Outline of Final Research Achievements |
Dysphagia often causes aspiration pneumonitis that is a main cause of death in elderly people, but the neural process of swallowing has been hardly revealed. In the present study, we aimed to clarify the neural process of swallowing in order to develop BMIs for swallowing support. Firstly, we developed a system that simultaneously measures intracranial EEGs and swallowing movements quantitatively. Then, we used this system in 4 patients with epilepsy who underwent the placement of subdural electrodes. In all patients, high gamma band activity was observed in the lateral sensorimotor area during swallowing and disappeared rapidly after the swallowing. It is feasible to develop BMIs supporting swallowing by detecting this high gamma band activity.
