When is extinction not extinction? Disorders of fear and anxiety are widespread and impose significant burdens on individual sufferers and their families. This projects studies new ways of augmenting loss of fear and will identify the important behavioural mechanisms as well as critical brain pathways for this fear loss.
Uncertainty and response control in the prefrontal cortex. This project will identify how complex behaviours come to be performed habitually. It is proposed that statistical certainty in the learning environment is a key determinant of automatic behaviour, that detection of uncertainty can restore voluntary control of behaviour and that this is an important function of the prefrontal cortex of the brain.
Into the thirties: Persistence and social consequences of risky drinking. The aim of this project is to investigate the social contexts, roles and consequences of problematic alcohol use in adults aged 30, using long term longitudinal resources able to observe the development and corollary of alcohol use over time. It is posited that such drinkers entering their third decade of life persist in levels of problematic alcohol use typically associated with younger ages and that this leads to social ....Into the thirties: Persistence and social consequences of risky drinking. The aim of this project is to investigate the social contexts, roles and consequences of problematic alcohol use in adults aged 30, using long term longitudinal resources able to observe the development and corollary of alcohol use over time. It is posited that such drinkers entering their third decade of life persist in levels of problematic alcohol use typically associated with younger ages and that this leads to social consequences, such as gender specific risks, relationship conflicts and more severe long term effects. Outcomes from this project are expected to inform the generation of relevant prevention and intervention strategies aimed to address problem drinking in adult Australians.Read moreRead less

Molecular mechanisms causing relapse. This project aims to identify the neural connectivity and molecular profile of ventral pallidal neurons in the brain that control drug and alcohol addiction, relapsing disorders where users lose the ability to inhibit drug seeking behaviour. This project integrates neurobiological and psychological attributes of relapse. The anticipated outcomes provide insights about molecular mechanisms causing relapse, and expand knowledge of brain mechanisms that contrib ....Molecular mechanisms causing relapse. This project aims to identify the neural connectivity and molecular profile of ventral pallidal neurons in the brain that control drug and alcohol addiction, relapsing disorders where users lose the ability to inhibit drug seeking behaviour. This project integrates neurobiological and psychological attributes of relapse. The anticipated outcomes provide insights about molecular mechanisms causing relapse, and expand knowledge of brain mechanisms that contribute to relapsing disorders such as drug addiction and obesity. The findings from this project could be used to reduce relapse, and hence reduce the burden of alcohol related problems on health, the community and the Australian economy.Read moreRead less
Cannabis and the brain: the good, the bad and the unknown. Cannabis is the most widely used illicit drug but much remains unknown about how it affects the brain. This research will examine effects on brain cells through to whole brain function in humans to determine how cannabis use may lead to impaired thinking or psychological symptoms and why cannabis might affect individuals in different ways.
