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.

This project aims to address the computational modelling of Auslan. The project expects to generate knowledge by creating the largest Auslan dataset, enabling further advancements in this research area. The dataset will also play an essential role in other research fields, e.g., sign linguistics. Expected outcomes include the invention of the first Auslan recogniser and generator capable of distinguishing and synthesising 1000+ signs, representing a substantial advancement towards fully automated Auslan translation. This should provide significant benefits for the Australian Deaf community, such as high-quality digital systems for education and communication, resulting in increased quality of life and inclusion in the Australian society.Read moreRead less
Social buffering of fear inhibition in adolescent rats. Adolescence is an important time when individuals learn to manage stress-related emotions like fear. Peers can help, or hinder, individuals to regulate fear. This project aims to understand how, when, and for whom social buffering of fear regulation occurs during adolescence. It uses a behavioural, pharmacological, and neural approach to explore these issues. The project aims to close the gap in understanding of how social companions affect ....Social buffering of fear inhibition in adolescent rats. Adolescence is an important time when individuals learn to manage stress-related emotions like fear. Peers can help, or hinder, individuals to regulate fear. This project aims to understand how, when, and for whom social buffering of fear regulation occurs during adolescence. It uses a behavioural, pharmacological, and neural approach to explore these issues. The project aims to close the gap in understanding of how social companions affect basic learning and memory processes in an understudied population of adolescents. The expected outcomes of this project include a richer knowledge of how peers shape emotional regulation during development, which will ultimately inform social-based approaches for improving emotion regulation in youth.

Ocular Motility In Autism And Asperger S Disorder: Dissociation Of Motor Deficits.

Funding Amount
$131,235.00
Summary
We will use ocular motor technology to investigate motor dysfunction in autism and Asperger's disorder, to advance our understanding of the neurobiological bases of these disorders. This will help clarify whether neural networks are differentially disrupted in these disorders, as our previous clinical research suggests. This dissociation and the subsequent development of an ocular motor clincal screen may improve diagnosis, and potentially treatment, of these devastating conditions.
Emerging Severe Mental Illness In Young People: Clinical Staging, Neurobiology, Prediction & Intervention From Vulnerabi

Summary
Mental disorders, such as psychotic and severe mood disorders, are the largest cause of disability in Australia. However, there is still little known about illness onset, relapse and progression. We have developed a clinical staging model with transition points from symptomfree to subthreshold status, to threshold disorder to chronic disability. We will investigate neurobiological and psychosocial factors which increase the risk of progression through these stages and use this model as a basis f ....Mental disorders, such as psychotic and severe mood disorders, are the largest cause of disability in Australia. However, there is still little known about illness onset, relapse and progression. We have developed a clinical staging model with transition points from symptomfree to subthreshold status, to threshold disorder to chronic disability. We will investigate neurobiological and psychosocial factors which increase the risk of progression through these stages and use this model as a basis for examining the effectiveness of interventions, for example to prevent, delay or ameliorate onset and relapse, and promote vocational recovery. Thus major clinical and public health benefits and an understanding of factors that contribute to the onset and progression of illness will result.Read moreRead less

Summary
While it is well known that autism and Asperger's disorder are associated with social, communicative, and behavioural symptoms, it is less well known that affected individuals also have considerable movement and coordination difficulties. For example, these children often have problems with hand writing, walking, hopping, skipping, catching, and running.

For example, these children often have problems with hand writing, walking, hopping, skipping, catching, and running. These skills are very important for success at school; for example, if children are unable to participate in school sports they often feel isolated and rejected from the peer group. Also, hand writing problems have a significant impact on children's academic performance. Our previous research has suggested that there may be particular patterns of motor problems that characterise individuals with autism and Asperger's disorder. Our proposed research aims to use the kinds of 3D motion analysis technology used in the movie industry to capture exactly how people affected by these conditions move and respond to the environment. This study will enable us to highlight particular parts of the brain-motor circuitry that are affected by these disorders and will also enable us to more clearly distinguish how autism is different from Asperger's disorder. Ultimately, it is hoped that our motor investigations will lead to improved assessment and interventions for these disorders.Read moreRead less

Funding Amount
$17,652,824.00
Summary
The team is comprised of neurologists, molecular geneticists, physiologists and brain imaging specialists and leads the world in the discovery of the genetic causes of epilepsy. They will continue to identify genes underlying epilepsy and study how genetic variations result in development of seizures. Advanced brain imaging will be used to understand the effects of genetic variation on brain structure and function. This study may lead to new diagnostic methods and treatments for epilepsy.
Defining The Epigenetic Origins Of Maternally Inherited Disease.

Summary
Epigenetic (non genetic) changes to the DNA in sperm and eggs can alter outcomes in children. Despite the potential for drugs and diet to mediate some of these inherited effects, the processes involved are very poorly understood. By determining the mechanisms that regulate epigenetic inheritance, this project will improve our understanding of how epigenetic mechanisms acting in the parent, can mediate inherited disease and life-long health outcomes in our children.
Prevalence report by the Australian Advisory Board on Autism Spectrum Disorders (ASD) estimated that 1 child in every 160 children in the 6-12 year-old age group is affected by ASD. There is no cure for ASD and the causes are not understood. We propose that sex hormones may play a role in the development of these disorders. We will test this hypothesis using knockout and transgenic mouse models which have social interaction deficits and brain structure reminiscent of these disorders.
