Modelling 3D saccade generation by feedforward optimal control
Fig 11
Component stretching in oblique saccades (after JAED minimization).
In these examples, the horizontal component was kept fixed at 8.0 deg, while the vertical component varied from 0 to 30 deg in 5 deg steps. (A) Horizontal and (inverted) vertical velocity profiles of the oblique saccades. Note that the velocity profiles approximately match in duration. This is especially clear for the larger (≥15 deg) vertical components (green, red, cyan and yellow traces). (B) Peak velocity of the horizontal component depends on the saccade direction. Dashed line: cosine prediction for a common-source vectorial drive ([47] see also Table 3).
