Electroencephalography (EEG) signal analysis and EEG-based preliminary examination has been proposed in the clinical brain death determination. In our previous studies, with knowing the clinical diagnosis of the patient, the result that obtained by using independent component analysis (ICA) for quasi-brain-death EEG is the same with that from the standard clinical procedure. In this paper, we present...
Sleep spindles are groups of rhythmic activity, with a waxing-waning morphology, and are considered a hallmark of stage 2 of the sleep electroencephalogram (EEG). They are present predominantly in stages 2, 3 and 4 of the sleep EEG. Spatial analysis of sleep spindle scalp EEG and EEG inverse problem solutions have provided evidence for the existence of two distinct sleep spindle types, ldquoslowrdquo...
We compare the efficiency of the independent component analysis (ICA) decomposition procedure against the difference wave (DW) procedure in the analysis of the mismatch negativity (MMN). The comparison was made using two different experimental paradigms under a passive oddball protocol. The event related potential (ERP) recordings were decomposed into the MMN-like and non-MMN-like independent components...
