Striatonigral neurons comprise diverse subtypes, yet their specific roles in locomotion regulation are not fully understood. Here, authors demonstrate that the Calb1+ subtype promotes locomotion, while the Kremen1+ subtype terminates ongoing movement by inhibiting the activity of Aldh1a1+ dopaminergic neurons via GABBR1 receptors.
