Cellular bases of a vertebrate locomotor system-steering, intersegmental and segmental co-ordination and sensory control

Brain Res Brain Res Rev. 2002 Oct;40(1-3):92-106. doi: 10.1016/s0165-0173(02)00193-5.

Abstract

The isolated brainstem-spinal cord of the lamprey is used as an experimental model in the analysis of the cellular bases of vertebrate locomotor behaviour. In this article we review the neural mechanisms involved in the control of steering, intersegmental co-ordination, as well as the segmental burst generation and the sensory contribution to motor pattern generation. Within these four components of the control system for locomotion, we now have good knowledge of not only the neurones that take part and their synaptic interactions, but also the membrane properties of these neurones, including ion channel subtypes, and their contribution to motor pattern generation.
