Medullary and C3–C4 propriospinal pathways underlying mammalian forelimb movement control

Proceedings of the National Academy of Sciences, Volume 123, Number 5, February 2026.
SignificanceOur study identifies a conserved medullary network, including the Lat-RM and CauM, that underlies the control of forelimb movements between species, while also revealing cortical differences potentially driven by task demands or between species…
