Summary
Traumatic brain injury (TBI) is a significant cause of mortality and morbidity in Australia, affecting approximately 21,800 Australians annually. A large number of survivors have permanent neurological deficits, causing adverse effects on lifestyle and family relationships and placing a significant burden on the health system. In this project we will address a novel means to improve TBI outcome by targeting two linked enzyme systems that together have been shown to be deleterious in this conditi ....Traumatic brain injury (TBI) is a significant cause of mortality and morbidity in Australia, affecting approximately 21,800 Australians annually.

Hypothermia Prior To Decompression For Treatment Of Acute Spinal Cord Injury

Funding Amount
$294,163.00
Summary
In spinal cord injuries, the cord is compressed as a result of vertebral injury. Urgent relief of compression improves outcome, however, is difficult because of the complexity of pre-surgical management. Our data demonstrate that hypothermia stops compressive spinal cord injury, allowing decompression to be performed in a period that will benefit most patients. This project aims to undertake the studies necessary before beginning a human trial of hypothermia prior to decompressive surgery.
Mechanisms Of PTEN Regulation By Ndfip1 And Their Biological Consequences For Neuron Survival During Brain Injury

National Health and Medical Research Council
Funding Amount
$686,640.00
Summary
We have discovered a new protein (Ndfip1) that protects brain cells from death after brain injury from trauma and stroke. We will investigate why this protein is activated only in some, but not in other, brain cells after injury. In this application, we will study the mechanisms behind neuron protection, and use this information to explore how to increase the number of brain cells activating Ndfip1.
This study investigates how much an individual's genes and environment account for the wide variation in brain structure and function. Using brain imaging we examine in what way the connectivity of the brain of identical and non-identical twins is the same or different from that of their co-twin, and carry out analysis of their DNA to identify some of the genes involved. This will provide fundamental information on genetic mechanisms influencing variation in brain structure and function.
Social Functioning In Early Primary School Following Traumatic Brain Injury Prior To Age Three: The Contribution Of Cognitive, Environmental And Neurological Factors
Funder

Funding Amount
$394,501.00
Summary
Children of preschool age and older demonstrate social problems after a traumatic brain injury (TBI). What effect a TBI has on the social function of young children (before 3 years) is currently unknown but is thought that these children have more problems than older children do. This study will look at how a TBI impacts on the social function of young children and the role of cognition and brain development in social function will also be explored.
Quantifying The Role Of Epigenetic Factors In Neurocognitive Outcomes: A Twin Study
Funder
National Health and Medical Research Council
Funding Amount
$1,516,790.00
Summary
We aim to identify the environmental factors in early life that contribute towards an individual brain development using MRI brain scans and related psychological skills measured in late childhood. We are using twins to better understand differences in their early life environments independent of genetics.
Central Nervous Pathways For The Sympathetic Control Of Immune Function
Funder

Funding Amount
$300,741.00
Summary
The nervous system regulates immune system function by a special set of nerves that are part of the sympathetic nervous system. This project aims to work out which brain pathways control them.
Understanding The Mechanisms Of Development And Treatment In Hydrocephalus.

Funding Amount
$395,914.00
Summary
This project aims to investigate the progressive change in cerebrospinal fluid dynamics, axonal damage and tissue mechanical properties during the development and treatment of hydrocephalus in-vivo. Results from this study is important to elucidate the mechanisms of hydrocephalus and to improve treatment and diagnosis of hydrocephalus.
Emotion Regulation After Brain Injury: New Approaches To Remediation
Funder
National Health and Medical Research Council
Funding Amount
$922,662.00
Summary
Traumatic brain injuries, often from motor vehicle accidents, devastate the lives of thousands of young Australians each year and can lead to changes in personality and emotional regulation. Frontal lobe damage may cause apathy, withdrawal and loss of motivation or a loss of control leading to poor inhibition and anger outbursts. In this project we trial some experimental approaches to improving emotion regulation including biofeedback, self-control therapy and direct cortical stimulation.
Genetic And Environmental Determinants Of Brain Networks In Ageing

National Health and Medical Research Council
Summary
Is brain ageing genetically or environmentally determined, or an interaction of both? We will explore the influence of genes and the environment on brain connectivity during ageing by studying how the brain network relates to cognitive functions.
