Summary
We will employ peptide inspired hydrogel nanoscaffolds that can be injected into a brain lesion as a single injection to provide chemical and physical support for the surrounding cells. We will utilize various modifications to these materials to reprogram inflammatory cells into neurons, whilst also promoting the survival, maintenance and growth of existing neurons to encourage repair.

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.
The processing of sensory information within cortical circuits. This project aims to improve our knowledge of neuronal activity during sensory perception and therefore shed light on overall brain function during behaviour. Understanding how dendrites receive and process this information is crucial to understanding brain function during sensory processing and perception.

This project aims to improve our knowledge of neuronal activity during sensory perception and therefore shed light on overall brain function during behaviour. Understanding how dendrites receive and process this information is crucial to understanding brain function during sensory processing and perception. This proposal aims to characterise dendritic activity during sensory input and discover how this activity contributes to behavioural tasks. In particular, the project plans to investigate activity of different dendritic domains during sensory perception and sensory-based behaviour. The project seeks to improve our knowledge of the importance of dendrites in transforming information from the sensory environment and highlight the cellular and network mechanisms contributing to behaviour.Read moreRead less
The central nucleus of the amygdala and alcohol-seeking behaviour. Alcohol abuse and alcoholism is a significant problem in Australia (and throughout the world). However, pharmacological interventions remain limited due to our poor understanding of the neural networks underlying addictive processes. These experiments will explain how the positive rewarding and negative reinforcing aspects of alcohol are transduced within the brain. We believe that our research will facilitate the ability to trea ....The central nucleus of the amygdala and alcohol-seeking behaviour. Alcohol abuse and alcoholism is a significant problem in Australia (and throughout the world). However, pharmacological interventions remain limited due to our poor understanding of the neural networks underlying addictive processes. These experiments will explain how the positive rewarding and negative reinforcing aspects of alcohol are transduced within the brain. We believe that our research will facilitate the ability to treat alcoholism at a pharmacological level, enabling the continuation of abstinence or the prevention of relapse, while allowing other factors such as social support structure and coping skills to be developed for each individual, with flow-on social and economic benefits for society as a whole.

Summary
This research aims to develop a procedure that allows for the safe and effective use of stem cells as a therapy for Parkinson’s disease. It is based on the concept that new dopamine neurons, generated from stem cells, can be implanted into the brain of the patients in order to replace those lost to the disease, thereby improving motor function.
Subcellular recruitment of a RhoA ubiquitination complex by Rnd proteins. This study addresses a novel molecular mechanism through which members of the Rnd family of GTP-binding proteins regulate the morphology and migration of immature nerve cells of the developing nervous system. This study has broad implications for the understanding of cell migration during embryo development, as well as in health and disease.
Gene-environment interactions mediating experience-dependent plasticity in the healthy and diseased brain. The aim of this project is to understand how genes and environment combine to affect susceptibility to various brain disorders, using models of human diseases and manipulating environmental factors such as mental and physical activity. The project's focus is on neurological and psychiatric disorders, including Huntington's disease, depression, schizophrenia and autism.
Exploring Scanning Ultrasound (SUS), A Novel Method To Treat And Prevent Neurodegenerative Disease

Funding Amount

Summary
We developed a novel scanning ultrasound (SUS) protocol that clears toxic protein aggregates and restores memory function in mouse models of Alzheimer's disease (AD), without the need for therapeutic agents. Here we aim to determine whether SUS has preventative potential, whether there are synergistic effects, and whether a therapeutic antibody combined with SUS leads to an enhanced therapeutic outcome. Together this will guide the development of an ultrasound therapy in AD patients.
Modelling the human nervous system with human pluripotent stem cells. The human nervous system is one of the most complex structures evolved to date. In order to understand how it functions, and dysfunctions in a diseased state, it is fundamental to decipher how it develops to generate various neuronal populations that form this elaborate network. Human stem cells provide a valuable source to study such processes. The aim of this project is to use human stem cells to study how early progenitor c ....Modelling the human nervous system with human pluripotent stem cells. The human nervous system is one of the most complex structures evolved to date. In order to understand how it functions, and dysfunctions in a diseased state, it is fundamental to decipher how it develops to generate various neuronal populations that form this elaborate network. Human stem cells provide a valuable source to study such processes. The aim of this project is to use human stem cells to study how early progenitor cell types that structure the nervous system are generated and how their neuronal derivatives form connectivity and functional synapses. The outcome of these studies is that we will establish a cellular model of human neurogenesis that can be utilised to study developmental disease processes.Read moreRead less

This project will study the effects of different housing conditions on neuroplasticity-related cognitive function by combining an innovative operant conditioning behavioural test (computerised touch-screen technology) and new molecular approaches. Potential gene-environment interactions will be revealed using genetically targeted mice which have never been assessed in that context (mutants with altered glucocorticoid and serotonin signalling). This project will study whether specific stages of the neuroplasticity process are differentially modulated through gene-environment interactions, ultimately resulting in changes to behaviour and cognitive functions. This will lead to a better understanding of the potential approaches that could be used to improve cognitive function.Read moreRead less
