Summary
Traumatic brain injuries, often from motor vehicle accidents, devastate the lives of thousands of young Australians each year and can lead to changes in personality and emotional regulation. Frontal lobe damage may cause apathy, withdrawal and loss of motivation or a loss of control leading to poor inhibition and anger outbursts. In this project we trial some experimental approaches to improving emotion regulation including biofeedback, self-control therapy and direct cortical stimulation.

Summary
Motor vehicle accidents are a major cause of severe traumatic brain injury (TBI) leading to lifelong, crippling disability. In NSW alone, there are approximately 770 new cases of severe brain injury each year. These people require extensive inpatient rehabilitation and many go on to rely upon community resources for the rest of their lives. The social and economic cost of such injury is cumulative. TBI is mainly experienced by young adults (18-24 years of age) who have normal life expectancy and ....Motor vehicle accidents are a major cause of severe traumatic brain injury (TBI) leading to lifelong, crippling disability. In NSW alone, there are approximately 770 new cases of severe brain injury each year. These people require extensive inpatient rehabilitation and many go on to rely upon community resources for the rest of their lives. The social and economic cost of such injury is cumulative. TBI is mainly experienced by young adults (18-24 years of age) who have normal life expectancy and each year more casualties are added to this social burden. Adults with TBI frequently experience a reduction in social skills. Loss of social skills presents major obstacles to reintegration into the community by making the sufferer more taxing and less rewarding to interact with socially. This loss of social skills limits their ability to maintain pre-injury relationships, and often creates an off-putting first impression on potential new acquaintances that interferes with their ability to establish new relationships. The following project is designed to develop and evaluate a treatment program to enhance the TBI individual's ability to create a good first impression on meeting new acquaintances - e.g., potential employers, work colleagues, customers, and social acquaintances - and to engage in behaviour that is mutually rewarding. The project will inform current theoretical approaches to remediation, providing an examination of the modifiability of social skills deficits that are the result of underlying cognitive impairments. It will provide a systematic, integrated social skills treatment approach for both individuals and groups where there are currently very few. The identification and refinement of successful treatment techniques will increase the efficiency of brain injury rehabilitation in Australia, improve the quality of life for sufferers of TBI and their families, reduce cost of rehabilitation and reduce reliance upon community resources in the long term.Read moreRead less
Sensory Cortex Processing Changes Underlying Brain And Behaviour Deficits Caused By Traumatic Brain Injury

Summary
Traumatic brain injury (TBI) from physical head trauma causes behavior and cognitive deficits. The burden for victims, families and the community is enormous: total life-time expenses in moderate-to-severe TBI are estimated to be $8.6 billion in Australia. We aim to elucidate whether changes in how the brain processes sensory information could underlie TBI-induced deficits in complex behaviour and whether these changes will be ameliorated by the three currently-most-promising treatments for TBI.
Drug addiction is a major health and societal problem in Australia. Relapse is among the most fundamental problems for addicts. This project studies the behavioural and brain mechanisms for relapse to drug seeking. It studies why relapse is more likely in some places than others; the brain mechanisms for this contextual control over relapse; and how relapse to seeking drug rewards is similar to and different from relapse to seeking non-drug rewards.
Neurocognitive And Social Changes Associated With Unleaded Petrol Sniffing And Abstinence From Further Sniffing

Previously, we used culturally-appropriate assessments of brain function to test Aboriginal petrol sniffers from remote communities in northern Australia. This showed that recreational petrol sniffers who remained living in their communities showed some degree of brain dysfunction that affected their ability to concentrate, remember things, learn, control their emotions and control their behaviour. Petrol sniffing was then completely stopped in these communities. Two years later, among people who had shown brain dysfunction from sniffing petrol, our assessments showed some recovery of some of the brain damage caused by sniffing petrol. Initially, the current study aims to determine the longer-term outcomes for abstinent petrol sniffers by returning to these communities and assessing social and brain function outcomes in the original study participants, now over 10 years since they stopped sniffing petrol. The second part of the study will focus on the specific effects on the brain, behaviour and social function of sniffing unleaded petrol in comparison to leaded petrol, alcohol, other inhalants and polydrug use. It will also further investigate the time course of recovery of brain function and social outcomes in the immediate period following abstinence from petrol sniffing. This will involve recruiting petrol sniffers who move to outstation communities to stop sniffing, and have them perform brain function tests several times over the months or years that they spend recovering. These findings will enable the development of appropriate programs to minimise the harm from petrol sniffing. It will also establish an assessment protocol for the classification of petrol related brain damage that can be used by health professionals such as Aboriginal health workers, nurses and doctors.Read moreRead less
Studying The Two Hit Hypothesis Of Psychiatric Illness: Role Of Brain-derived Neurotrophic Factor (BDNF)

Summary
Early environmental factors may play an important role in the development of psychiatric illnesses, such as schizophrenia and depression. We will study an animal model which combines early developmental stress followed by treatment with a stress hormone or chronic cannabis use in adolescence. We will assess behavioural changes and the role of a growth factor in the brain, BDNF. This wil lead to a better understanding of the role of neurodevelopmental stress in psychiatric disease.

Summary
My research has 4 primary objectives, representing major gaps in current knowledge: 1. improve knowledge of recovery and determinants of post-concussive symptoms 2. establish the impact of child brain insult on socio-emotional function and identify contributing factors 3. develop an iPad based tool for socio-emotional function 4. evaluate and disseminate e-heath treatments for child brain insult
