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
The impact of female sex hormones on neurodevelopment. This project aims to characterise the contribution of sex hormones to the development of emotional brain circuits in female adolescents. Puberty is associated with profound changes in emotional behaviours in females, but we know little about the underlying brain mechanisms. In particular, research has neglected to consider the role of the sex hormones for which changes are a defining feature of female puberty (eg, oestradiol). This work will ....The impact of female sex hormones on neurodevelopment. This project aims to characterise the contribution of sex hormones to the development of emotional brain circuits in female adolescents. Puberty is associated with profound changes in emotional behaviours in females, but we know little about the underlying brain mechanisms. In particular, research has neglected to consider the role of the sex hormones for which changes are a defining feature of female puberty (eg, oestradiol). This work will be the first to comprehensively advance our understanding of the unique role of sex hormones in shaping the adolescent female brain. It will provide critical understanding of how individual differences in hormonal factors increase risk for emotional problems in females, and inform treatment strategies.Read moreRead less
Studying the effects of repetitive transcranial magnetic stimulation with near Infrared spectroscopy. Repetitive transcranial magnetic stimulation (rTMS) is increasingly being used as a tool in studying human and animal brain function and in the treatment of brain disorders but there are fundamental gaps in our understanding of its basic mechanisms of action and hence our capacity to optimise protocols. This research will use near infrared spectroscopy to study the range of potential ways of alt ....Studying the effects of repetitive transcranial magnetic stimulation with near Infrared spectroscopy. Repetitive transcranial magnetic stimulation (rTMS) is increasingly being used as a tool in studying human and animal brain function and in the treatment of brain disorders but there are fundamental gaps in our understanding of its basic mechanisms of action and hence our capacity to optimise protocols. This research will use near infrared spectroscopy to study the range of potential ways of altering brain activity with rTMS. It will substantially enhance the applicability of the technique ultimately improving our knowledge of human and animal brain function and outcomes for patients with depression and other disorders. It will help reinforce Australia as a leading country in the development of brain stimulation techniques.Read moreRead less
Structural-functional connectivity in the brain. This project aims to develop magnetic resonance imaging analysis methods to non-invasively study brain connectivity. Recent advances in imaging can comprehensively describe the brain’s complex network of functional and structural connections (the brain ‘connectome’). This project will simultaneously investigate structural and functional connectivity, and characterise the dynamic properties of the connectome using graph-theoretic approaches. This p ....Structural-functional connectivity in the brain. This project aims to develop magnetic resonance imaging analysis methods to non-invasively study brain connectivity. Recent advances in imaging can comprehensively describe the brain’s complex network of functional and structural connections (the brain ‘connectome’). This project will simultaneously investigate structural and functional connectivity, and characterise the dynamic properties of the connectome using graph-theoretic approaches. This project should give neuroscientists computational tools to comprehensively map the network architecture of the human brain.Read moreRead less
The development of the social brain in early childhood. This project aims to understand how the human brain develops social and emotional understanding. The brain has remarkable abilities for understanding our social environment, such as inferring other people’s thoughts and feelings. This project will use neuroscience techniques to investigate how brain networks combine to produce social understanding, how this changes throughout child development, and how it relates to complex social behaviour ....The development of the social brain in early childhood. This project aims to understand how the human brain develops social and emotional understanding. The brain has remarkable abilities for understanding our social environment, such as inferring other people’s thoughts and feelings. This project will use neuroscience techniques to investigate how brain networks combine to produce social understanding, how this changes throughout child development, and how it relates to complex social behaviours. This project’s findings could be used to develop educational programmes that enhance empathy and co-operation, strengthen family relationships, promote social inclusion and reduce maladaptive behaviours. It could also guide intervention in brain disorders that affect social understanding.Read moreRead less

What is the functional significance of mirror neurons? Contrasting the adaptation and association models of the mirror neuron system. Mirror neurons are a type of brain cell that are thought to underlie empathy and cause autism. Alternatively, however, mirror neurons might instead arise from repeated associations between what we see and what we do. This study uses brain stimulation and neuroimaging techniques to determine the function of mirror neurons.

Summary
Extinction of drug-seeking in adolescent rats. To investigate the ontogeny of drug abuse and its treatment, acquisition and treatment of drug-seeking behaviour will be examined in adolescent rats. I expect that adolescent rats will fail to inhibit drug-seeking behaviour, and show immaturity in cortical brain areas. Increasing cortical activity may rescue their ability to inhibit drug-seeking.

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. Potential gene-environment interactions will be revealed using genetically targeted mice which have never been assessed in that context (mutants with altered gl ....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. 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

The National Research Priorities include 'ageing well, ageing productively'. Within this priority, it is necessary to be inclusive of those who have ongoing disabilities and/or chronic disease. This project aims to facilitate healthy lifestyles and community involvement in a group who have significant barriers to achieving their potential. The high incidence of depression and poor quality of life in stroke survivors and their carers emphasises the need to enhance wellness in these people. The study will develop a model for promoting recovery and community reintegration in stroke survivors, with the goal of enabling stroke survivors and their carers to actively participate in the community and pursue personal goals.Read moreRead less
