Raster Plots of Motoneurons
 
 
Injecting the same current intensity in the soma of all MNs of a nucleus, one can see that the smaller MNs discharge at a greater firing rate than the larger ones. The figure below shows the spikes of all motoneurons of a neural nucleus, after a step of 30.0 nA was applied to the soma of all motoneurons. The ordinate is the index of each motoneuron.
