Dynamic analysis of disparity vergence eye movements: beyond the main sequence

Abstract

Classically, the primary tool for studying dynamics in vergence and other eye movements has been the main sequence. The main sequence is a plot of peak velocity versus response amplitude and is particularly useful for comparing a large number of eye movements over a range of amplitude magnitudes. However, the main sequence does not represent the dynamic details of a movement. A new methodology is explained which quantifies dynamics of eye movements over a larger region of the transient response. These new indices were used to differentiate between subtle, but important differences in movement dynamics.
