Recording of EEG during functional MRI experiments: Artefacts
We examined seizure outcome Cfree ,from seizures however minor vs. continuing seizures however infrequent) 5 years post-TLES for mesial temporal sclerosis in 82 consecutive patients, aged 8-43 years, who underwent pharmacologically activated sphenoidal EEG pre-operatively (12 with extracranial ictal monitoring (VT), 70 without). Fifty-six had suffered an early-childhood complicated convulsion (...
متن کاملThe effect of EEG recording on functional MR image quality
Introduction The recording of electroencephalogram (EEG) inside the MR scanner has gained increasing interest, particularly in the field of functional MRl (fMRI) [ 1,2]. EEG recording during fMRI can impair the image quality due to magnetic susceptibility of the EEG electrode assemblies and electromagnetic noise from the EEGrecording equipment. We therefore investigated (1) local signal drop ou...
متن کاملSyncope during EEG recording.
A 75-year-old man had several syncopes with severe skull contusions (figure 1). These events were not preceded by vegetative symptoms such as nausea, dizziness, or palpitations. Holter-EKG was normal and an EEG was performed for suspected epilepsy, during which complete atrioventricular block without ventricular escape-rhythm occurred (figure 2A). Six seconds later, the EEG showed progressive s...
متن کاملCo-recording of EEG and fMRI data: EEG artifact removal
The electroencephalogram (EEG) is a standard technique to record and study the brain activity with a high temporal resolution (ms). BOLD fMRI (Blood Oxygenation Level Dependent functional Magnetic Resonance Imaging) is a non-invasive imaging method that allows the localization of activated brain regions with a high spatial resolution (mm). The co-recording of these two complementary modalities ...
متن کاملEEG-vigilance and BOLD effect during simultaneous EEG/fMRI measurement
Different EEG-vigilance stages from full alertness to sleep onset can be separated during rest. Also fMRI research recently focused on the resting condition and identified several resting state networks. In order to deepen the understanding of different levels of global brain function from relaxed wakefulness to sleep onset the association between EEG-vigilance stages and BOLD signals was analy...
