Population characteristics of hindlimb-related neurons during unconstrained and narrow-path walking. A: PTNs with fast axonal conduction velocities. B: PTNs with slow axonal conduction velocities. C: neurons responsive to passive movements in the hip joint. D: neurons responsive to passive movement of the knee joint. E: neurons responsive to passive movement in the ankle joint or palpation of muscles and skin on the paw. Other designations are as in Fig. 9.
