Comparison of Techniques for the Removal of Ocular Artefact from the Electroencephalogram: A Validation Study. Although employed extensively for both research and clinical purposes, the utility of the electroencephalograph (EEG) is hampered by the contaminating effects of eye movements on these 'brain waves'. If it can be validated, the recent Australian development of a solution to this problem will mean that the EEG can be measured more quickly and accurately. This purpose of this research is ....Comparison of Techniques for the Removal of Ocular Artefact from the Electroencephalogram: A Validation Study.

If it can be validated, the recent Australian development of a solution to this problem will mean that the EEG can be measured more quickly and accurately. This purpose of this research is to perform this validation, and its success would mean both more efficient EEG recording for the country, as well as an enhanced scientific reputation.Read moreRead less
Towards direct imaging of neuronal currents with MRI. This project aims to develop novel neuronal current magnetic resonance imaging (nc-MRI) methods that harness the oscillatory behaviour of neuronal magnetic fields. Current methods of detecting neuronal activity in the living human brain have limited spatial and temporal resolution. Use of nc-MRI aims to overcome these limitations by imaging the effects on the MRI signal of small transient magnetic fields associated with neuronal activity.

This project aims to develop novel neuronal current magnetic resonance imaging (nc-MRI) methods that harness the oscillatory behaviour of neuronal magnetic fields. Current methods of detecting neuronal activity in the living human brain have limited spatial and temporal resolution. Use of nc-MRI aims to overcome these limitations by imaging the effects on the MRI signal of small transient magnetic fields associated with neuronal activity. Signal-to-noise ratio is at the limits of detectability using current imaging systems and nc-MRI is yet to be convincingly demonstrated. An integrated framework for simulating nc-MRI in the visual cortex is expected to be developed.Read moreRead less
Biophysics-informed deep learning framework for magnetic resonance imaging. This project aims to bring about a paradigm shift from the conventional non-quantitative magnetic resonance imaging to ultra-fast, quantitative, and artefact free imaging. This project integrates biophysics and artificial intelligence, and it is expected to bring new knowledge in both fields. The expected outcomes of this project include next generation magnetic resonance imaging methods with a fundamental shift in the ....Biophysics-informed deep learning framework for magnetic resonance imaging. This project aims to bring about a paradigm shift from the conventional non-quantitative magnetic resonance imaging to ultra-fast, quantitative, and artefact free imaging. This project integrates biophysics and artificial intelligence, and it is expected to bring new knowledge in both fields. The expected outcomes of this project include next generation magnetic resonance imaging methods with a fundamental shift in the approach to image artefacts and image quantification. This project is expected to advance both single subject and population level biomedical imaging with greater accuracy and cost-effectiveness. This project also promotes explainable and generalisable artificial intelligence in medical imaging.Read moreRead less
Non-invasive measurement of intracranial pressure by means of transcranial doppler blood flow and central aortic pressure. The investigation will produce a device that will aid doctors measuring brain pressure without drilling holes through the skull. The device will use the technology of an Australian company that has the only patented system to deduce the pressure in the brain by measuring pressure close to the heart and the brain and by recording the pressure pulse wave at the wrist. The comm ....Non-invasive measurement of intracranial pressure by means of transcranial doppler blood flow and central aortic pressure.

The device will use the technology of an Australian company that has the only patented system to deduce the pressure in the brain by measuring pressure close to the heart and the brain and by recording the pressure pulse wave at the wrist. The community benefit will be in terms of the safety and ease with which changes in pressure in the brain can be detected. It will also advance the world renowned Australian technology in a new area of application.Read moreRead less
The development and testing of a device to enhance the application of repetitive transcranial magnetic stimulation. This project aims to develop and evaluate a new device designed to substantially enhance the use of transcranial magnetic stimulation, a technology, which is increasingly being applied in the treatment of disorders such as depression, as well as in the study of normal and abnormal brain function.

The Centre of Excellence for Integrative Brain Function will address one of the greatest scientific challenges of the 21st century to understand how the brain works. We will investigate complex functions such as attention, prediction and decision-making, which require the coordination of information processing by many areas of the brain. This will require a highly collaborative approach involving neurobiologists, cognitive scientists, engineers and physicists, allowing us to translate our discoveries into novel technologies for the social and economic benefit of all Australians. We will also train a new generation of multidisciplinary researchers, and contribute our expertise to a range of public education and awareness programs.Read moreRead less
Investigating the intercellular trafficking of proteins and RNA and its relevance to neurodegenerative diseases. Alzheimer's and prion diseases are neurodegenerative disorders associated with protein misfolding. This project brings together similar features of these diseases using novel cell- and animal-based studies to develop a greater understanding of the molecular basis of these disorders.
Understanding how the brain uses sensory information to guide reaching and grasping movements. Reaching, grasping and manipulating objects are crucial aspects of our daily lives, which are performed so effortlessly that they tend to be taken for granted. We know however that these functions take a relatively long time to mature (think of a baby learning how to get an object), and that they can be impaired by brain lesions involving a region called the posterior parietal cortex. We also know that ....Understanding how the brain uses sensory information to guide reaching and grasping movements. Reaching, grasping and manipulating objects are crucial aspects of our daily lives, which are performed so effortlessly that they tend to be taken for granted. We know however that these functions take a relatively long time to mature (think of a baby learning how to get an object), and that they can be impaired by brain lesions involving a region called the posterior parietal cortex. We also know that this region has multiple subdivisions, but how exactly these interact in allowing the sensory information to guide arm and hand muscles is unknown. Discovering how this happens in terms of cellular interaction can have profound implications for the creation of new technologies such as artificial limbs and autonomous robots, and result in health benefits.Read moreRead less

Improved understanding of neurological processes is crucial to improving clinical outcomes for patients. MedVis will contribute in three ways: support development of new methods of interpretation and analysis of complex neurological studies, allowing current methods to be applied more efficiently, and enabling distributed simulations and visualisations in real-time from remote sites.
The leading-edge, grid-based, software and computational techniques developed for the project will enable visualization, analysis and modelling of massive volumes of image and other visualisation data. This capability is important in medical research where large visualisation data volumes are being created and studied by experts remote from each other.
