Abstract

An experiment was conducted to map the 3D electroencephalogram (EEG) rhythms using the Zero-Crossings analysis (ZCA) method. The EEGs of five healthy volunteers were recorded during relaxed eye-closed state with flash light stimulation. These EEG signals were filtered for the alpha band using a fast Fourier transform based digital filter. From threshold Zero-Crossing points, periodic intervals of the alpha waves were determined and converted to instantaneous frequencies. The spatial dynamics of the alpha rhythm during flash stimulation using over-minute recordings were observed. It was found that 3D-EEG rhythm mapping is useful in the investigation of cortical structures and the interaction of the underlying rhythmic activity.
