Nonlinear dynamics in a complex cubic one-dimensional model for sensory psychophysics

A cubic recursion with complex variable, has different properties in the phase spases of the reals and the imaginaries. The separation of the dynamics of the parts may be interpretable in terms of sensory intensity signal transmission through higher neural networks in man.This work was supported by the Australian Research Grants Scheme, Grant No. A28515714I in 1986, held by Prof. Gregson, to whom requests for offprints should be directed.
