"We have developed a single-compartment, electrophysiological,
hypoglossal motoneuron (HM) model based primarily on experimental data
from neonatal rat HMs. The model is able to reproduce the fine
features of the HM action potential: the fast afterhyperpolarization,
the afterdepolarization, and the medium-duration
afterhyperpolarization (mAHP). The model also reproduces the
repetitive firing properties seen in neonatal HMs and replicates the
neuron’s response to pharmacological experiments. The model was used
to study the role of specific ionic currents in HM firing and how
variations in the densities of these currents may account for
age dependent changes in excitability seen in HMs. ..."
