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.
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.
Novel Nanomaterial Solutions Based On Metal And Metal Oxide For Advanced Diagnosis Of Cardiovascular Diseases

Funding Amount
$581,037.00
Summary
Cardiovascular disease accounts of over one third of all deaths in Australia and is forecasted to become the leading cause of death in Australia and worldwide. Currently, atherosclerosis and thrombosis in coronary arteries are diagnosed by X-ray angiography, an invasive and risk-associated procedure. Our project will explore new contrast agents for the fast, reliable and safe diagnosis of cardiovascular diseases and thrombotic events, which is beneficial to many patients.
The Development Of Innovative Multiplexed Molecular Imaging Technology Targeting Improved Diagnostic Imaging Of Glioblastoma Multiforme

Funding Amount
$403,599.00
Summary
Glioblastoma Multiforme (GBM) is extremely invasive and the most lethal of all primary brain tumours. To optimise treatment planning, we propose to develop novel Multiplexed Molecular Imaging (MMI) technology employing the latest PET-MRI hybrid imaging technology. Our strategy targets the development of new F19 MRI MI agents for measuring tumour infiltration that can be multiplexed with F18 PET hypoxia tracers. Our MI agents can also act as conjugative vehicles for drug delivery.

Summary
Spinal cord injury is a devastating event that has a life-long impact on the patient’s life with wide-reaching social and economic effects. In this proposal we examine how inflammatory signals boost neuronal regeneration after injury. Furthermore, we define how new neurons are able to integrate into existing spinal circuitry. Out work provides critical insight and hold keys to unlocking strategies for future restorative therapies in the brain or spinal cord.
Brain Iron Imaging For Alzheimer’s Disease (AIBL-ADIRON Study)

Funding Amount
$1,227,885.00
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
Funder

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.
A Randomised Controlled Trial Of Low-dose Ketamine In Youth With Severe Depression And Elevated Suicide Risk

Funding Amount
$2,232,757.00
Summary
Recent research has shown that a single injection of low-dose ketamine has powerful, though short-lived, antidepressant effects. Effective treatments are urgently needed for young people with severe depression. This will be the first controlled study to test whether repeated doses of ketamine, given over 4 weeks, is effective for young patients.
The Burden Of Late Preterm Birth On Brain Development And 2 Year Outcomes – A Prospective, Longitudinal Cohort Study

Funding Amount
$838,690.00
Summary
80% of preterm babies are born from 32-36 weeks’ gestation, and are late preterm (LPT). LPT children have more learning problems, but why this occurs is unknown. This study aims to understand the effect of LPT birth on brain development. We will do brain scans at term and assess development at 2 years of age of 200 LPT and 200 full-term children. We expect LPT babies will have subtle alterations in brain development compared with term controls which will be associated with delayed development.
Caress The Detail: A Comprehensive MRI Atlas Of The In Vivo Human Brain
Funder
National Health and Medical Research Council
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.
