Common synaptic inputs to human upper airway muscles. Changes in the activity of upper airway muscles at sleep onset contribute to the development of Obstructive Sleep Apnoea. The aim of this project is to investigate how the brain controls upper airway muscles during wakefulness and sleep and to identify the pathological processes that lead to the development of Obstructive Sleep Apnoea.
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
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

Unravelling the relationship between food and the brain. This project aims to investigate how highly palatable foods that are high in fat and sugar, interact with the brain to cause their overconsumption. Highly palatable foods cause plasticity in brain reward circuitry in a manner similar to drugs of abuse. Identifying how these "junk" foods interact with reward areas of the brain will explore the neural mechanisms underlying the hedonic nature of appetite. This project will not only inform our ....Unravelling the relationship between food and the brain. This project aims to investigate how highly palatable foods that are high in fat and sugar, interact with the brain to cause their overconsumption. Highly palatable foods cause plasticity in brain reward circuitry in a manner similar to drugs of abuse. Identifying how these "junk" foods interact with reward areas of the brain will explore the neural mechanisms underlying the hedonic nature of appetite. This project will not only inform our understanding of how exposure to these foods can contribute to overeating and obesity, a huge and growing problem in Australia, but will also provide evidence to inform policy options relevant to advertising and marketing of these foods.Read moreRead less

Gene-environment interactions in the regulation of neuroplasticity and cognitive function . This project will study the effects of different housing conditions on neuroplasticity-related cognitive function by combining an innovative operant conditioning behavioural test (computerised touch-screen technology) and new molecular approaches.

This project will study the effects of different housing conditions on neuroplasticity-related cognitive function by combining an innovative operant conditioning behavioural test (computerised touch-screen technology) and new molecular approaches. Potential gene-environment interactions will be revealed using genetically targeted mice which have never been assessed in that context (mutants with altered glucocorticoid and serotonin signalling). This project will study whether specific stages of the neuroplasticity process are differentially modulated through gene-environment interactions, ultimately resulting in changes to behaviour and cognitive functions. This will lead to a better understanding of the potential approaches that could be used to improve cognitive function.Read moreRead less

Summary
Contribution of basal ganglia networks to the fine-tuning of action. This project aims to identify the changes occurring in specific brain circuits when new behaviours are learned. Our ability to perform efficient goal-directed actions involves a learning process in which separate movements are organised into sequences of action. This project aims to determine how this is encoded in the brain by mapping basal ganglia networks that are directly engaged during different stages of learning. This pr ....Contribution of basal ganglia networks to the fine-tuning of action. This project aims to identify the changes occurring in specific brain circuits when new behaviours are learned. Our ability to perform efficient goal-directed actions involves a learning process in which separate movements are organised into sequences of action. This project aims to determine how this is encoded in the brain by mapping basal ganglia networks that are directly engaged during different stages of learning. This project also seeks to identify specific neural circuits that are important for the refinement of action. The knowledge developed in this project is expected to support the development of training programs to instruct individuals in specialised tasks and may be used in the design of biologically inspired robots.Read moreRead less

This Project seeks to establish the rules that govern the integration of learning in brain reward systems by studying how neuronal circuits change their molecular signatures as animals assimilate new knowledge. These studies will combine novel experimental designs to investigate learning with multidisciplinary methods for mapping, recording and functionalising teaching signals in behaving mice. The outcomes will create a significant shift in our understanding of the neural bases that underlie reward learning, and will critically expand the field by providing a new model of learning integration in brain systems.Read moreRead less
