|title=Age- and speed-dependent modulation of gaits in [[DSCAM]]  mutant mice.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/29093169
|abstract=Gaits depend on the interplay between distributed spinal neural networks, termed central pattern generators, generating rhythmic and coordinated movements, primary afferents, and descending supraspinal inputs. Recent studies demonstrated that the mouse displays a rich repertoire of gaits. Changes in gaits occur in mutant mice lacking particular neurons or molecular signaling pathways implicated in the normal establishment of these neural networks. Given the role of the Down syndrome cell adherence molecule ([[DSCAM]]) to the formation and maintenance of spinal interneuronal circuits and sensorimotor integration, we have investigated its functional contribution to gaits over a wide range of locomotor speeds using freely walking mice. We show in this study that the [[DSCAM]]  mutation, while not precluding any gait, impairs the age- and speed-dependent modulation of gaits. It impairs the ability of mice to maintain their locomotion at high treadmill speeds. [[DSCAM]]  mutation induces the dominance of lateral walk over trot and the emergence of aberrant gaits for mice, such as pace and diagonal walk. Gaits were also more labile in [[DSCAM]]  mutant mice, i.e., less stable, less attractive, and less predictable than in their wild-type littermates. Our results suggest that the [[DSCAM]] mutation affects the behavioral repertoire of gaits in an age- and speed-dependent manner. NEW
