Figure 2.

A, B, Eye position (Pos), eye velocity (Vel), and neural responses from an EH neuron during horizontal (Hor) pursuit (A) [15° up, center, and 20° down (dn)] and vertical (Ver) pursuit (B) [15° left (L) center, and 15° right (R)]. IFR, Instantaneous firing rate; Tor, torsion. Insets, Eye velocity in head coordinates (monkey drawing). Data are shown in gray, with superimposed black solid lines illustrating linear regression (shown for eccentric targets). C, D, Response gain versus eye position for horizontal and vertical pursuit. Solid lines, Linear regression.
