Figure 8.

Comparison of the dynamic characteristics of different premotor cell types with those of extraocular motoneurons. A, B, The difference between the response phase of each cell type and the average motoneural phase (i.e., mean of AB and OM cells) during rotation (A) and translation (B) is illustrated for frequencies of 0.5, 2, and 4 Hz (cyan, PVP-I; purple, PVP-II; blue, c-EH; red, i-EH; green, PH-BT). Positive values indicate a phase lead relative to the average motoneural phase. Error bars illustrate SD.
