Benefits of blood pressure lowering to combat cardiovascular disease. Stroke and heart attack are the commonest causes of death and adult disability. In Australia, approximately 50,000 people die from cardiovascular disease each year. This project will attempt to prevent stroke/heart attack and to improve quality of life by exploring better management of high blood pressure.

Summary
This project will investigate how the human brain processes a number of important aspects of human jaw muscle pain that are clinically relevant but poorly understood. For example, we do not understand why jaw muscle pain has such different behavioural effects to skin pain. Jaw muscle pain is associated with a significant emotional component not seen in with skin pains. Also, skin pain usually has a sharp or burning quality, is well-localized and is readily treated, while jaw muscle pain is a dee ....This project will investigate how the human brain processes a number of important aspects of human jaw muscle pain that are clinically relevant but poorly understood. For example, we do not understand why jaw muscle pain has such different behavioural effects to skin pain. Jaw muscle pain is associated with a significant emotional component not seen in with skin pains. Also, skin pain usually has a sharp or burning quality, is well-localized and is readily treated, while jaw muscle pain is a deep pain that has a dull, aching quality that may be referred to related sites of the face, head and neck. It is also not known why jaw muscle pain is more common in females in comparison to males. Chronic jaw muscle pain is a major symptom of patients with Temporomandibular Disorders, the most common form of non-dental orofacial pain and that involves pain in or about the jaw joint and-or jaw muscles, and often limitation of jaw movement. Chronic jaw muscle pain can have a severe effect on quality of life but its diagnosis and management is difficult. Despite the widespread prevalence of chronic orofacial pains, we have little information on the central processing of chronic human orofacial pain. This proposal will improve our fundamental understanding of how jaw muscle pain is processed in the brain. The way that the central nervous system processes and represents jaw muscle pain will help explain why these pains present differently in the clinic and should provide important information on the differences between females and males in the representation of jaw muscle pain. This information on the central processing of chronic orofacial pain is crucial to inform the direction of novel or specific management strategies. Our long-term goal is to improve the diagnosis and management of patients with Temporomandibular Disorders, and the present application represents a major new direction of research.Read moreRead less

Summary
A flexible high throughput analytical system for psychopharmacology and drug discovery. A sensitive new liquid chromatography mass spectrometer will enable a team of leading researchers to detect drugs of abuse and therapeutic drugs in the brain and body as well as levels of hormones, peptides and neurotransmitters. This will enhance a large number of projects examining new treatments for addictive disorders and mental illness.
Non-invasive prediction of adverse neural events using brain wave activity. This project aims to develop intelligent decision-making systems for non-invasive identification of adverse neural events (fatigue/freezing of gait) through real-time monitoring of brain wave activity.

This project aims to develop intelligent decision-making systems for non-invasive identification of adverse neural events (fatigue/freezing of gait) through real-time monitoring of brain wave activity. Analyses of the effectiveness of the changes in physiological parameters associated with electroencephalography (EEG) signals, advanced biomedical instrumentation, and optimal computational intelligence will form a basis for the development of platform technology capable of monitoring and detection of neural health status. Success is expected to yield a new generation of smart dynamic non-invasive systems that will be critical for developing effective solutions to counter life threating conditions for a large cross section of the Australian population.Read moreRead less
Assessment of circadian and light interactions in adolescent sleepiness. This project aims to examine the relative contributions of multiple biological clock and sleep factors that may be linked to cognitive function and sleepiness in adolescents. Over 70 per cent of adolescents in Australia experience insufficient sleep. Cross-sectional studies have shown that insufficient sleep and mistimed sleep lead to reduced cognitive function. The project intends to identify specific sleep and circadian m ....Assessment of circadian and light interactions in adolescent sleepiness. This project aims to examine the relative contributions of multiple biological clock and sleep factors that may be linked to cognitive function and sleepiness in adolescents. Over 70 per cent of adolescents in Australia experience insufficient sleep. Cross-sectional studies have shown that insufficient sleep and mistimed sleep lead to reduced cognitive function. The project intends to identify specific sleep and circadian markers that are linked to academic performance, and generate innovative algorithms that predict these associations. The project will provide new knowledge to drive prevention and early intervention programs that use sleep-wake and light exposure information to improve sleep quality.Read moreRead less

Summary
Nanolamps: unlocking targeted gene silencing in deep tissue with nanoparticle-based light sources. In order to better understand the function of genes, this project will develop a new method of tightly targeted gene silencing deep inside of the body by nanoscale light sources. This will shed new light on the nervous system and, in the first instance, help to elucidate the role of the PACAP neurons in blood pressure regulation.

Functional analysis of long noncoding RNAs expressed in the brain. For many years, the mammalian genome has been thought to be mainly junk. Recently, however, it has become evident that most of the genome specifies RNAs that do not encode proteins ('long noncoding' RNAs, lncRNAs), many of which are brain-specific. This project aims to determine the functions of lncRNAs that are expressed in the hippocampus (involved in learning) and the cerebellum (involved in movement coordination) by deleting ....Functional analysis of long noncoding RNAs expressed in the brain.

Recently, however, it has become evident that most of the genome specifies RNAs that do not encode proteins ('long noncoding' RNAs, lncRNAs), many of which are brain-specific. This project aims to determine the functions of lncRNAs that are expressed in the hippocampus (involved in learning) and the cerebellum (involved in movement coordination) by deleting them in mice, testing for developmental, cognitive and motor effects, and characterising the structures with which they are associated. The results of the project are expected to open new vistas in neuroscience, contributing to understanding the molecular basis of brain function and the 'dark matter' of the genome.Read moreRead less

Summary
Alzheimer’s disease (AD) begins many years before diagnosis and yet its aetiology is still poorly understood. The BRIDGET consortium aims to identify genetic variants that are associated with structural brain ageing, cognitive performance, and dementia risk in richly phenotyped international and Australian population-based samples. This work aims to provide crucial information on the molecular pathways leading to AD, potentially leading to improved health outcomes for our ageing population.
