Abstract
Elektroencefalografija (EEG) in funkcijska magnetna resonanca (fMR) sta neinvazivni metodi za merjenje možganske aktivnosti. EEG ima v nasprotju s fMR zelo visoko časovno ločljivost (več kHz), medtem ko ima fMR višjo prostorsko ločljivost. Sočasno snemanje EEG in fMR tako omogoča natančnejši vpogled v funkcije možganov. Največja slabost sočasnega snemanja EEG in fMR je močna interakcija med njima, saj se v EEG signalih inducirajo močni artefakti zaradi sprememb magnetnega pretoka. Predstavili smo robusten postopek in algoritme za odstranjevanje tovrstnih artefaktov iz EEG signalov. Z analizo učinkovitosti algoritmov smo dokazali ustrezno odstranitev artefaktov za nadaljnje analize.

Title:Robust procedure for artifact removal from electroencephalographic (EEG) measurements acquired during simultaneous functional magnetic resonance imaging (fMRI)
Abstract:
Electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) are noninvasive methods for measuring brain activity. EEG provides a very high temporal resolution, whereas fMRI provides high spatial resolution. A deeper insight into brain functions can be achieved by scanning the brain activity with simultaneous EEG-fMRI. The main downside of simultaneous EEG-fMRI scanning is a high EEG signal contamination caused by electromagnetic induction due to changes in magnetic flux. We presented a robust procedure and algorithms for artifact removal from EEG signal. We analyzed the performance of the procedure and showed a satisfactory artifact reduction for further analyses.

Keywords:EEG, fMRI, neuroscience, digital signal processing, digital filtering, general linear model
