Topic: locomotor speed

Kinematics and neuronal circuits for straight-trajectory forward locomotion have been well-explored. However, only few investigations delved into the various motor strategies for locomotor turning and the corresponding neuronal drivers. Recently, we revealed in mice that the unilateral activation of V2a reticulospinal neurons in the gigantocellular nucleus (V2aGRN) induces turns marked by a temporary pause in stepping and an ipsilateral bending of the body axis. We have also shown that these features are driven independently by spinally-projecting V2aGRN subsets accessed from L2 and C2 respect
