Abstract: We
have used a set of properties of the interactions among neurons in order to
develop a computer model for a spinal reflex circuit controlled by a central
pattern generator. This model is based on the idea that the responses of spinal
alpha-motoneuron to the sensorial stimulation can be modulated by the
synchronous oscillatory activity within the sensorimotor system. We have modeled
the central pattern generator as being a set of 1000 coupled oscillators
distributed on square
lattice and each lattice element containing 10 closer neighbor oscillators. The
model equations take into account, the synaptic characteristics of
somatodendritic membrane of neurons in a morphofunctional unity of spinal reflex
activity. By means of numerical simulations of the Kuramoto model, we simulated
the dynamical behavior of a central pattern generator. Our results are in
agreement to some experimental data from literature.
