MRNs with kV > kC. The right MRN is cell 31 in Table 2. A: 10° leftward saccade showing the classic agonist pulse-slide-step pattern in both firing rate and right MR muscle force. B: 20° asymmetric convergence in which the MFT-instrumented right eye maintained its position and showed a large increase in firing rate but no increase in muscle force. C: 20° symmetric convergence. D: the firing rate-eye position sensitivity for vergence (▵; kV = 7.8 spikes/s per deg) was higher than that for conjugate movements (○; kC = 5.4 spikes/s per deg).
