Summary

Cephalopods (octopus, squid, cuttlefish) are among the most intelligent invertebrates, with highly developed nervous systems which provide excellent model systems for investigating basic questions in neuroscience. Within the last five years, many of the powerful techniques of molecular biology and electrophysiology have been applied to cephalopods, with exciting results. In 32 chapters, this book provides a comprehensive overview of the functioning of the cephalopod nervous system, from the cellular level to their complex sensory systems, locomotion, learning, and social behavior. It will be of interest to both vertebrate and invertebrate neurobiologists, and by anyone interested in the basic principles that control neural function.
