In this paper, I have introduced and solved a simple deterministic model of eye tracking that produces rich dynamical behavior. Some of its main features, notably the existence of a chaotic regime, are reminiscent of the anomalies reported in smooth pursuit eye tracking experiments with schizophrenia patients. By obtaining the state diagram of such a model as a function of target frequency and amplitude, we showed the existence of a chaotic regime characterized by a strange attractor in phase… Expand

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 dynamicsExpand
Inherited Real Risk of Schizophrenia: Pathogenesis, Bedside Diagnosis and Primary Prevention
The comprehension of the pathogenesis of schizophrenia finds a new impulse in studies on non- linear dynamics of EEG signals and in the growing genetic molecular evidence of the mitochondrial originExpand
A healthy dose of chaos: Using fractal frameworks for engineering higher-fidelity biomedical systems.
Overall, this work promotes the effectiveness of fractals in characterizing natural systems, and suggests moving towards using fractal frameworks as a basis for the research and development of better tools for the future of biomedical engineering. Expand
Improving predictability of the future by grasping probability less tightly
In the last 30 years, whilst there has been an explosion in our ability to make quantative predictions, less progress has been made in terms of building useful forecasts to aid decision support. InExpand
At the Edge of Chaos
The search for a unified conceptual framework for social work has floundered as the profession has struggled with general systems theory and, most recently, the eco-systems perspective. Social workExpand
From Complexity Science to Complex Thinking: Organization as Simple Location
Recent developments in the sciences of complexity have led to a rise in interest in the application of such insights to the understanding of social phenomena such as organization. This essay seeks toExpand

If L were negative (i.e.. stiffer restoring force for large errors), the peak-to-peak amplitude would then increase with increasing frequency
