Strange attractors that govern mammalian brain dynamics shown by trajectories of electroencephalographic (EEG) potential

Four examples are shown which demonstrate the use of computer graphics to visualize chaotic attractors from EEGs (electroencephalograms). The recordings are made from multiple sites: factor analysis is used to partition the variance into orthogonal components, and the largest three serve best to represent the dynamics in the three Euclidean dimensions accessible using a flight simulator. It is then possible to observe the trajectories of attractors in 3-space, using color or time slices to suggest yet higher dimensions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
