Correlation dimension of optokinetic nystagmus as evidence of chaos in the oculomotor system.
The correlation dimension of optokinetic nystagmus (OKN) eye movements from a normal human subject was computed. Results indicate a value of about 2.8, indicating the possibility of chaotic dynamics in OKN. This was found to differ from the dimension of an artificial OKN signal with the same second-order statistics.
