Probability of synchronization increased with saccade velocity, and synchronization was more likely for saccades to targets. (A) For each animal and each type of saccade, we separated the movements based on their peak velocity and amplitude into high and low vigor. Error bars are SD. (B) High-vigor saccades exhibited a greater probability of SS synchrony than low-vigor saccades. Error bars are SEM. (C) A comparison of high-vigor saccades to targets vs. high-vigor other saccades. Amplitudes and velocities were larger for other saccades, yet saccades to targets were more likely to exhibit synchronization of SSs. Error bars are SEM.
