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.
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.
Understanding And Preventing Adverse Developmental Effects Of Perinatal Infection/inflammation

Summary
Exposure of babies to infection or inflammation within the womb is common and is associated with preterm delivery and illness in newborns. The biggest problem for these babies is lung disease due to inflammation of the lungs before birth and/or in response to lung injury after birth. We are investigating how inflammation alters lung development, and working on developing a novel cell therapy to prevent life-threatening newborn lung disease.
3D Histological And MRI Atlases Of Brain And Spinal Cord For Research And Clinical Practice

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
$763,845.00
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.
Understanding The Impact Of Preterm Birth On Development: Improving Outcomes For Preterm Infants.

Funding Amount

Summary
Approximately 10% of babies are born prematurely and many suffer long-term health problems. Our aim is to understand how premature birth affects the development of the cardiovascular, respiratory and central nervous systems. This understanding will help to improve the long-term health outcomes for premature infants. By working with medical practitioners treating premature babies we are well placed to translate our findings on preventing and treating developmental injury into clinical practice.

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.
Whether we are born as a male or a female affects our sense of social place, behaviour, gender identity, reproductive options, and disease susceptibility. I am a molecular geneticist investigating the biology of gender. I study the mechanisms underpinning sexual development, with an emphasis on identifying the genetic causes of ‘intersex’ and transsex disorders. I am also studying how SRY, a male gene, controls voluntary movement, and its possible link to Parkinson’s disease.
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.
