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
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
Pathogenesis And Therapeutic Modulation Of Aggressive Behaviour In A Mouse Model Of Autism Spectrum Disorder
Funder

Funding Amount
$583,015.00
Summary
This project focuses on understanding the causes of aggressive behaviour in mice that have a human gene mutation found in autism. Aggressive behaviour is common in autism patients and can have severe consequences on education and employment opportunities. These mice also show excess dampening of brain function (inhibition). This project will test if aggression in these mice is caused by altered inhibition.
Gene-environment Interactions Modulating Cortical And Cognitive Dysfunction

Summary
A feature of many major brain disorders, including schizophrenia and dementia, is disruption of cognition. A key brain area impacted in such cognitive disorders is the prefrontal cortex. This project will use clinically translatable touchscreen to understand how this aspect of brain dysfunction causes abnormal cognition. We will investigate the mechanisms involved, using highly innovative approaches, which will contribute to the development of new treatments for such cognitive disorders.
Characterisation Of Eurl, A Novel Gene Implicated In The Etiology Of Abnormal Brain Development And Intellectual Disability

Funding Amount
$597,541.00
Summary
Intellectual disability affects around one per cent of Australians, and can arise from genetic abnormalities during fetal life, such as through abnormal regulation of gene expression. We have identified a novel gene, known as eurl, which controls brain assembly as well as the ability of neurons to form functional connections within the brain. We will investigate how this novel gene controls brain development, and characterise eurl as a potential therapeutic target for learning and memory.
Understanding the contribution of neuroinflammation in acute and chronic neural injury. A major focus of this project will be investigating the involvement of neuroinflammation in neural cell damage. It will explore how neuroinflammation contributes to this damage in both acute and chronic neuropathologies.
Regulation of neuronal cell death signalling for the treatment of neurodegenerative diseases. The progression of neurodegenerative diseases, such as Alzheimer's and motor neuron diseases, are often underpinned by neuronal cell death-signalling. This project aims to characterise molecules that regulate cell death signalling, thereby increasing our knowledge of how neuronal cell death can be inhibited.
Molecular And Cellular Mechanisms Of Axon Guidance In The Vertebrate Nervous System

Summary
There are, at least, two major obstacles that have to be overcome in the design of therapies to assist the repair of injured brain tissue. First, the nerve cells that are damaged have to be encouraged to regrow - typically this regrowth is inhibited in the brain; and second, this regrowth has to be directed so that the correct connections are re-established. This project will begin to unravel some of the mechanisms that nerve cells use to wire up together during development.

This project will begin to unravel some of the mechanisms that nerve cells use to wire up together during development. This information can be used to assist in trying to modulate and facilitate directed regrowth following injury.Read moreRead less

Summary
The regulation by transcription factor phosphorylation upon the myelinating process. The project will investigate the novel molecular events that control the myelinating process, which is essential for normal nervous system function. Outcomes of this project may aid the development of novel interventions to improve control of demyelinating diseases, which represent a substantial socio-economic burden.
