Parameters of fast CT5, CT6mod, and CT6slow neurons
| Conduction time (ms) | Conduction velocity (m/s) | % step related | Frequency at rest (imp/s) | Frequency simple (imp/s) | Frequency complex (imp/s) | % with receptive fields | |
|---|---|---|---|---|---|---|---|
| CT5 | 0.9 | 40.1 | 94% | 14.4 | 15.2 | 18.4 | 100% |
| CT6mod | 8.7 | 5.2 | 39% | 0.4 | 1.0 | 1.4 | 29% |
| CT6slow | 32.0 | 1.0 | 3% | 0.2 | 0.03 | 0.08 | 9% |
The first three columns show, for the three types of CT neurons studied, the mean antidromic conduction times, the mean conduction velocities, and the percentage of neurons that showed step-related responses during simple and/or complex locomotion. The next three columns show, for all members of these populations, the mean firing frequencies while subjects were at rest and engaging in simple or complex locomotion. The last column shows the percentage of each population that had a sensory receptive field.
