PMID-6253605[0] Functional classes of primate corticomotoneuronal cells and their relation to active force
- monkeys made ramp and hold torque wrist movements/contractions.
- corticomotoneuronal cells identified by clear postspike facilitation of rectified EMG activity.
- all CM cells or PTNs were related to force - with a mixture/diversity of phasic, tonic, and ramp discharge rate profiles.
- torque trajectory rather than velocity signal seems to be the primnary determinant of cell firing rate...
- cells appear to be recruited at low force levels..with increasing rates as the torque increases.
- high firing rates observed > 100!
- and really low firing rate when there was no torque.
