Summary
Facility for analysing behaviour, learning and motor skills in animal models. Mental disorders are one of the largest costs to the community today and account for more than 50% of the time lost from work. Moreover, these disorders are disabling conditions that relate to fundamental, basic questions of identity and individuality. This collaborative behavioural facility at The University of Queensland will underpin excellent research into how neurological changes affect behaviour and thinking, pro ....Facility for analysing behaviour, learning and motor skills in animal models. Mental disorders are one of the largest costs to the community today and account for more than 50% of the time lost from work. Moreover, these disorders are disabling conditions that relate to fundamental, basic questions of identity and individuality. This collaborative behavioural facility at The University of Queensland will underpin excellent research into how neurological changes affect behaviour and thinking, provide infrastructure to test current models on brain functions, and support the development of new compounds to treat these disorders, thus resulting in significant national and community benefits in improved health outcomes and increased work productivity.Read moreRead less
Operation of nerve cell networks in the neocortex. In humans, intellectual disabilities occur when nerve cells in the neocortex, the most complicated area of the brain, fail to function correctly. The goal of this project is to understand how neocortical areas communicate and how changes in the structure of neurons disturb their function; work that will lead to a better understanding of the operation of the neocortex.
Assembly of neural circuits during development. This program aims to understand how nerve cells wire up accurately during development. Specifically, the program will determine how neuronal connections are established in the retina to produce a sensory structure essential for vision. The program will also generate innovative tools for watching in live animals, the making and breaking of connections during normal and abnormal development. Discoveries will not only significantly increase our knowle ....Assembly of neural circuits during development. This program aims to understand how nerve cells wire up accurately during development. Specifically, the program will determine how neuronal connections are established in the retina to produce a sensory structure essential for vision. The program will also generate innovative tools for watching in live animals, the making and breaking of connections during normal and abnormal development. Discoveries will not only significantly increase our knowledge base of how the nervous system develops or degenerates, but the results will provide crucial information for future studies based on genetic approaches, drug therapies and bioengineering technology to repair the injured nervous system.Read moreRead less
Mechanisms of fear learning and extinction in the mammalian brain. The brain is a remarkable machine that coordinates all aspects of our daily lives including the storage and retrieval of memories. Given that many age-related degenerative disorders are associated with marked changes in learning and memory it also has implications for Australia's National Research Priority 2 "Ageing well and ageing productively". This research aims to discover the basic mechanisms that underlie memory storage an ....Mechanisms of fear learning and extinction in the mammalian brain. The brain is a remarkable machine that coordinates all aspects of our daily lives including the storage and retrieval of memories. Given that many age-related degenerative disorders are associated with marked changes in learning and memory it also has implications for Australia's National Research Priority 2 "Ageing well and ageing productively". This research aims to discover the basic mechanisms that underlie memory storage and how these are modulated in an emotional context. It will also shed light on states such as anxiety, depression and post-traumatic stress, enhancing our ability to identify new therapeutic targets for such disorders.Read moreRead less
Dendritic information processing during sensory-motor behaviour. The neocortex is centrally involved in the control of animal behaviour. It is largely unknown how neocortical neurons contribute to the neuronal computations that generate behaviour. The project will study how individual neurons in the neocortex compute the sensory and motor signals that underlie an important exploratory behaviour in rodents.
Neural mechanisms of attention in the honeybee and Drosophila melanogaster. By examining convergent neural mechanisms of attention in insects and comparing these mechanisms to those found in vertebrates, we may uncover basic principles of how attention operates in widely divergent systems. This type of basic scientific research could be used to provide a framework to develop better approaches for treatment for individuals with defects in attention. Such defects are symptoms of several psycholo ....Neural mechanisms of attention in the honeybee and Drosophila melanogaster. By examining convergent neural mechanisms of attention in insects and comparing these mechanisms to those found in vertebrates, we may uncover basic principles of how attention operates in widely divergent systems. This type of basic scientific research could be used to provide a framework to develop better approaches for treatment for individuals with defects in attention. Such defects are symptoms of several psychological conditions, including attention deficit disorder, autism, and schizophrenia, which have major social and economic costs in Australia. Therefore, by expanding our understanding of how attention operates at the level of neurons, we can begin to develop targeted treatments for addressing these conditions. Read moreRead less
Processing of social communication calls in primate auditory cortex. This research will advance our understanding of the brain mechanisms involved in perception of sound. This will help to understand disorders of speech and hearing following brain damage and may assist in efforts to develop better hearing aids, as well as other speech recognition technologies. In addition, we will develop a primate for studying processing of sound in the brain that will be useful in future research to develop ....Processing of social communication calls in primate auditory cortex.

Using toxins to understand the mechanisms of pain. Toxins have evolved in plants, animals and microbes as part of defensive and/or prey capture strategies, and have proven to be invaluable research tools as well as providing leads for potential new therapies. This project will use subtype-selective toxins to define the role of ion channels in pain, using novel pathway-specific and disease-specific animal models of pain. The findings from this project will provide significant insight into the ne ....Using toxins to understand the mechanisms of pain.

This project will use subtype-selective toxins to define the role of ion channels in pain, using novel pathway-specific and disease-specific animal models of pain. The findings from this project will provide significant insight into the neuropharmacology of pain, will lead to the identification of novel molecular targets with analgesic potential and is expected to provide novel treatment approaches for pain.Read moreRead less
Novel EEG data mining methods for detecting and monitoring brain injury. The outcomes of this project could ultimately help produce novel technology which would enable bedside monitoring of brain function in patients with brain injuries such as stroke. This technology could aid critical care and treatment of such patients. Hence patients' recoveries could be positively affected and the high death or disability rates associated with such conditions could be reduced.

The outcomes of this project could ultimately help produce novel technology which would enable bedside monitoring of brain function in patients with brain injuries such as stroke. This technology could aid critical care and treatment of such patients. Hence patients' recoveries could be positively affected and the high death or disability rates associated with such conditions could be reduced. A host of economic and social benefits for patients, their families, hospitals and their staff, governments and healthcare organisations could thus result. The developed technology would be non-invasive, compact and relatively inexpensive, and could thus be used in rural and regional hospitals, thereby also benefiting patients in those communities.
