Central pathways regulating visceral pain. This project aims to investigate the neural pathways within the spinal cord and brain processing colorectal pain perception. The project aims to identify the spinal cord neurons relaying colorectal signalling into the brain and the influence of descending modulation from the brainstem upon these pathways. The outcomes will greatly benefit fundamental understanding of the central pathways processing visceral pain.
Left of centre: Attentional distortions in the mental representation of space in healthy and clinical populations. Stroke patients cost the Australian economy $1.3bn pa in addition to their social burden, but effective diagnosis and rehabilitation is impeded by a lack of fundamental research into the cognitive and neural mechanisms that underlie attentional disorders. Our research will provide significant new insights into how the brain deploys attention in external and imagined space and will l ....Left of centre: Attentional distortions in the mental representation of space in healthy and clinical populations. Stroke patients cost the Australian economy $1.3bn pa in addition to their social burden, but effective diagnosis and rehabilitation is impeded by a lack of fundamental research into the cognitive and neural mechanisms that underlie attentional disorders. Our research will provide significant new insights into how the brain deploys attention in external and imagined space and will lead to more effective management and treatment of stroke victims. Our new test of attentional disorders is independent of a patient's inability to see or move and will enable more effective diagnosis. Our research provides the fundamental knowledge base for our discipline and is vital for developing the next generation of Australia's cognitive neuroscientists. Read moreRead less
Left to right is front to back: attentional distortions in near and far space for healthy and clinical populations. We are investigating a perceptual bias that makes people think objects right in front of them are actually slightly to the right but objects far away are slightly to the left. This project will help understand why this happens, to help reduce traffic collisions and help people with brain damage that causes similar perceptual biases.
Attentional asymmetries for navigation in healthy and clinical groups. This project plans to investigate how differences in attentional capacity between the left and right sides of the brain affect the ability to walk or manoeuvre vehicles between obstacles. To navigate our environment and avoid obstacles, we need to attend to stimuli that are important and ignore those that are not. Unfortunately, the brain’s attentional capacity is limited, which can result in errors and collisions. Using the ....Attentional asymmetries for navigation in healthy and clinical groups. This project plans to investigate how differences in attentional capacity between the left and right sides of the brain affect the ability to walk or manoeuvre vehicles between obstacles. To navigate our environment and avoid obstacles, we need to attend to stimuli that are important and ignore those that are not. Unfortunately, the brain’s attentional capacity is limited, which can result in errors and collisions. Using the techniques of cognitive neuroscience, the project aims to provide a better understanding of the cognitive and neural mechanisms that govern attention in an applied setting. It expects to identify the factors that exacerbate lapses in attention and collisions. The effect of everyday impediments such as mobile phones, alcohol and fatigue will be investigated together with means of minimising these attentional lapses and improving safety.Read moreRead less
Hierarchical information processing in the primate visual cortex. This project aims to understand how visual information is transformed across hierarchical levels in the brain. Neuroscientists have long recognised that the visual cortex can be conceptualised as a hierarchical processing network. This became apparent when learning algorithms based on hierarchical networks ("deep learning") changed artificial intelligence. This project will combine high-throughput electrophysiology with analytical ....Hierarchical information processing in the primate visual cortex. This project aims to understand how visual information is transformed across hierarchical levels in the brain. Neuroscientists have long recognised that the visual cortex can be conceptualised as a hierarchical processing network. This became apparent when learning algorithms based on hierarchical networks ("deep learning") changed artificial intelligence. This project will combine high-throughput electrophysiology with analytical tools adopted from deep learning. By explaining the physiological properties of higher-level neurons in terms of hierarchical networks, the project expects to address long standing questions in neuroscience, and provide insights on biological hierarchical computation.Read moreRead less
