Figure 4:

Model reproduces known experimental properties of alpha motor neuron activity. In all panels, experimental data from literature are to the left and simulations using our model are to the right. Note that these are qualitative reproductions. (a) Self-sustained oscillations (Heckman, Johnson, Mottram, & Schuster, 2008). (b) Triphasic pattern of muscle contraction during rapid limb movement (Ghez, 1991). (c) The match between spiking patterns for periodic movements in (left) Joachim Büdingen and Freund (1976) and (right) our simulation results, all for low movement speeds (ω < ω_c). The gray bar at the bottom of each plot represents 0.5 s.
