“…(iv) Our HCO model consists of two neurons coupled by mutual inhibition. However, many biological CPGs contain more than two populations of neurons (Grillner 2003;Kiehn 2006;Kristan et al 2005;Varkonyi et al 2008;Smith et al 2007). A different analysis may be required to study the phase response properties of these CPGs.…”

“…As noted earlier, effective weight-bearing stepping can be generated in the absence of input from supraspinal centers. Often this is presumed to be possible because of the presence of central pattern generators in the spinal cord (Grillner, 2003). Since it is often assumed that without central pattern generation capability humans would be unable to generate locomotion without supraspinal input, i.e., following a brain or spinal cord injury, there has been considerable focus on the issue of whether such central pattern generators are present in the human spinal cord (Duysens and Van de Crommert, 1998).…”

“…Thus, alternating gaits like walk and trot are present at slower locomotor speeds, while synchronous gaits like gallop or bound evolve at fast locomotor speeds 1 and are mostly used during escape-like behaviours. The executive locomotor circuits that control the coordination of muscle activity is localized in the spinal cord 2–6 . Yet, the commands for initiation and gait selection may originate in different supraspinal structures.…”
