvenating motor and cognitive function in the elderly.Read moreRead less
Brides and Grandmothers: Challenges for Older Filipinos in Australia. This project investigates the settlement, acculturation experiences, and psychological wellbeing of older Filipino women who arrived in Australia under different circumstances. Some have migrated to Australia as young brides to marry Australian citizens and some as grandmothers to be reunited with family members. Five hundred older Filipino women, and a group of 100 men living in rural and urban areas, will participate in the ....Brides and Grandmothers: Challenges for Older Filipinos in Australia. This project investigates the settlement, acculturation experiences, and psychological wellbeing of older Filipino women who arrived in Australia under different circumstances. Some have migrated to Australia as young brides to marry Australian citizens and some as grandmothers to be reunited with family members. Five hundred older Filipino women, and a group of 100 men living in rural and urban areas, will participate in the project. The findings will enhance the understanding of the social and psychological needs of this special group of migrants and will assist in the planning of immigration policies and culturally appropriate health services for older migrants.Read moreRead less
Examining the relationship between error processing, cognitive control and emotion: a cognitive neuroscience approach. The proposed research aims to contribute to current scientific thinking on how the processing of errors influences self-monitoring and cognitive performance. The ability to monitor one's cognitive performance deteriorates with normal ageing, and is particularly affected in a range of clinical conditions, where it is a reliable predictor of a poor prognostic outcome. This project ....Examining the relationship between error processing, cognitive control and emotion: a cognitive neuroscience approach. The proposed research aims to contribute to current scientific thinking on how the processing of errors influences self-monitoring and cognitive performance. The ability to monitor one's cognitive performance deteriorates with normal ageing, and is particularly affected in a range of clinical conditions, where it is a reliable predictor of a poor prognostic outcome. This project aims to clarify understanding of the cognitive and neural processes underlying self-monitoring, as an important first step to improving rehabilitation and management methods for age-related impairments such as Alzheimer's disease, and prominent mental health conditions such as schizophrenia.Read moreRead less
Improving cognitive function in the elderly. The ageing population has been identified as one of the major issues facing contemporary Australian society. For Australia, human ageing has significant societal, economic and, importantly, personal/human costs. The economic costs associated with ageing reflect decreased productivity as well as a higher incidence of a variety of illnesses including cardiovascular and respiratory disease and, importantly, neurological conditions such as Parkinson's dis ....Improving cognitive function in the elderly. The ageing population has been identified as one of the major issues facing contemporary Australian society. For Australia, human ageing has significant societal, economic and, importantly, personal/human costs. The economic costs associated with ageing reflect decreased productivity as well as a higher incidence of a variety of illnesses including cardiovascular and respiratory disease and, importantly, neurological conditions such as Parkinson's disease (PD) and Alzheimer's disease (AD). We will complete two large scale studies examining the efficacy of twelve months administration of two pharmacologically active supplements in reducing the cognitive effects of aging in elderly participants.

This project contributes directly to Promoting and Maintaining Good Health: Ageing well, ageing productively by placing a high value on the skills of older Australians and encouraging them to remain productive into retirement by sharing these skills. This project will also strengthen the social and economic fabric of rural communities by addressing the identified national priority area of skills shortages in rural areas by providing rural councils with a means to access skilled professionals to assist them in enhancing their economic and social sustainability. Further, use of sound, well-tested psychological theories of individual decision making will enhance the validity and applicability of the model.Read moreRead less
Cardiovascular and Respiratory Activity During Sleep Onset. Going to sleep requires that behavioural and physiological activities be modified. This is achieved by the integrated activity of sleep mechanisms and the circadian system. In this project we will investigate the nature of the regulatory control exerted by sleep mechanisms over respiration and cardiovascular activity at sleep onset, how sleep control interacts with circadian influence, and the nature of cardio-respiratory activity when ....Cardiovascular and Respiratory Activity During Sleep Onset. Going to sleep requires that behavioural and physiological activities be modified. This is achieved by the integrated activity of sleep mechanisms and the circadian system. In this project we will investigate the nature of the regulatory control exerted by sleep mechanisms over respiration and cardiovascular activity at sleep onset, how sleep control interacts with circadian influence, and the nature of cardio-respiratory activity when sleep control is removed at an arousal from sleep. It is anticipated that a better understanding of the regulatory control exerted by sleep over other systems will improve our understanding of sleep disorders.Read moreRead less
Respiratory and Cardiovascular Activation at Arousal from Sleep. An arousal from sleep, no matter how brief, is assciated with increased activity in the respiratory and cardiac systems. Under normal circumstances the response is considered adaptive. However, in disorders of sleep in which individuals arouse frequently and their sleep is fragmented, such as in Obstructive Sleep Apnea, the phenomenon has been linked to hypertension. While the clinical consequences of sleep fragmentation are now ap ....Respiratory and Cardiovascular Activation at Arousal from Sleep. An arousal from sleep, no matter how brief, is assciated with increased activity in the respiratory and cardiac systems. Under normal circumstances the response is considered adaptive. However, in disorders of sleep in which individuals arouse frequently and their sleep is fragmented, such as in Obstructive Sleep Apnea, the phenomenon has been linked to hypertension. While the clinical consequences of sleep fragmentation are now apparent, the mechanism that causes the increase in physiological activity at each arousal, is not known. The aim of this project will provide insight into the mechanism that produces the activation response and provide a basis for minimising the cardiac consequences of sleep disorders.Read moreRead less
