Empathy, Attention and Reasoning: The role of automatic and controlled processing in emotion recognition following traumatic brain injury. Traumatically brain injured adults have difficulty identifying emotional facial expressions but little is known regarding their psychophysiological reactions to emotional expression, the efficacy of their visual search patterns of facial features or the extent to which they engage conscious processing and problem solving to assist interpretation. Nor is anyth ....Empathy, Attention and Reasoning: The role of automatic and controlled processing in emotion recognition following traumatic brain injury. Traumatically brain injured adults have difficulty identifying emotional facial expressions but little is known regarding their psychophysiological reactions to emotional expression, the efficacy of their visual search patterns of facial features or the extent to which they engage conscious processing and problem solving to assist interpretation. Nor is anything known about their ability to recognise dynamic emotional displays compared to photographs. This project examines each of these facets using static and dynamic portrayals. The project will inform neuropsychological theories of facial processing, test the ecological validity of previous research and improve understanding of psychosocial deficits after TBI and their treatment.Read moreRead less
Exploring the brain mechanisms underlying hyperactivity in Attention-Deficit/Hyperactivity Disorder. Attention-deficit/Hyperactivity Disorder (AD/HD) is the most common psychiatric disorder affecting children, resulting in substantial costs (both human and financial) to the child, their family and Australian society.

Attention-deficit/Hyperactivity Disorder (AD/HD) is the most common psychiatric disorder affecting children, resulting in substantial costs (both human and financial) to the child, their family and Australian society. The outcomes of this project will provide a better foundation for understanding dysfunctional brain mechanisms in AD/HD, which is expected to lead to better diagnosis, treatment, and community support. Ultimately this will contribute to a healthy start to life for these children. This project will also demonstrate how an integrated Australian approach can lead the research agenda in both basic neuroscience, at the interface of psychology and physiology, and its applications in health.Read moreRead less
Central nervous system cytokines and morphine analgesia. Morphine remains the drug of choice for the management of moderate-to-severe pain, however its clinical effectiveness is compromised by the fact that morphine's analgesic (pain reducing) efficacy becomes less effective the more it is administered..

Morphine remains the drug of choice for the management of moderate-to-severe pain, however its clinical effectiveness is compromised by the fact that morphine's analgesic (pain reducing) efficacy becomes less effective the more it is administered.. This project will examine how analgesic tolerance develops from a completely new approach: Namely, how stimulation of the immune system within the central nervous system is a crucial factor in the development of tolerance. Modulation of analgesia by the immune system has not been systematically studied and provides a potentially fertile ground for the development of new techniques in the management of clinical pain.Read moreRead less
The role of context in the acquisition, extinction and reinstatement of fear. Behavioural studies have identified a role for context in the development, extinction and reactivation of fear memories. Although there has been significant progress in delineating the neural pathways for fear conditioning, less is known about the substrates that represent the context of conditioning. This project studies the neural substrates of the processes by which context controls the acquisition, extinction and r ....The role of context in the acquisition, extinction and reinstatement of fear. Behavioural studies have identified a role for context in the development, extinction and reactivation of fear memories. Although there has been significant progress in delineating the neural pathways for fear conditioning, less is known about the substrates that represent the context of conditioning. This project studies the neural substrates of the processes by which context controls the acquisition, extinction and reactivation of fear memories. Specifically, it examines the role of information flow between the dorsal subiculum and the accumbens nucleus in the processes by which rats learn about environmental context and the control exerted by such contexts on fear memories.Read moreRead less
Validation of a New Conceptual Model of ADHD based on Underlying Central Nervous System Dysfunction. ADHD is a debilitating problem that affects 5% of children and approximately half as many adults. ADHD causes substantial problems at school and if untreated, predisposes the individual to increased drug and alcohol use, marital breakdown, criminal prosecution and psychiatric problems in later life. One problem is that we do not fully understand what are the causes of the disorder. This project w ....Validation of a New Conceptual Model of ADHD based on Underlying Central Nervous System Dysfunction. ADHD is a debilitating problem that affects 5% of children and approximately half as many adults. ADHD causes substantial problems at school and if untreated, predisposes the individual to increased drug and alcohol use, marital breakdown, criminal prosecution and psychiatric problems in later life. One problem is that we do not fully understand what are the causes of the disorder. This project will test the validity of several models of brain dysfunction in ADHD which have been influential in the literature, but poorly tested. Through better understanding of the basic underlying problems, more effective intervention can be developed.Read moreRead less

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

How satiation control reward value and cue-induced appetitive behaviours. This proposal aims to identify mechanisms that control environment-driven food-seeking behaviours. It seeks to do so by using modern virally-mediated and basic behavioural as well as histological techniques in a transgenic rat to characterise novel hindbrain circuits that control these feeding behaviours. This is significant as environment-driven overeating is problematic yet underlying mechanisms are unclear. This project ....How satiation control reward value and cue-induced appetitive behaviours. This proposal aims to identify mechanisms that control environment-driven food-seeking behaviours. It seeks to do so by using modern virally-mediated and basic behavioural as well as histological techniques in a transgenic rat to characterise novel hindbrain circuits that control these feeding behaviours. This is significant as environment-driven overeating is problematic yet underlying mechanisms are unclear. This project expects to provide new knowledge on when, where and how hindbrain neurons control environment-driven food-seeking behaviours. This should provide benefits to the advancement of knowledge on the neural mechanisms of food-seeking and provide a basic science platform for future research on the study of feeding behaviours.
