Network activity in the spinal cord induced by bath perfusion of NMDA. A, Sustained swimming rhythm recorded from motor nerves (m.n.) on opposite sides of a ∼700 μm length of spinal cord. B, Phase plot showing activity alternates between the two sides (also see shaded cycle in A). C, Rhythm continues despite phase uncoupling produced by 1 μm strychnine and 20 μm SR95531. D, Phase plot for record in C.
