If LIP activity strictly reflected a broad timing system (like those described by centralized timing models), its activity would have a consistent relationship with time irrespective of
saccade direction.
In order to determine what factors are associated with firing rate changes, we generated a prediction of neural activity by convolving observed neural activity aligned with one
saccade direction with the intersaccade distribution times aligned with the other
saccade direction.

This movement - field plot shows that the number of spikes in the burst (color code) varies systematically with
saccade amplitude and
direction.
Individual trials are sorted according to
saccade amplitude and
direction, respectively.
Yet, all these features taken together fully explain how the SC population could encode the nonlinear kinematics, and at the same time generate straight
saccades in all
directions.
