Improving neuronal cell function with cell permeable copper complexes. Metal-based drugs offer an exciting new approach to treatment of neurodegeneration. However, little is known about how cells metabolise these drugs and this information is critical for further drug development. This project will determine how metal-based drugs are metabolised by neuronal cells and how this may result in therapeutic benefit.
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
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. 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 co ....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. 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
Coding of olfactory information in the piriform cortex. 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 pirifo ....Coding of olfactory information in the piriform cortex. 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
Analysing the protective role of platelets during malaria infection. Platelets protect the host during malarial infection. This project aims to study how platelets kill the malaria parasite by investigating the role of host molecules and their potential as novel antimalarial agents. The role of platelets in the pathogenesis of cerebral malaria syndrome will also be investigated.
Probing the four photosynthetic membrane protein complexes at work in situ in leaves. This proposal aims at sustainable improvements in plant productivity and photosynthetic adaptation in drastic Australian climates. In photosynthesis, membranes with the four multiprotein complexes use sunlight to make compounds that drive carbon assimilation. Instead of the usual dissection of photosynthetic membranes, this project will develop and refine the applicant's rapid, reliable, non-intrusive technique ....Probing the four photosynthetic membrane protein complexes at work in situ in leaves. This proposal aims at sustainable improvements in plant productivity and photosynthetic adaptation in drastic Australian climates. In photosynthesis, membranes with the four multiprotein complexes use sunlight to make compounds that drive carbon assimilation. Instead of the usual dissection of photosynthetic membranes, this project will develop and refine the applicant's rapid, reliable, non-intrusive techniques to probe the four membrane complexes at work in their native state in leaves. Two portable commercial instruments will potentially emerge from the techniques. This novel non-reductionist approach will identify key limitations to photosynthetic performance under stress, and insights into improvements for primary plant productivity.Read moreRead less
The cellulose synthase complex of the Arabidopsis primary cell wall. The polysaccharide cellulose is the basis for the wood and cotton fibre industries of Australia and much of our research on the mechanism of synthesis has been supported by those industries over the past decade. The present project focuses on the proteins making cellulose and how they organised into functional complexes that are able to make cellulose. The knowledge it provides, together with that from other projects, will move ....The cellulose synthase complex of the Arabidopsis primary cell wall. The polysaccharide cellulose is the basis for the wood and cotton fibre industries of Australia and much of our research on the mechanism of synthesis has been supported by those industries over the past decade. The present project focuses on the proteins making cellulose and how they organised into functional complexes that are able to make cellulose. The knowledge it provides, together with that from other projects, will move us towards the situation where we can manipulate the rate at which cellulose is produced and change its detailed properties. This opens the way to industry producing fibres with more desirable properties and producing novel cellulose-based materials tailored to specific applications.Read moreRead less
Functional Genomic Analysis of Exported DNAJ Molecules in the Malaria Parasite Plasmodium falciparum. Malaria is not only a global health problem, but also affects countries surrounding Australia like PNG and Indonesia, reducing the region's stability and prosperity. Environmental changes and increased mobility of people (eg. aid and security personnel) make Australia itself more prone to malaria.

Malaria is not only a global health problem, but also affects countries surrounding Australia like PNG and Indonesia, reducing the region's stability and prosperity. Environmental changes and increased mobility of people (eg. aid and security personnel) make Australia itself more prone to malaria. The project will translate recent genomic data into functional insights using frontier technology to identify new intervention targets for P. falciparum infection. Developing novel targets is mandated by humanity, and also to safeguard Australia's region against the social and economical implication of this disease. An Australian developed intervention would increase the global visibility of its science, leading to increased investments.Read moreRead less
