Seizures appear unpredictable and greatly affect the quality of all aspects of life for patients with epilepsy and their carers. New advances in complex systems theory suggest that transitions from normal brain activity to seizures are preceded by measurable changes in the brain’s responses to stimuli, known as critical slowing. Measurement of critical slowing will enable prediction of seizures, providing a warning system, and possibly an opportunity to deliver preventative therapies.
Circadian Mechanisms For Sex Differences In Shift Work Tolerance

Summary
It is well-established that women respond more poorly than men to shift work schedules, having more health complaints, more drowsiness and more accidents at work than men. The physiological cause of this sex difference is not known. Our research suggests that differences in the circadian rhythms of women and men may promote shift work intolerance in women. This study is designed to examine sex differences in the effect of office-level light on the biological clock during a simulated night shift.
Quantifying The Role Of Epigenetic Factors In Neurocognitive Outcomes: A Twin Study
Funder
National Health and Medical Research Council
Funding Amount
$1,516,790.00
Summary
We aim to identify the environmental factors in early life that contribute towards an individual brain development using MRI brain scans and related psychological skills measured in late childhood. We are using twins to better understand differences in their early life environments independent of genetics.
Relaxin-3/RXFP3 Signalling And Regulation Of Affective Behaviour _ Studies In Normal/transgenic Mice
Funder
National Health and Medical Research Council
Funding Amount
$578,268.00
Summary
Mental illness is a significant social and economic burden worldwide and knowledge of the underlying causes and more effective therapies are required. Our research aims to use pre-clinical animal models to characterize a little studied brain neuronal network implicated in control of arousal and stress, which could lead to improved treatment of psychiatric disorders such as depression.
A Multi-cohort Investigation Of The Effects Of BDNF Val66Met On Tau, Neurodegeneration And Cognition In Preclinical Alzheimer’s Disease
Funder
National Health and Medical Research Council
Funding Amount
$325,758.00
Summary
There are currently no disease modifying therapies for Alzheimer’s disease. We will elucidate the role of a genetic polymorphism that has previously been shown to exert neuroprotective effects on memory decline and brain volume loss associated with Alzheimer’s disease. By studying the role of this gene in multiple cohorts of individuals with varying degrees of Alzheimer’s disease risk, this study has high potential to uncover novel disease-modifying strategies for the treatment of the disease.
Characterisation Of Eurl, A Novel Gene Implicated In The Etiology Of Abnormal Brain Development And Intellectual Disability
Funder
National Health and Medical Research Council
Funding Amount
$597,541.00
Summary
Intellectual disability affects around one per cent of Australians, and can arise from genetic abnormalities during fetal life, such as through abnormal regulation of gene expression. We have identified a novel gene, known as eurl, which controls brain assembly as well as the ability of neurons to form functional connections within the brain. We will investigate how this novel gene controls brain development, and characterise eurl as a potential therapeutic target for learning and memory.
APLP2: A Neuroprotective Receptor For Acute Brain Injury

Funding Amount
$648,739.00
Summary
Traumatic brain injury (TBI) is the major cause of deaths in Australians under 45 years of age. We have shown that the amyloid precursor protein (APP) is protective in models of TBI. To understand how APP is neuroprotective we have isolated APP binding proteins and identified the amyloid precursor-like protein 2 (APLP2) molecule as a strong candidate for the APP-neuroprotective receptor. This grant will investigate the interaction between APP and APLP2 as a novel neuroprotective pathway in TBI.
Biomaterials For The Direct Reprograming Of Reactive Astrocytes Into Functional Neurons
Funder
National Health and Medical Research Council
Funding Amount
$630,500.00
Summary
We will employ peptide inspired hydrogel nanoscaffolds that can be injected into a brain lesion as a single injection to provide chemical and physical support for the surrounding cells. We will utilize various modifications to these materials to reprogram inflammatory cells into neurons, whilst also promoting the survival, maintenance and growth of existing neurons to encourage repair.
Efficacy Of A 3-month Aerobic Exercise Regime For Restoring 'brain Health' In Heavy Cannabis Users
Funder
National Health and Medical Research Council
Funding Amount
$1,209,221.00
Summary
Over a ten-year period, we, and others have documented the brain and psychological harms associated with regular cannabis use. We have now shown that these harms are not permanent, but can be restored. However, the recovery process takes a long time. This study will build on our extensive work to date and, for the first time, investigate whether a specific form of exercise will cause accelerated and beneficial changes in i) the brain and ii) the daily lives of heavy cannabis users.
Neurobiology Of Childhood Speech Disorders: Improving Detection, Diagnosis And Clinical Care
Funder
National Health and Medical Research Council
Funding Amount
$994,575.00
Summary
One in 20 children have a speech disorder at school entry, with lifelong deficits in psychosocial, academic and employment outcomes. Little is known about the aetiology of speech disorders, preventing targeted care. We combine expertise in speech pathology, gene discovery and brain imaging, to advance knowledge on gene and brain contributions to speech disorder. We will have direct impacts on clinical care including detection, diagnosis and counselling, optimising outcomes for affected children.
