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
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
Modelling human brain development with stem cells and biomaterials. With limited resources to directly study and advance our understanding of human neural development, this
proposal will establish models of 4 key stages. Employing innovative, interdisciplinary approaches, biomaterials will be fabricated to provide structural and chemical support for human stem cells during: (i) neural induction, (ii) specification into neuronal progenitor subpopulations, (iii) neuronal maturation and integration ....Modelling human brain development with stem cells and biomaterials. With limited resources to directly study and advance our understanding of human neural development, this
proposal will establish models of 4 key stages. Employing innovative, interdisciplinary approaches, biomaterials will be fabricated to provide structural and chemical support for human stem cells during: (i) neural induction, (ii) specification into neuronal progenitor subpopulations, (iii) neuronal maturation and integration into complex neural networks as well as, (iv) the organisation of neurons into larger 3-dimensional brain structures, namely folding of the human cortex. Further, biomaterials developed here have commercialisation potential, targeted at standardizing the culturing of human stem cells to defined neural populations.
