Neural regulation of circadian rhythms

The growing interest of both neuroscientists and chronobiologists in the neural mechanisms underlying circadian phenomena is reflected in the appearance of several recent reviews. The present review includes essentially all animal species for which significant information exists, but this survey is necessarily limited by the scope of our interests and competence. Although we have included data on both invertebrate and vertebrate species, our emphasis throughout is on mammals. Only a brief historical review is provided as background to the current literature.
