Summary
I committed to understanding of how the brain develops, grows and regenerates. My laboratory is active in finding a cure for brain injury following brain trauma or brain ischemia. I have discovered that the genes that drive neuron migration and wiring in the fetus also function in the adult brain to improve neuron survival and regeneration. Probing the function of these genes will deliver twin benefits in preventing brain disorder in the newborn and treating brain disease in the adult.
Prof Alan Connelly is an internationally recognised neuroimaging researcher specialising in MRI. His major areas of research are in the development of new methods to acquire and process MR images of both structural and functional aspects of the brain, and the application of these novel methods to clinical neuroscience problems. His work has had a major impact in the field of epilepsy, where techniques that he pioneered have been widely adopted in specialist epilepsy centres worldwide.
Development of normal brain function requires information transfer and integration from outside and within the brain. Normal brain wiring is guided by genetic and environmental cues, whose relative contributions remain controversial. This project investigates the physiological and behavioural consequences of abnormal brain wiring, and the potential for controlled environments and targeted interventions to overcome the deficits. Relevance includes neurotrauma as well as mental illnesses.
The mammalian cerebral cortex is an area of the brain responsible for all higher order cognitive processes. I investigate how connections from between the two cerebral hemispheres during embryonic and foetal development, thus enabling the brain to coordinate information from the two sides of the body. Malformations of these connections cause mental retardation and sensory and motor deficits. I want to understand how these brain defects occur and how best to treat them.
Imaging Atlases Of The Brain Of Humans And Experimental Animals

Summary
This project uses imaging techniques and molecular genetics to produce the next generation of brain maps. It will advance our understanding of the organisation and structure of the brain and spinal cord of humans and experimental animals – paving the way for the development of psychotherapeutic drugs and more accurate interventions on the human brain. The new maps will help those who study the brain of patients with diseases such as Alzheimer’s or Parkinson’s or animal models of these diseases.
Oxidative Processes In Vascular Health And Disease

Summary
The process that turns cut fruit brown when it is exposed to air is thought to cause disease of our blood vessels and heart as we age. Despite what we first thought, 'blocking' this oxidation process with antioxidant supplements does not lower heart disease. This is because oxidation not only causes harm but also is useful and essential for normal body function. Our research program aims to show which oxidative processes are needed for blood vessel health or cause vessel disease.
Pathophysiology And Treatment Of Malaria In Our Region

Summary
Malaria continues to kill 420,000 people/year. I will lead a team of clinical scientists in identifying how each of the different malaria parasites cause damage to small blood vessels, kidneys and other organs, and will test whether two different drugs can improve these processes and reduce illness. Many of my previous research findings have changed malaria treatment in Australia and across SE Asia, and, where appropriate, I will use new research findings to improve treatments.

Summary
This project uses imaging techniques to produce the next generation of maps of the central nervous system. It will advance our understanding of the organisation and structure of the brain and spinal cord of humans and experimental animals, paving the way for the development of psychotherapeutic drugs and more accurate interventions on the human brain. The new maps will help those who study the brain of patients with diseases such as Alzheimer’s, Parkinson’s or animal models of these diseases.
Normal And Abnormal Development Of Brain Wiring And Its Impact On Brain Function

Funding Amount

Summary
My laboratory is striving to understand how the patterns of neuronal connections form in the developing brain and how these underpin the functions of the brain throughout life. We use high-field magnetic resonance imaging to measure brain wiring and we investigate the genetic and environmental mechanisms causing developmental brain disorders that result in intellectual disability, autism, epilepsy and some mental illnesses.
Heart failure (HF) describes where the heart cannot pump adequately to meet the bodyÍs needs. Mortality remains high; therefore, there is an urgent need for new treatment approaches. The present grant aims to: (1) evaluate treatments for patients at high-risk for future development of HF (2) examine the ability to safely withdraw unnecessary HF drugs (3) focus on the effect of HF on the kidney via novel treatment strategies (4) examine the emerging role of cancer drugs in development of HF.
