Summary
Cough is the most prevalent symptom of lung disease and the most common reason for people to seek medical advice. However, cough neural processes are poorly defined and as a result current cough therapies are largely ineffective making cough a significant unmet clinical problem. This project will novel viral strategies to dissect and manipulate cough neural pathways in the brain, providing insights into the neural processing of airway sensations and coughing.
Developing A Prototype Of A Next Generation Brain Computer Interface

Summary
Persons affected by quadriplegia and hemiplegia from stroke and spinal cord injury have few treatment options. Brain Machine Interfaces reconnect brain to a prosthetic limb, bypassing damaged nervous system. Our group has developed a BMI that can be implanted minimally-invasively, inside a blood vessel in the brain. We propose to manufacture a world-first device for a human clinical trial pilot study. The aim is to restore mechanical control over the physical environment for a paralysed patient.
Many infants and children suffer from bowel motility disorders, for example, chronic constipation affects up to 1 in 10 children. However, the cause of many of these paediatric motility disorders remains unknown. In this project, we will examine the development of wiring of the nervous system that controls bowel motility. This is the first study to investigate the development of cell-cell communication during early stages of nervous system development.

Summary
Epilepsy is the most common serious chronic neurological disease in the community, affecting up to 3% of the population in a lifetime and 0.5-1% at any one time. Absence epilepsy is one of the most common types of epilepsy, most frequently seen in childhood and teenage years that may persist into adulthood. Anti-epileptic drugs are effective in controlling absence seizures in most patients, however there is an important group (20-40%) of patients in whom the absence seizures remain uncontrolled ....Epilepsy is the most common serious chronic neurological disease in the community, affecting up to 3% of the population in a lifetime and 0.5-1% at any one time. Absence epilepsy is one of the most common types of epilepsy, most frequently seen in childhood and teenage years that may persist into adulthood. Anti-epileptic drugs are effective in controlling absence seizures in most patients, however there is an important group (20-40%) of patients in whom the absence seizures remain uncontrolled with current medications. Recently there has been considerable interest in the role that chemical in the brain, such as neuropeptide Y (NPY), may play in epilepsy. The research proposed will examine the role of NPY in several animal models of absence epilepsy. We have recently shown that NPY suppresses absence seizures in a rat genetic model of generalised epilepsy, and that this appears to be mediated by Y2 receptors. This work will build on these novel findings, and determine the localisation of the effect within the brain, and the underlying mechanism. We will check NPY effects across several models in different species, a genetic rat model with spontaneous seizures, and in mice treated with a chemical to induce seizures. This will determine its broad applicability. We will also determine the effects of removal of NPY or NPY receptors on the effects of NPY on seizure expression. Finally, brain recording techniques will be applied to determine the mechanism and site within the brain underlying the protective actions of NPY. The project has the potential to provide novel insights into the role of NPY in the expression and modulation of absence seizures. NPY related mechanisms might represent targets for the development of a new class of therapeutic agents for the treatment of absence epilepsy. Targets that are identified as being important in the expression of absence seizures may also prove to be relevant in other types of generalised epilepsy syndromes.Read moreRead less
