OxTalks will soon be transitioning to Oxford Events (full details are available on the Staff Gateway). A two-week publishing freeze is expected in early Hilary to allow all events to be migrated to the new platform. During this period, you will not be able to submit or edit events on OxTalks. The exact freeze dates will be confirmed as soon as possible.
If you have any questions, please contact halo@digital.ox.ac.uk
Swallowing dysfunction (dysphagia) is a common problem after neurological diseases, with potentially life-threatening consequences including dehydration, malnutrition, aspiration and pneumonia, posing a substantial burden on healthcare resources. Exploring how the brain and swallowing muscles interact therefore becomes key to understanding the factors that can lead to dysphagia in disease states such as stroke. In my talk, I will first cover how the pharynx/swallowing is controlled by central pathways using brain imaging and brain stimulation based approaches. I will then examine how these neurophysiological pathways can be disrupted following neurological disease, and finally I will touch on how these pathways can be manipulated by neurostimulation to rehabilitate swallowing after neurogenic dysphagia associated with stroke and other neurological disorders.
