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

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.

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.
Anandamide activated chloride channels in sensory neurons. We are seeking to understand how the nerve cells that sense our environment are regulated by signalling molecules produced by our body. Understanding how these cells function in normal conditions is essential as basis for understanding how they may function abnormally in physically stressful situations or in chronic pain conditions. The work may eventually lead to better treatments for a wide range of disorders that involve the sensory ....Anandamide activated chloride channels in sensory neurons.

The role of intracellular calcium in fibre-type specific gene expression in skeletal muscle. Muscles contain different fibre types whose composition can be changed by activity. The aim of this proposal is to identify the intracellular mechanisms which control fibre type. Our hypothesis is that different patterns of intracellular calcium determine the pattern of gene expression which determines fibre type. Understanding how gene expression is regulated is a central issue in biology.
Peripheral and central mechanisms of sensory coding and integration. The research described in this proposal seeks to provide generic answers to fundamental questions about sensory processes, the nature of perceptual experience, and how these are subserved by the nervous system. The study of inter-sensory interactions in perception has the potential to be incorporated into the development of virtual reality-type computer-based technologies. The neurophysiology research will provide basic informa ....Peripheral and central mechanisms of sensory coding and integration.

The study of inter-sensory interactions in perception has the potential to be incorporated into the development of virtual reality-type computer-based technologies. The neurophysiology research will provide basic information that has the potential to deepen our understanding, and even enhance possible treatment, of neurological conditions that involve sensory systems.Read moreRead less

The role of spike patterning in shaping human perception of tactile stimuli. Every touch sensation from our fingertips is conveyed to the brain through the nerves by means of electrical impulses similar to any digital device. Using unique technology developed in our lab we can intercept this neural communication and insert our own messages to test how these signals are interpreted and converted into perceptual experiences. We aim to reveal the rules by which timing of neural signal patterns shap ....The role of spike patterning in shaping human perception of tactile stimuli. Every touch sensation from our fingertips is conveyed to the brain through the nerves by means of electrical impulses similar to any digital device. Using unique technology developed in our lab we can intercept this neural communication and insert our own messages to test how these signals are interpreted and converted into perceptual experiences. We aim to reveal the rules by which timing of neural signal patterns shapes the perception of touch - specifically intensity and frequency of vibration. By recording signals from neurons and by testing human perception, we will learn about neural processing mechanisms. The new knowledge generated about sensory coding will be essential for rendering a virtual sense of touch.Read moreRead less
The encoding of friction by tactile mechanoreceptors - the key to fingertip force control during dexterous object manipulation by humans. Unmatched human ability to control the hand so that brittle objects are gently held without slipping, or being crushed by excessive force rely on sophisticated tactile sense in the fingertips. This project will record and analyse signals which human nerves are sending from fingertip receptors to the brain centres controlling hand actions.
