Summary
Excessive anxiety is disabling, such that people who suffer from a clinical anxiety disorder are often crippled by overwhelming emotional and physical symptoms. We will use sophisticated brain imaging technology to understand how certain brain areas produce feelings of anxiety, including a common fear of arousal related bodily sensations. This work is expected to enhance our basic understanding of the brain basis of anxiety symptoms and may inform new treatment options with biological rationale.
Light, Sound And Touch Influence The Autonomic Nervous System Via A Non-canonical Pathway

Funding Amount
$329,666.00
Summary
We examine a recently discovered brain circuit through which visual and acoustic stimuli can interact with the neural systems that control breathing, blood pressure and heart rate. The outcomes of this project will characterise a pathway by which the external environment can interrupt the normal activity of systems vital for health and wellbeing independent of cognition.
Clarifying The Pathogenic Role Of Arousal-hyperventilation In Obstructive And Central Sleep Apnoea: Testing Fundamental Pathophysiological Mechanisms And A Strategic New Treatment

Funding Amount
$414,717.00
Summary
This project is designed to understand the mechanisms underpinning much more stable breathing during deep sleep in obstructive sleep apnoea (OSA). A newly developed analytical technique will be used to examine breathing effort changes across sleep, and interactions with respiratory-induced awakenings in OSA patients. In addition, a new treatment designed to stabilise breathing will be tested and refined towards a new treatment option for OSA and for central sleep apnoea.
The Role Of Arousal In The Pathogenesis Of Obstructive Sleep Apnea And Implications For Novel Therapeutic Treatments

Funding Amount
$297,888.00
Summary
This research forms part of a series of studies aimed at characterizing the relative importance of the various physiological causes (phenotypes) of obstructive sleep apnea (OSA) and has the potential to lead to individually tailored novel therapies according to these traits. Specifically, this proposed research will investigate the role of arousal from sleep (brief awakening) in OSA and explore methods of manipulating the arousal threshold as a new treatment approach for certain OSA patients.
