| "2D slice of 3D representation of 4-second epoch of EEG from the olfactory system of the brain of a rat, awake but resting motionless. The trajectory of a point moving through this space in time traces the subspace that is occupied by a strange attractor. We have colored it red when the fourth variable is negative and blue-white when it is positive. The Hausdorff dimension is 5.92 and we are unable to find geometric order." |
