Maternal Immune Activation And Adolescent Exposure To Cannabis In Rodents: Do Two Developmental “hits” Lead To Schizophrenia-like Changes In Brain And Behaviour?

Summary
The cause of schizophrenia most likely lies in early brain development due to either genetics or adverse environments. We will examine two successive environmental ‘hits’ in a rat model: infection during pregnancy followed by early adolescent cannabis use. We will track changes in the brain that occur in late adolescence and in young adults. We will also assess behaviour and brain function in adulthood to see if the animals exhibit patterns that mimic those that we see in schizophrenia.
The Effects Of Maternal Infection On Glutamate-related Behavioural, Electrophysiological And Neuropathological Measures Relevant To Schizophrenia

Summary
There are two well known facts about schizophrenia: maternal infection increases the risk of a schizophrenia diagnosis in adulthood and certain drugs, such as PCP, that affect particular brain chemicals induce symptoms and brain changes in healthy individuals that are similar to schizophrenia. Here we bring these two facts together by attempting to develop a maternal infection model in rodents that mimics the brain changes seen in schizophrenia, thus opening up new options for treatment.
Impaired Anticipation Of Sensory Events In Schizophrenia.

Summary
Schizophrenia is a mental illness that costs Australia millions of dollars and hundreds of lives every year. To address this we need to understand more about how schizophrenia develops. A brain measure (mismatch negativity) tracks biological brain changes and functional impairments in daily living that emerge in schizophrenia. It is not yet known if this measure can teach us about vulnerability to developing schizophrenia or only the effect of the disease. This study will address this question.
The Impact Of Faulty Relevance Filtering In Schizophrenia.

Summary
In schizophrenia ability to maintaining focused attention is impaired. We explore how problems in “next state” prediction contribute to problems in attention. The brain constantly predicts what state of activation it will be in next. When events match these predictions we can easily ignore them but if predictions are wrong a prediction–error can trigger attention interruptions. We will test whether problems in prediction-errors make persons with schizophrenia more susceptible to distraction.
Optimising And Applying Ocular Vestibulat Evoked Myogenic Potentials (oVEMPs)

Summary
This project seeks to optimise techniques for a new method of assessing the balance organs (vestibular organs) and then apply these techniques. Three conditions will be studied: vestibular neuritis - a condition causing acute and severe dizziness; Parkinson's disease, in which disorders of balance are common and superior canal dehiscence (SCD) in which there is a hole in the bone overlying one of the semicircular canals, leading to sensitivity to sound.
Measurement Of Residual Nervous System Function After Spinal Cord Injury

Summary
Multiple serial physiological recording techniques will be used to assess sensory and motor function for 12 months after spinal cord injury. This detailed information will provide, for the first time, an insight into the changes, both beneficial and deleterious, in the sensory and motor systems over time. Such information may enable changes in the management of people with spinal cord injury to prevent deleterious effects on the nervous system and enhance function.
Limbic Maturational Changes In Adolescence And Young Adulthood (LIMCA) - A Longitudinal Study

Summary
Structural and cognitive changes of the limbic regions have been linked to number psychiatric disorders. A thorough understanding of the dynamics of healthy maturation of these brain areas with age is necessary. The main aim of this research is to longitudinally study and model the neuro-developmental changes of the limbic region during adolescence and young adulthood. These will provide an invaluable template in identifying deviant patterns of limbic development in children with neuropsychiatri ....Structural and cognitive changes of the limbic regions have been linked to number psychiatric disorders.

The Role Of Redox-related Post-translational Changes Of Complement Factor H (CFH) In Age-related Macular Degeneration

Summary
Patients with AMD experience loss of central vision and this disorder is the leading cause of blindness in those aged over 50 years in Australia. There are currently no effective treatments for dry AMD. We have identified a protein that undergoes a modification in the blood and the eyes of humans with AMD that has given us new insights into how AMD develops. Specific therapies targeting this modified protein may offer a new treatment for this important cause of blindness.
Complete Genomics For Mechanistic Insight And Precision Treatments Of Schizophrenia

Funding Amount

Summary
This research project will utilise recent developments in genomic technology to make detailed high-resolution genetic maps of individuals with psychotic illness. Where conventional gene discovery approaches focus on differences at the population level, this project will integrate the variation within individuals to determine the network architecture. This will be used to generate genetic profiles for personalised medicine and provide the basis for treatments that are tailored to individuals.
The Role Of Reduced Phagocytosis In The Pathogenesis Of Age-related Macular Degeneration

Summary
Understanding the underlying mechanisms which lead to age-related macular degeneration (AMD) is critical if we are to ultimately develop novel treatments. We hypothesise that there is a defective ability to remove debris that accumulates in the retina as we age and this is a crucial step in the development of AMD. We will investigate this hypothesis in an AMD cohort and in a pre-clinical model where we will test the efficacy of an intervention that improves the ability to clear debris.
