Abstract(in Japanese) (See Japanese page)
Abstract(in English) Transcutaneous auricular vagus nerve stimulation (taVNS) is a non-invasive form of stimulation that has potential therapeutic benefits and is used to treat drug-resistant epilepsy and depression. Electroencephalogram (EEG) recordings can be used to detect the effects of taVNS on brain activity and behavior. However, taVNS can also interfere with EEG recordings as an artifact, affecting the analysis of EEG signals. This research proposes a method for removing the taVNS artifact from EEG recordings using an automatic detection algorithm that identifies the QRS complex (imitation of electrocardiogram and corresponding to stimulation onset, peak, and offset, respectively) of the taVNS artifact and remodels the stimulation for each EEG channel by identifying the QRS of the taVNS artifact and remodeling the stimulation to each EEG channel by subtracting the EEG signal with the resulting stimulation model. We found that the taVNS artifact can be easily detected by adding a stimulation reference electrode near the stimulation device. The artifact can be removed by creating a model based on the mean signal of the EEG channels. The resulting artifact removal shows no visible artifact in the time and frequency domain. Other artifacts, such as the cardiac artifact, are still visible in the resulting signal. We believe that the removed taVNS artifact and the presence of the cardiac artifact demonstrate the effectiveness and specificity of the proposed method.
