Neurobiology Of Relaxin-3/RXFP3 Systems: Anatomical And Functional Studies In Transgenic Mice

Summary
Mental illness is an economic and health burden worldwide, with huge costs in medical spending, lost productivity, poor quality of life for sufferers and mortality. Relaxin-3 is a peptide that acts widely within neural circuits to modulate brain activity that is altered in conditions such as anxiety and mood/sleep disorders. Our research assessing the effect of genetic removal of relaxin-3 signaling on behaviour will add to our knowledge of brain function and improve mental health outcomes.
Ascending Control Of Behavioural State And Cognition - Role Of Nucleus Incertus And Relaxin-3 Transmission
Funder
National Health and Medical Research Council
Funding Amount
$540,356.00
Summary
Mental illness and dementia are significant social and economic burdens worldwide and knowledge of their underlying causes and more effective therapies are required. Our research aims to use pre-clinical models to characterize a little studied neuronal network implicated in control of brain theta rhythm activity, which could lead to improved treatment of neuropsychiatric diseases such as anxiety and depression, and degenerative cognitive decline.
Ascending Neural Networks And Behavioural State Control

Funding Amount
$727,758.00
Summary
Our research aims to describe and understand newly identified nerve pathways or 'networks' in brain that control physiological homeostasis or balance and complex behaviours, including levels of arousal and motivation, sleep/wake patterns, learning and memory, and emotions such as fear and anxiety

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.
Molecular Mechanisms Underlying Recovery From General Anaesthesia

Funding Amount
$335,983.00
Summary
Even though general anaesthesia is an extremely common and safe procedure, doctors do not really know how it works. We have found that general anaesthetics might work in two steps, by first promoting natural sleep, and then by impairing communication between all nerve cells in the brain. It is this second step that makes surgery possible, but also makes recovery difficult – especially among patients with brain disorders. Understanding these mechanisms will promote better anaesthesia procedures.
Utilising Functional Magnetic Imaging To Predict Pre-clinical Parkinson�s Disease In Patients With Idiopathic Rapid Eye Movement Sleep Behaviour Disorder

Funding Amount
$83,712.00
Summary
In an ageing Australian population a rise in the number of people with neurodegenerative conditions, such as Parkinson's Disease (PD) is inevitable. The ability to accurately identify those people who are destined to develop such diseases, might offer a mechanism by which such progression could be aborted. This project will seek to identify a reliable method whereby cases of PD could be detected several years before they can currently be diagnosed.
Mimicking Slow Wave Sleep To Enhance Plasticity In The Elderly Human Brain

Funding Amount
$429,461.00
Summary
Cognitive and motor impairments associated with ageing have a major social and economic impact. This project will address a major driver of this decline. Brain functional decline is causally linked to poor sleep. Using non-invasive brain stimulation aspects of sleep important for maintaining cognitive and motor function will be mimicked, without the need for people to sleep. This will provide a new means to boost plasticity, and will assist in improving brain health throughout life.
Sleep Disturbance And Cholinergic Degeneration In Alzheimer's Disease
Funder
National Health and Medical Research Council
Funding Amount
$860,912.00
Summary
The largest class of drugs given to Alzheimer's disease patients aims to increase the function of cholinergic neurons that degenerate early in the disease. We will test whether disturbed sleep, which has been linked to Alzheimer's disease and cognitive decline are caused by neurodegeneration of these neurons, and whether early treatment can slow disease progression.
Discovering Deep Sleep Genes And Determining Their Roles For Preserving Cognitive Functions
Funder
National Health and Medical Research Council
Funding Amount
$484,901.00
Summary
Our mental well-being is largely tied to our sleep quality, and most cognitive disorders are also associated with poor sleep processes. Yet, we still do not know how sleep quality safeguards cognitive function. We will uncover genes that play a restorative role during deep sleep, and determine how genetic control of these deep sleep genes modulates selective attention in an animal model. Our results will suggest novel therapies for treating sleep disorders and associated diseases of the brain.

Summary
The control of neuroplasticity in the brain. This project aims to determine how neuroplasticity – the brain’s ability to remodel and make new circuits – is controlled in both excitatory and inhibitory neurons. This capacity, vital for all cognitive functions, diminishes as people age. It is imperative to determine neuroplasticity’s mechanisms and how and why they change, but it is not known how both excitatory and inhibitory neurons contribute to neuroplasticity and how these dynamic alterations ....The control of neuroplasticity in the brain.
