"Windup is characterized as a frequency-dependent
increase in the number of evoked action potentials in dorsal
horn neurons in response to electrical stimulation of afferent C-fibers.
...
The approach presented here relies on mathematical and
computational analysis to study the mechanism(s) underlying windup.
From experimentally obtained windup profiles, we extract the time
scale of the facilitation mechanisms that may support the characteristics
of windup.
Guided by these values and using simulations of a
biologically realistic compartmental model of a wide dynamic range
(WDR) neuron, we are able to assess the contribution of each
mechanism for the generation of action potentials windup.
