AB  - Motoneuronal spike trains were generated according to a simple model assuming 
      algebraical summation of the afterhyperpolarization (AHP) curve and noisy 
      synaptic inflow. An influence of various model parameters on the relationship 
      between standard deviation (SD), sigma, of interspike intervals (ISIs) and their 
      mean value, Tm, was studied. A typical sigma(Tm) relationship resembled those 
      obtained experimentally and consisted of two parts: a short-interval part with 
      constant sigma and a long-interval part where sigma increased linearly with 
      increasing ISI. It is concluded that the placement of the range of transition 
      between short- and long-interval parts of the plot depends on the properties of 
      the motoneuron and not on those of the synaptic inflow. The break-point interval 
      of the plot is correlated with the AHP duration but is shorter than it. Further, 
      not only are the curves for shorter AHP durations shifted towards shorter ISIs, 
      but they also have lower SDs at their short-interval parts.
