Comparison of learned component of responses and initiation of pursuit for a PC with a large difference in eye velocity regression coefficients. Black and dashed traces show responses to step-ramp target motion and the learned component of pursuit. Arrows show the values of each curve during the appropriate measurement interval. Note that the data for the initiation of pursuit have a large transient response during the rapid eye acceleration, but a lower steady firing related to steady eye velocity. The latter is responsible for the value of the eye velocity regression coefficient for the responses to step-ramp target motion.
