Mechanisms Of PTEN Regulation By Ndfip1 And Their Biological Consequences For Neuron Survival During Brain Injury
Funder

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.
Emotion Regulation After Brain Injury: New Approaches To Remediation

$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.
Understanding White Matter Injury In Term-born Children With Cerebral Palsy

Funding Amount
$193,863.00
Summary
The type of brain injury in cerebral palsy varies. In some children the brain develops abnormally in early pregnancy; others have a stroke or suffer from lack of oxygen around the time of birth. Little is known about the group of children born at term who have damage to the brain’s white matter, a pattern more typical of premature birth. This project will explore brain imaging, potential risk factors, and clinical outcomes for these children to identify possible causes and prevention pathways.
Social Functioning In Early Primary School Following Traumatic Brain Injury Prior To Age Three: The Contribution Of Cognitive, Environmental And Neurological Factors

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.
Sensory Cortex Processing Changes Underlying Brain And Behaviour Deficits Caused By Traumatic Brain Injury

Funding Amount
$576,795.00
Summary
Traumatic brain injury (TBI) from physical head trauma causes behavior and cognitive deficits. The burden for victims, families and the community is enormous: total life-time expenses in moderate-to-severe TBI are estimated to be $8.6 billion in Australia. We aim to elucidate whether changes in how the brain processes sensory information could underlie TBI-induced deficits in complex behaviour and whether these changes will be ameliorated by the three currently-most-promising treatments for TBI.
Functional Neurogenesis In The Injured Neocortex Of The Nonhuman Primate

Funding Amount
$966,048.00
Summary
Research over the past couple of decades has revolutionised our understanding of the capacity of the brain to generate new cells, especially following an injury. However, what does remain controversial is whether this phenomenon occurs in all areas of the brain, especially following a severe traumatic brain injury or stroke. This project will examine whether the outer surface of the brain has the potential to generate new cells following a brain injury and whether they become functional.
The Involvement Of The Kynurenine Pathway In Blood Brain Barrier Disruption And Its Relevance For Neuroinflammatory Diseases

Funding Amount
$597,797.00
Summary
We aim to study the involvement of molecules deriving from the degradation of the essential amino acid tryptophan on the breakdown of the ñblood-brain barrierî (the cellular wall separating blood and brain) that is observed in several major brain diseases. Using specific drugs blocking the production or the effects of these toxic compounds we expect to be able to preserve the integrity of the blood brain barrier and so to limit brain inflammation and neuronal loss.
Creatine Supplementation During Pregnancy As A Means Of Improving Outcomes From Preterm Birth.

Funding Amount
$479,085.00
Summary
Preterm birth results in significant health problems for babies, especially males who are more likely to die. We have shown that creatine added to the mother’s diet protects the fetus against damage caused by oxygen lack at the end of pregnancy. We will now determine if creatine can benefit babies born prematurely. We have an established model of preterm birth in lambs in which we will address these issues, and expect to show that creatine improves survival and the health of the preterm neonate.
DEVELOPMENT OF FOLDING IN THE FETAL CEREBRAL CORTEX – IDENTIFYING FUNDAMENTAL MECHANISMS AND THEIR SUSCEPTIBILITY TO DISRUPTION IN NORMAL AND ABNORMAL PREGNANCY

Summary
During pregnancy, the surface of the fetal brain gradually develops the ridges, valleys, and folds that are the characteristic feature of our highly developed brain. However, this process can be disturbed if birth occurs prematurely, the unborn baby suffers oxygen starvation in the uterus, or the mother consumes alcohol. In this project we are determining how cell migration results in the development of brain surface folding, and how hypoxia and maternal alcohol consumption affect these importan ....During pregnancy, the surface of the fetal brain gradually develops the ridges, valleys, and folds that are the characteristic feature of our highly developed brain.

Wernicke-Korsakoff syndrome is a common and frequently undiagnosed neurological disease due to thiamine deficiency. The condition leads to cognitive and neurological disability and mostly affects people with alcohol dependence. Wernicke-Korsakoff syndrome is eminently treatable with thiamine, although we have insufficient knowledge regarding the best dose of thiamine to treat the condition.
