Splet01. jan. 2009 · The EEG contains the technical artifacts (noise from the electricity, amplitude artifact, etc.) and biological artifacts (eye artifacts, EKG and EMG artifacts). This paper is aimed to eye-blinking artifact detection from the video which is recorded with EEG data simultaneously. SpletThe EEG findings in 40 shunted hydrocephalic patients tested after the onset of epileptic seizures are assessed. The salient point to emerge from the study is the higher frequency of anomalies, both specific (spikes, slow spikes, spike and wave complexes) and nonspecific (monomorphic and polymorphic slow waves) on the shunted hemisphere (19 cases) than …
Filtering and removal of artifacts in Biosignals
Splet14. jun. 2024 · The presence of artifacts in the EEG signals can cause a misunderstanding of the sought neurophysiological phenomena. In particular, the eye blink artifacts frequently contaminate the EEG and deteriorate its quality. Unfortunately, removing this artifact can lose useful information. The most popular approach in this field uses the independent … Splet08. maj 2024 · EEG recordings are generally affected by interference from physiological and non-physiological sources which may obscure underlying brain activity and hinder effective EEG analysis. In particular, cardiac interference can be caused by the electrical activity of the heart and/or cardiovascular activity related to blood flow. Successful EEG application … clan cranstoun
