This model was contributed by A. Kozlov.
Simulation of locomotor neuronal networks of lamprey  using
biologically detailed neuron model . The simulation is based on the
segmental organisation of the spinal networks of lamprey  distributed
along the spinal cord to generate waves of left-right alternating activity
travelling from head to tail . Supraspinal neural populations are added
to study propagation of steering commands, from tectum to locomotor CPG.
