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.
Brain Iron Imaging For Alzheimer’s Disease (AIBL-ADIRON Study)

Summary
Iron accumulation in the brain is linked to Alzheimer's disease. New Magnetic Resonance Imaging scans allow us to painlessly image the brain and measure its size and iron concentration. In this project more than 330 volunteers over 60 will be scanned every 18 months over 3 years. We will determine if those subjects with higher iron concentration in their brain have a smaller brain and worse performance in this period. This will confirm a role for iron in Alzheimer's as a new treatment target.
A 3D Cross-Modality Atlas Of The Human Brainstem For Scientists And Clinicians

Funding Amount
$363,455.00
Summary
Recent technical advances dramatically improved imaging of the human brainstem. However, there are limited frameworks for interpreting the images. The project will address this by acquiring high quality MRI anatomical and MR microscopy data from postmortem brains and registering these with structures in Atlas of the Human Brainstem (Paxinos and Huang, 1995) where almost 500 brain areas are delineated. Our work will assist with the diagnosis of brain disorders and facilitate clinical research.
Novel Methods To Study Structural-functional Connectivity In Epilepsy And Schizophrenia

Summary
Magnetic Resonance Imaging (MRI) is a non-invasive method that has revolutionised our understanding of clinical neuroscience. MRI provides not only high-contrast anatomical images, but also information on brain physiology and function. My primary goal is to develop and optimise novel MRI methods for a more accurate measure of brain structure and function. My research program will focus on the application of these methods to the investigation of epilepsy and schizophrenia.
Stroke is a major cause of death and disability in adult across the world. Understanding how exactly brain cells are affected in stroke and how they are injured, and how they response to treatment is important in order to develop new treatment to maximize recovery and minimize brain injury after stroke. This project uses advanced MRI being performed at several time points after a stroke to study how the brain tissues recovers or dies after a stroke.
Caress The Detail: A Comprehensive MRI Atlas Of The In Vivo Human Brain

Funding Amount
$461,978.00
Summary
This project will construct a detailed MRI atlas of the living human brain. The atlas will be online and compatible with tablet computers to provide a convenient, powerful reference tool for researchers and clinicians. It is a collaboration between George Paxinos, a leader in brain cartography, and Mark Schira, an emerging scientist in MRI technology. They will use high resolution in vivo MR images obtained at the University of Queensland Centre for Advanced Imaging.
Imaging Of Acute Ischemic Stroke – Improving Patient Selection For Thrombolysis

Summary
Stroke is a major cause of death and disability in our community and is most often due to a blocked blood vessel. Powerful treatments are available to open blocked blood vessels but there are restrictions on eligibility and some risks. This research aims to improve doctors' understanding of stroke in the individual patient to aid treatment decisions by identifying those with potentially salvageable brain tissue and avoiding those with high risk of bleeding complications.
Pain has a detrimental impact on ones quality of life and a significant financial impact on the community. Although some of the pathways that code pain in the brain have been defined, it was recently proposed that there also exists a pain-specific pathway in humans. Using human brain imaging, we aim to determine if such a pathway exists and if it is altered in subjects with chronic pain. The existence of such a pathway would significantly aid in the development of better treatment regimes.
Brain Connectivity Biomarkers Predict Specific Memory Consolidation Deficits Across Dementia Subtypes

Funding Amount
$83,149.00
Summary
With the increasing ageing population there is expected to be a significant increase in the number of dementia cases in the near future. This project aims to improve the accuracy of existing diagnostic protocols for dementia by combining recent advances in magnetic resonance imaging with traditional cognitive assessments. We expect the outcome to improve detection in the early stages of disease onset so that patients may receive immediate medical treatment.
Is Stroke Neurodegenerative? A Longitudinal Study Of Changes In Brain Volume And Cognition Following Stroke

Funding Amount
$1,044,837.00
Summary
There is no direct evidence linking Alzheimer’s Disease (AD) and stroke. It is unknown whether stroke can trigger progressive dementia in the same way as AD. In a group of stroke patients, we will measure MRI brain volume and cognition in the 5 years after stroke. These findings will be critical for identification of those patients most at risk of dementia after stroke. This will allow future early intervention for these patients, via promising AD disease-modifying therapies.
