Abstract

This chapter deals with the neurons that constitute the majority of spinal neurons and are the main source of input to motoneurons, and therefore of critical importance for all motor reactions. The description of spinal interneurons focuses on the properties of their main populations and on the operation of basic interneuronal networks, both in animals and humans.
