Abstract :
A method for the visualization of the electroencephalogram (EEG) in phase space is described. The signal is transformed from the time domain to phase space by measuring the correlation dimension of the data and constructing the attractor in the required embedding space, which is normally of dimension 3 to 8. A singular value decomposition is used to obtain a good projection to 3-D. Animation of a series of 2-D rotated projections provides a way to visualize the fine structure of the reconstructed 3-D attractor. Examples and a computer package are briefly described
