Summary
This research will develop improved electrodes for interfacing neural tissue by combining the expertise of materials scientists and electrophysiologists with medical bionics researchers. This work is expected to deliver improved bionic devices to the clinic in order to treat a variety of disorders from blindness to the control of motor tremor in Parkinson's disease.
Optimising Respiratory Care Of The Preterm Infant Using Regional Volumetric Strategies

Funding Amount
$282,086.00
Summary
Preterm birth is defined by the fragile under-developed lung needing to engage in air-breathing. Most preterm babies need respiratory support, but used inappropriately these life-saving therapies can increase the risk of long-term lung injury. This Fellowship will support a program designed to generate clinically meaningful outcomes through molecular, translational and clinical studies founded on strong physiological and biological principles and innovative research techniques.
Optimising Lung Protective Ventilation At Birth Using The Volumetric Response Of The Lung In A Preterm Lamb Model

Funding Amount
$611,021.00
Summary
Prematurity is a common problem which constitutes a major health-care burden. The preterm lung often cannot function independently at birth but is very fragile and susceptible to damage from the very first breathes of life. Life-saving mechanical ventilatory support must protect the lung from injury as well aid lung function. This project aims to improve ventilation strategies for supporting and protecting the preterm lung using novel approaches and innovative technologies.

Summary
This project aims to improve the resolution of bionic eyes and thus improve quality of living for the blind through novel electrical stimulation methods. Present commercial implants are inadequate in the amount of resolution they provide to conduct complex tasks such as independent navigation, reading and facial recognition. The proposed experiments using the new stimulation methods will inform a new generation of devices capable of high resolution without increasing the number of physical elect ....This project aims to improve the resolution of bionic eyes and thus improve quality of living for the blind through novel electrical stimulation methods.

Summary
Lack of oxygen supply before, during or immediately after birth can lead to severe disability or death. This occurs in about 1 in every 500 births and is one of the most important but unsolved problems in pediatrics. The costs (financial and other) to both the individuals involved, and the community in general, is very high. However the outlook for those affected by this condition is improving.

This occurs in about 1 in every 500 births and is one of the most important but unsolved problems in pediatrics. The costs (financial and other) to both the individuals involved, and the community in general, is very high. However the outlook for those affected by this condition is improving. Recent research has focused on the development of neural rescue therapies, which may decrease the extent of disabilities suffered by these children. The same treatments may also be helpful in children following near drowning and head trauma. Neural rescue therapies must be applied less than 24 hours following the event which has caused the reduction in oxygen supply. Thus, before these treatments can be tested, it is necessary to find a way to quickly tell which babies may benefit from the treatments. This study will trial a new method which is inexpensive and can be used without moving the baby away from its incubator. This technique involves a new application of an established technology to detect the redistribution of water within the brain one of the earliest signs of impending brain cell death. The research team consists of medical personnel from the intensive care nurseries of both the Royal Women's Hospital and the Mater Mother s Hospital, as well as scientific staff experienced in the use of this technology. If this technique is effective, it will enable babies to receive maximum benefit from new treatments and reduce long-term difficulties suffered by these children and their families.Read moreRead less
A Novel Approach To The Training Of Functional Standing Following Spinal Cord Injury

Funding Amount
$412,706.00
Summary
The study will employ a new type of functional electrical stimulation (FES), strength-endurance muscle conditioning and standing training to improve stance in SCI victims with incomplete paralysis. We will evaluate an innovative combination of muscle training and novel FES protocols which allow paralysed people to stand and perform upper limb functional tasks. The primary outcomes will be duration of standing, number of repetitions of standing and sitting and upper limb function while standing.

Summary
The ultimate goal of this project is to improve the ability of cochlear implant users to understand speech. The way in which a speech signal varies in amplitude over time provides useful information to the listener about the content of the speech signal. Currently, the way that the acoustic signal amplitude is converted to electrical signal amplitude for cochlear implantees does not take into consideration the very significant loudness summation present in multiple-electrode electrical stimulati ....The ultimate goal of this project is to improve the ability of cochlear implant users to understand speech. The way in which a speech signal varies in amplitude over time provides useful information to the listener about the content of the speech signal. Currently, the way that the acoustic signal amplitude is converted to electrical signal amplitude for cochlear implantees does not take into consideration the very significant loudness summation present in multiple-electrode electrical stimulation. That is, when there are multiple sequential current pulses on different electrodes over a short time, the resultant loudness is greater than the loudness due to individual current pulses. The lack of consideration of loudness summation effects has led to the amplitude variations in the acoustic signal not being accurately represented in the loudness variation perceived by the cochlear implantee. This project aims to develop a practical way of more accurately representing speech signal amplitude fluctuations for cochlear implantees by studying the effects of loudness summation. A second aim of the project is to study the effects on perception of using differently-shaped current pulses from those currently used. There is evidence from physiology experiments that using different shapes might cause the electrical stimulation to activate a more narrowly-spaced set of auditory neurons for each electrode. The application of results of both these studies will lead directly to improved perception of speech and other sounds by cochlear implantees, thus improving their communication ability and quality of life.Read moreRead less
