🧠 New paper by Wimalasena, Pandarinath, AuYong et al: #spinal #interneuron populations form a low-dimensional #manifold that robustly organizes step cycles.
Distinct regions of the manifold mark flexion–extension transitions, and a specific “hold region” tightly controls cycle duration. Deletions emerge as failures to enter the flexor region, giving a dynamical signature of disrupted CPG function.

"The Loco-Motion" (or "#Locomotion") is a #popSong written by American songwriters #GerryGoffin and #CaroleKing. "The Loco-Motion" was originally written for the R&B singer #DeeDeeSharp, but Sharp turned the song down. The song is especially notable for making three appearances in the American top 3, each in a different decade: in 1962 by #LittleEva (U.S. No. 1); in 1974 by #GrandFunkRailroad (also U.S. No. 1); and in 1988 by #KylieMinogue (U.S. No. 3).

🧠 New #preprint by Komi et al. (2025): Neural #manifolds that orchestrate walking and stopping. Using #Neuropixels recordings from the lumbar spinal cord of freely walking rats, they show that #locomotion arises from rotational #PopulationDynamics within a low-dimensional limit-cycle #manifold. When walking stops, the dynamics collapse into a postural manifold of stable fixed points, each encoding a distinct pose.
