k_V and k_C, rate-position linear regression slopes for vergence and conjugate eye movement, respectively; T, threshold, with on-direction positive; FR-F, firing rate in far viewing; FR-AC, firing rate in near viewing with asymmetric convergence.

^*Slope significantly different from 0 (P < 0.001);

^†k_V/k_C significantly different from 1 (P < 0.001).
