Summary
Now that newborn hearing checks are available, hearing loss can be picked up soon after birth and hearing aids are fitted shortly after. Although procedures exist for checking that the devices make sounds audible, there is no way to evaluate their effectiveness for supporting a child’s auditory discrimination. This study aims to 1) develop new clinical tools for assessing infants’ auditory discrimination, and 2) determine whether early discrimination predicts spoken language at 3 years of age.
Early Indicators Of Noise Injury: Are Decreased Auditory Processing Skills Evident In Noise-exposed Adults Prior To Diagnosis Of Hearing Loss?

Funding Amount
$367,605.00
Summary
Recent research indicates that noise-exposed individuals with similar hearing thresholds to non-noise exposed counterparts are more likely to have diminished temporal and spectral auditory processing abilities. This research aims to determine the relationship between noise exposure levels and auditory processing difficulties; the influence of musical training in ameliorating these difficulties; and a neurological model of causation, operation and possible remediation of these difficulties.
NEU-HORIZONS: The Neuroprotection And Therapeutic Use Of Riluzole For The Prevention Of Oxaliplatin Neurotoxicity Study.

Summary
Colorectal cancer is the second most commonly diagnosed cancer in Australia, with more than 13500 cases recorded annually. Oxaliplatin is an effective chemotherapy for the treatment of colorectal cancer. The major side-effect of oxaliplatin is the development of nerve damage that leads to loss of feeling in the hands and feet and significant disability. The aim of this study is to conduct a trial of a new treatment for oxaliplatin-induced nerve damage.
Organization Of Descending Auditory Projections From Inferior Colliculus To Cochlear Nucleus

Summary
Sensory information gains awareness by ascending brain pathways to reach consciousness. Descending projections, however, have grown in importance because of implications for feedback management of ascending signals. Studies of these pathways will provide insight into auditory processing with respect to selective volume control, calibration adjustments between the two ears, and the extraction of signals from background noise. The data could lead to new strategies for treating hearing disorders.
Studies Of The Effects Of Asymmetric Hearing Loss On The Brain

Summary
Hearing loss impairs the normal development and maintenance of auditory pathways. Irreversible pathologies persist when hearing is not restored in a timely manner. While cochlear implantation is the accepted treatment for profound sensorineural hearing loss, there is significant variability in outcomes. Some of this variability is linked to the degree of hearing asymmetry. Thus, we propose to study brain changes in the auditory system that accompany asymmetric hearing impairment.
Nodal Function In Peripheral Neuroinflammatory Disorders: Target Antigens, Functional Significance And Treatment Response

Funding Amount
$605,172.00
Summary
Inflammatory neuropathies are autoimmune disorders which produce severe disability and represent a costly burden to the healthcare system, but the causes remain unknown. Recent evidence from our team suggests that antibodies against parts of the peripheral nerve at the node of Ranvier are involved. The project aims to identify these specific targets and monitor treatment responsiveness, stabilise nerve function and prevent persistent disability.
Long-term Nerve Damage In Cancer Survivors: Identification Of Risk Factors And Optimal Assessment Strategies

Funding Amount
$850,172.00
Summary
Nerve damage following chemotherapy treatment leads to early treatment cessation and long-lasting disability, developing with commonly used chemotherapies. There is a critical need to understand the mechanisms, optimize clinical assessment and develop interventions to prevent nerve damage. This project is designed to detect the impact of long-term nerve damage in cancer survivors and develop a risk profile based on clinical, neurophysiological and genetic factors.
SENSORIMOTOR AND AUTONOMIC DYSREGULATION IN HEREDITARY SENSORY AND AUTONOMIC NEUROPATHIES

Funding Amount
$50,406.00
Summary
Specific genetic mutations can lead to widespread changes in the body. Here we are looking at the congenital Hereditary and Sensory Autonomic Neuropathies, the most common of which primarily affects Eastern European Jews. Affected individuals have difficulty walking and controlling their blood pressure, and also have an indifference to pain. This series of experiments aims to increase our understanding of the underlying neurophysiological disturbances.
Development Of The Listening In Spatialized Noise - Tonal Test (or LiSN-T)

Funding Amount
$227,136.00
Summary
In this project a novel listening test software will be developed for diagnosing spatial processing disorder in children. These children often have difficulties in understanding teachers in classrooms, which can significantly impact their ability to learn. The developed software will be specifically designed for diagnosing 5-year old children, before they enter primary school, and in contrast to existing tests will be independent of their language background.
