Summary of the results of the three muscimol experiments in monkeys AL and CR. Column Q identifies the saccade vector quadrant (e.g., I: 0 ≤ φ ≤ 90 deg, etc.). Preinjection and postinjection data are quantified by the relation between the initial torsional eye position,

*r*_{A}^{x}, and the subsequent torsional displacement of the saccade,*d*_{AB}^{x}. The slope of this relation,*s*(dimensionless), is given in the left column, the correlation coefficient,*r*, in the center column, and the number of data points,*N*, in the right column. Offsets were indistinguishable from zero in all cases. Standard deviations were obtained by bootstrapping the data 100 times.*P*indicates whether the pre- and postinjection data are significantly different from each other.F2_152 , Significantly lower slope (

*P*< 0.0001);F2_150 , significantly higher slope. We have also analyzed the data by including a “dead zone” of 0.6 deg, which excluded torsional onset positions within a range roughly equal to the standard deviation of a normal Listing’s plane. In that case, correlation coefficients increased dramatically, and the lesion effects were even more prominent. For example, for the data presented in Figure 8 (quadrants I and III of experiment CR19), we found:

Prelesion: QI:

*s*= −0.54 (*r*= −0.63,*N*= 163); QIII:*s*= −0.39 (*r*= −0.53,*N*= 171);Postlesion: QI:

*s*= −0.09 (*r*= −0.17,*N*= 138); QIII:*s*= −0.35 (*r*= −0.62,*N*= 138).
