This project aims to understand how electrical activity in the primary olfactory (piriform) cortex enables mice to recognise and remember odours. By using optical recording techniques together with genetic tools, the project expects to generate new knowledge about how the mammalian brain builds internal representations of the external world. Specific outcomes of the project include new insights into the functional architecture of the piriform cortex and fresh understanding of how olfactory information is encoded and stored in neural circuits. More broadly, the project aims to advance our understanding of how the brain works, with benefits for future improvements in artificial intelligence and brain-machine interfaces.Read moreRead less
Electrical properties of human dendrites. This project aims to determine the electrical properties of dendrites in human neurons. Dendrites are the primary site of synaptic input to neurons and their electrical properties play a key role in information processing in the brain. While we know much about the electrical properties of dendrites in other species, primarily rodents, little is known about the electrical properties of human dendrites. This project aims to address this gap in knowledge fo ....Electrical properties of human dendrites. This project aims to determine the electrical properties of dendrites in human neurons. Dendrites are the primary site of synaptic input to neurons and their electrical properties play a key role in information processing in the brain. While we know much about the electrical properties of dendrites in other species, primarily rodents, little is known about the electrical properties of human dendrites. This project aims to address this gap in knowledge for the first time. The results obtained will shed light on the mechanisms the brain uses to process information, and therefore will bring us a step closer to truly understanding ourselves.Read moreRead less
Resolving the Structures of Human Muscarinic M1 and M4 Receptors. Muscarinic receptors are vital for most basic human brain functions. These receptors are changed in schizophrenia and Alzheimer's disease. This project will determine the structure and localisation of two of these receptors in order to i) understand their roles in brain disorders and ii) develop drugs to treat disorders involving them.
Verified concurrent memory management on modern processors. This project aims to formally verify automatic memory managers in the presence of concurrency and the weakly ordered memory of modern processors. A new framework for verifying memory managers, reusable for a wide range of managed programming languages, target hardware, policies, and algorithms will be developed. Expected technical outcomes include improved techniques to ensure trustworthiness of the foundations on which critical softwar ....Verified concurrent memory management on modern processors. This project aims to formally verify automatic memory managers in the presence of concurrency and the weakly ordered memory of modern processors. A new framework for verifying memory managers, reusable for a wide range of managed programming languages, target hardware, policies, and algorithms will be developed. Expected technical outcomes include improved techniques to ensure trustworthiness of the foundations on which critical software infrastructures are built. This will significantly enhance the security of public and private cyber assets, and deliver applications that are more robust and trustworthy, across a range of critical infrastructure such as transportation, communication, energy and defence.Read moreRead less

Summary
Spatial control of nanoporous materials for microfabrication. Treatment of numerous medical conditions will be revolutionised by biomedical devices that can deliver or remove selected molecules in precise locations (for example oxygenation of tissues, release of antitumor agents, toxin neutralisation). New lithographic protocols will be developed to enable the use of nanoporous filters directly for such purposes.

Role of the superior colliculus in sensory processing. The ability of an organism to attend to, and orient towards, stimuli in the environment is critical for survival. In the mammalian brain, the principal brain region performing this function is the superior colliculus.

In the mammalian brain, the principal brain region performing this function is the superior colliculus. Despite its importance, little is known about the role the superior colliculus plays in sensory perception. This project addresses this issue by leveraging revolutionary new recording techniques to determine how the superior colliculus codes sensory information and ultimately drives behaviour. The outcomes will be of immediate benefit to scientists studying sensory processing and perceptual decision making, and will help keep Australia at the forefront of brain-inspired engineering and the neuroscience-based knowledge economy.Read moreRead less

Fast three-dimensional imaging of neural signal propagation using light-field microscopy. This project aims to use a light-field microscope to reveal the dynamics of sustained neural activity in the brain. The brain’s neurons are highly interconnected, so neural signals can be sustained in a repeating cycle.

This project aims to use a light-field microscope to reveal the dynamics of sustained neural activity in the brain. The brain’s neurons are highly interconnected, so neural signals can be sustained in a repeating cycle. While this may underlie tasks such as working memory, its role in information processing is unclear. Understanding information processing is vital for finding treatments for neurodegenerative disorders. To characterise this large-scale aspect of neural computation, this project measures neural activity at high speed across large numbers of neurons. This is expected to provide evidence of the nature of sustained activity which may in the future lead to treatments for neurodegenerative disorders.Read moreRead less
