Abstract
Lumbosacral segments of the cat spinal cord contain neuronal networks, or central pattern generators (CPGs), capable of providing the rhythmical output and basic synergistic patterns required for hindlimb locomotion (Grillner & Zangger, 1979). In the decade since Grillner (1973) first summarized work on locomotion in the spinal cat, the capacity of lumbosacral networks to regulate intralimb and interlimb coordination of the cat’s hindlimbs without benefit of supraspinal influences (Forssberg et al., 1980a-b; Rossignol et al., 1982; Smith et al., 1982) and/or movement-related feedback (Grillner & Zangger, 1979 & 1985; Perret & Cabelquen, 1980) has been studied extensively. Because much of this work has been reviewed recently (Grillner, 1981; Grillner & Wallen, 1985), the focus here will be on current information and issues that remain unsettled with regard to hindlimb locomotion in spinal cats (adult animals lesioned at T-12, tested 5–6 mo later) as opposed to spinal kittens (lesioned at 7–14 days of age, tested 3–6 mo later).
