As flexor and extensor muscle activities alternate during rhythmic movements such as walking, it is often assumed that the responsible neural circuitry is similarly exhibiting alternating activity1. <strong><span style=\"color: #ff0000;\">Here we present ensemble recordings of neurons in the lumbar spinal cord that indicate that, rather than alternating, the population is performing a low-dimensional \u2018rotation\u2019 in neural space, in which the neural activity is cycling through all phases continuously during the rhythmic behaviour<\/span><\/strong>. The radius of rotation correlates with the intended muscle force, and a perturbation of the low-dimensional trajectory can modify the motor behaviour. As existing models of spinal motor control do not offer an adequate explanation of rotation1,2, <strong><span style=\"color: #ff0000;\">we propose a theory of neural generation of movements from which this and other unresolved issues, such as speed regulation, force control and multifunctionalism, are readily explained<\/span><\/strong>.\u201d<\/p>\n<p style=\"text-align: justify;\">Henrik Lind\u00e9n, Peter C.
