Table 3. Modulation onset of activity of DN cells for the two animals: Earliest onset of individual DN cells.
Monkey | Cell group | Mean | SD | n | Range |
M | DNC all | −93.1 | 29.4 | 65 | −150 to −10 |
DNC inc | −95.9 | 26.6 | 51 | −150 to −30 | |
DNC dec | −82.9 | 37.3 | 14 | −130 to −10 | |
S | DNC all | −92.1 | 38.2 | 19 | −150 to −10 |
DNC inc | −85.0 | 37.6 | 16 | −150 to −10 | |
DNC dec | −130 | — | 3 | −130 |
The same conventions as in Table 1. DNC all: all DN cells. DNC inc: DN cells showing increased activity as the earliest modulation regardless of movement direction. DNC dec: DN cells showing decreased activity as the earliest modulation. There was significant difference between DNC inc and DNC dec in monkey S (p<0.002, Mann-Whitney U-test), but not in monkey M (p<0.27, Mann-Whitney U-test).
