Abstract
The mammalian suprachiasmatic nucleus (SCN) consists of a cluster of small round peri-karya lying bilaterally adjacent to the third ventricle just dorsal to the optic chiasm (Christ 1969, Diepen 1962). The SCN appears to be one of the basic structures involved in generating biological rhythms; it receives a direct input from the retina (Hendrickson et al. 1972, Moore and Lenn 1972), and destruction of the SCN disrupts a variety of cir-cadian rhythms (Moore and Eichler 1972, Stephan and Zucker 1972, van den Pol and Powley 1979). In this chapter, the neuroanatomical organization and afferent and efferent connections of the SCN will be reviewed, giving particular attention to aspects possibly related to SCN control of circadian rhythms. Most of the information currently available is derived from studies conducted in rodents; however, where possible, comparative studies will be considered.
