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
Action-related learning and plasticity in the cortico-striatal network. This project focuses on the neural bases of adaptive behaviour, specifically on the neural processes through which new actions are acquired. This project aims to establish the neural networks involved as well as the locus of the critical cellular plasticity mediating this learning process in the brain.
