Summary
Traumatic brain injuries (TBIs) are a common cause of brain damage, leading to a variety of disabling cognitive problems. This study will evaluate the ability of new brain imaging techniques and cognitive tests to detect previously undiagnosed brain damage and to predict patient outcome following TBI in order to improve the health care and treatment of these patients. It will also examine the contribution of other factors (eg. injury type, age, pre-injury cognitive ability) to outcome.
Development Of A Magnetic Resonance Imaging (MRI) Platform To Evaluate Neuroprotective And Regenerative Therapies In MS

Summary
Multiple Sclerosis (MS) involves inflammation and damage to nerve cells. New therapies are needed to minimize and reverse nerve cell damage. Currently, ways to judge the benefit of these therapies are primitive. We propose that assessing the benefits of these treatments in optic neuritis (inflammation of the eye nerve) is the way forward but first, we need to develop reliable tests to measure these treatments. This application proposes to use magnetic resonance imaging (MRI) for this purpose.
Neurocognitive Correlates Of Transition From Ultra-high Risk Mental State To Schizophrenia

Summary
Understanding the changes in the brains of young people when they are developing a severe mental illness is the objective of this research. State-of-the-art brain imaging and brain function data will be prospectively collected from more than 500 young people considered at ultra high risk of developing schizophrenia, the most severe of mental illnesses for which no cure exists. We aim to identify early brain changes in schizophrenia, thus allowing for more effective early intervention.
My aim is to use advanced Neuroimaging to further our understanding of the pathophysiology of brain disorders, in particular Epilepsy, but also Sleep disorders, Schizophrenia, the Dementias. In the case of my main research interest (Epilepsy) it is to red
Improving Human FMRI Through Modeling And Imaging Microvascular Dynamics

Summary
In this project we aim to establish a reliable vascular baseline to improve mapping of both small-scale functional architecture and large-scale brain networks in functional human brain mapping using MRI. By mapping the grey matter vasculature with high detail in both humans and animals, and by computing and matching of these atlases across species we will be able to validate this approach in vivo to confirm the better spatial specificity of the newly developed approach.

Brain surgery for the treatment of epilepsy is associated with a risk of cognitive impairment. Avoidance of disabling post-operative impairments depends in large measure on our ability to predict and measure individual patterns of language lateralization prior to neurosurgical intervention. Typical patterns of lateralisation cannot be assumed in patients with epileptogenic lesions. There appears to be a consensus that atypical representation is more frequent in patients with epilepsy than it is ....Brain surgery for the treatment of epilepsy is associated with a risk of cognitive impairment. Avoidance of disabling post-operative impairments depends in large measure on our ability to predict and measure individual patterns of language lateralization prior to neurosurgical intervention. Typical patterns of lateralisation cannot be assumed in patients with epileptogenic lesions. There appears to be a consensus that atypical representation is more frequent in patients with epilepsy than it is in the normal population, and values above 20% are not unrepresentative Partial epilepsy arises from a region in the brain and spreads to involve other areas. This is contrasted with generalised epilepsy, which appears to arise all over the brain simultaneously. Partial epilepsy is often associated with lesions such as tumors or hippocampal sclerosis, and often seizures are intractable. Patients with partial epilepsy have a number of sources of brain damage in the language areas. Primary brain changes may be pre-existing, which means they pre-date the onset of habitual seizures. They may consist of a focal developmental abnormality (a malformation of cortical development) or may represent a general genetic predisposition to seizures. Therefore, partial epilepsy is not only associated with severe abnormalities in epileptogenic region but also with additional widespread abnormalities in both hemispheres. There is also evidence for a correlation of abnormalities with seizure frequency with some suggestion that the duration of epilepsy may also increase the degree of abnormality in the hemisphere. The neuronal conditions in language cortex that give rise to altered lateralisation in function are currently not known. The primary aim of this study is to understand reorganisation of the language system in epilepsy by using the current most sensitive non-invasive methods of assessing brain damage and brain function, using magnetic resonance imaging.Read moreRead less
Molecular Imaging Of Brain Tumour Therapeutic Efficacy

Funding Amount
$412,200.00
Summary
The prognosis for malignant brain tumour patients that do not respond to intial treatment strategies is very poor. The fact that many of these patients patients will not survive longer than 12 months post diagnosis underscores the need to make treatment management decisions in a timely manner. This project seeks to develop and validate non-invasive early molecular imaging biomarkers that can quantify treatment efficacy months before traditional measures of efficacy are valid.
A Device For Simultaneous Continuous Acquisition Of EEG And MRI

Funding Amount
$179,401.00
Summary
We aim to further develop a world-leading method we invented that facilitates the simultaneous, continuous acquisition of the electroencephalogram (EEG - electrical brain waves measured at the scalp) and functional Magnetic Resonance Imaging (fMRI - images the location of brain activity throughout the brain). Combining the two permits non-invasive imaging of human brain function with the exquisite temporal resolution of EEG and the high spatial resolution and brain coverage afforded by fMRI.
We have previously made the most widely used animal brain atlas in the world. This atlas based on stained histological sections of the rat brain. In recent years, advances in MRI have made it possible to generate images of the rat brain at very high resolution. We have obtained a very high quality MRI image set from colleagues in Duke University in the USA, and we have begun to map these images in great detail, using our histological atlas as a guide.
