Summary
Australia has one of the highest rates of diabetes in the world. Diabetes may be complicated by the development of nerve damage, causing weakness and pain in the upper and lower limbs. The cause remains unclear and there are no tools available for its early detection. This study will provide further information about the cause of diabetic neuropathy and will investigate more sophisticated means for its early detection.
Persistent Firing In Cortical Interneurons: Mechanisms And Potential Anticonvulsant Role

Summary
The normal brain treads a fine line between too much electrical activity (epilepsy) and too little (sedation). We have discovered a class of brain cell that seems to behave like a sentinel, monitoring brain activity for signs of epilepsy. If a seizure occurs, this cell switches on an electrical brake that dampens excess activity. In this project we will study how this brake works and whether it really can inhibit seizures. Our research may lead to better treatments for epilepsy.
The Final Common Channel: Measurement Of Nerve Excitability In Epilepsy.

Summary
Epilepsy may be due to either one single genetic mutation or a combination of several gene-environment interactions, affecting how ion channels function. It is not possible to directly interrogate channels in the living human brain but, because similar channels are found in peripheral nerve, much may be learned about aberrant channel function from peripheral nerve. This project aims to measure peripheral nerve excitability in epilepsy patients, using it as a marker of the final common pathway of ....Epilepsy may be due to either one single genetic mutation or a combination of several gene-environment interactions, affecting how ion channels function.

The Biophysical Basis Of HCN Channels In Human Peripheral Nerve

Funding Amount
$50,315.00
Summary
Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels play an important role as pacemakers in the cardiac and nervous systems. HCN channel dysfunction is implicated in a number of disorders including neuropathic pain and epilepsy. My aim is to determine the kinetics and voltage dependence of HCN channels in human peripheral nerve in vivo. Understanding these channels is a prerequisite to the development of safe targeted therapies against neuropathic pain.
Mechanisms Of Autoantibody Mediated Axonal Injury In Inflammatory Demyelinating Neuropathies

Funding Amount
$580,197.00
Summary
Destruction of nerve fibres (axons) accompanies demyelination and may be responsible for most of the deficit in multiple sclerosis and immune neuropathies. This project will investigate the role of recently described antibodies against a normal component of the axon in axonal damage in both animal models and in patients with immune neuropathies. The project could have a major effect on approaches to management of these diseases.
AUSSPRINT:Australian Study Of The Effects Of Strict Potassium Restriction On Neuropathy In Chronic Kidney Disease.

Funding Amount
$252,653.00
Summary
Patients with chronic kidney disease, when compared to healthy controls, are weaker, less active and have reduced exercise capacity. These physical limitations have in turn been linked to low quality of life and higher mortality rates. Studies have shown that high blood levels of potassium may cause nerve damage in chronic kidney disease patients.This study explores the benefits of strict potassium restriction as a means of reducing neuropathy rates in patients with chronic kidney disease.
Neural Plasticity Following Lesions Of The Central Nervous System In Multiple Sclerosis

Funding Amount

Summary
The brain and nervous system can adapt to injury and disease. The compensatory changes underlying this plasticity can ameliorate disability. This project will investigate the underlying mechanisms in patients with multiple sclerosis, by examining changes in the properties of nerve fibres in the peripheral nerve. The rationale for the project is that the properties of peripheral nerve fibres can reflect, at least in part, the properties of their cell bodies within the spinal cord.
