Abstract

The human pupillomotor response to light (the pupil light reflex -- PLR) is an example of nonlinear biological systems. The time characteristic of the PLR response is determined by the successive activation of the parasympathetic and sympathetic innervation of the iris muscles. The shape of characteristics is typically evaluated from the changes in pupil size following a pulse stimulation. The paper presents the system for studies of the dynamic behavior of the pupillary system. Results of the experiments and analysis are presented.
