Are there common mechanisms for the inhibition of fear? Disorders of fear and anxiety affect up to 28% of Australians across their lives. This project studies how the brain inhibits fear and anxiety. It has four National Benefits. First, the knowledge generated by this project will contribute to coherent theoretical accounts of fear inhibition. Second, it will increase Australia's competitiveness and reputation in experimental psychology and behavioural neuroscience. Third, it will provide novel ....Are there common mechanisms for the inhibition of fear? Disorders of fear and anxiety affect up to 28% of Australians across their lives. This project studies how the brain inhibits fear and anxiety. It has four National Benefits. First, the knowledge generated by this project will contribute to coherent theoretical accounts of fear inhibition. Second, it will increase Australia's competitiveness and reputation in experimental psychology and behavioural neuroscience. Third, it will provide novel insights into ways of reducing anxiety and fear among sufferers of clinical anxiety disorders. Finally, it will provide internationally competitive training opportunities for Australian students.

The regulation of fear and attention: From genes to the brain to behaviour. Exposure to dangerous events elicits fear concomitant with attentional processing of environmental stimuli accompanying those events. However this fear and attention are typically inhibited so that they are restricted to dangerous events or stimuli which signal them. This project studies the role of endogenous opioids in the inhibition of fear and threat-related attention. It studies opioid inhibition in terms of its con ....The regulation of fear and attention: From genes to the brain to behaviour. Exposure to dangerous events elicits fear concomitant with attentional processing of environmental stimuli accompanying those events. However this fear and attention are typically inhibited so that they are restricted to dangerous events or stimuli which signal them. This project studies the role of endogenous opioids in the inhibition of fear and threat-related attention. It studies opioid inhibition in terms of its consequences for gene transcription, learning, and attention. It will provide the first integrated analysis of fear inhibition, from the level of the gene to the brain to behaviour. Thus, the project will provide significant insights into the biological complexity underpinning vulnerability to anxiety and fear.Read moreRead less
Predicting danger: The nature, consequences, and neural mechanisms of predictive fear learning. This project has four major national benefits. First, it addresses a fundamental scientific issue from a novel perspective to increase knowledge. By combining innovative approaches to study how the brain predicts danger, it will shed light on the relationship between brain and behaviour. Second, the project will contribute significantly to Australia's international competitiveness and reputation in ex ....Predicting danger: The nature, consequences, and neural mechanisms of predictive fear learning. This project has four major national benefits. First, it addresses a fundamental scientific issue from a novel perspective to increase knowledge. By combining innovative approaches to study how the brain predicts danger, it will shed light on the relationship between brain and behaviour. Second, the project will contribute significantly to Australia's international competitiveness and reputation in experimental psychology. Third, the knowledge generated by this project has the potential to improve the welfare of Australians by addressing an increasingly important health problem - anxiety. Finally, the project provides outstanding, internationally competitive, training opportunities for Australian students in Psychology.Read moreRead less
