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.

Summary
Stroke is a major cause of death and disability in our community. Most strokes result from a blocked blood vessel in the brain which leads to the almost immediate death of some brain tissue. However surrounding brain tissue is potentially salvageable if blood supply can be restored. This research uses magnetic resonance imaging (MRI) to better demonstrate salvageable brain tissue so that existing treatments to re-open blocked blood vessels can in future be safer and more widely applicable.
Our lives depend upon maintaining the correct body temperature. Failure to regulate it properly may be lethal. This is particularly true in the elderly, who are more susceptible on the one hand to heat stroke and on the other to hypothermia. Many die each year from both these causes. Body temperature is regulated by the brain, yet our understanding of how and where in the brain this happens is poor. This proposal aims to work out the 'wiring diagram' of brain temperature control pathways in rats ....Our lives depend upon maintaining the correct body temperature. Failure to regulate it properly may be lethal. This is particularly true in the elderly, who are more susceptible on the one hand to heat stroke and on the other to hypothermia. Many die each year from both these causes. Body temperature is regulated by the brain, yet our understanding of how and where in the brain this happens is poor. This proposal aims to work out the 'wiring diagram' of brain temperature control pathways in rats and to begin to extend this knowledge to humans. This work will generate new knowledge about a vital function. The insights obtained will inform and guide future strategies in aged care, intensive care and perioperative care.Read moreRead less
Functional Mapping Of Autonomic Control Circuits In The Human Brain

Summary
Nerves called sympathetic nerves stimulate the heart and raise blood pressure. The brain drives them when we are excited or frightened. It also over-drives them in cardiovascular diseases, and this makes matters worse. This project will use MRI brain scanning to investigate, for the first time, how the cerebral cortex and brain stem act together to control sympathetic nerves. Understanding how this system works normally will help tell us how it may malfunction, and what we can do to correct it.
I am a neuroscientist using robust statistical methods to identify effective neuroprotectants for stroke. I am examining the use of neuroprotection and novel imaging approaches to extend the utility of thrombolysis, and testing the hypothesis that neuropr
Despite advances in medical management, critical care clinicians continue to search for procedures that will improve outcomes in critically ill patients with haemorrhagic shock (a life-threatening fall in blood pressure).

Shock is a consequence of an active process triggered by the brain . The proposed research aims to elucidate the precise sequence of brain events that initiate and maintain shock. We will also evaluate the effects of interventions (designed to ameliorate or reverse shock) on the brain events that drive the shock response. The results of this research will offer, for the first time, a rational basis for devising new methods to reverse or ameliorate shock and potentially improve clinical outcomesRead moreRead less
