Regularly firing neurones in the rat suprachiasmatic nucleus

  • G. A. Groos
  • J. Hendriks


The spontaneous discharge of some suprachiasmatic neurones in vivo and in vitro was found to exhibit a very constant interspike interval. In vivo these cells were comparatively rare and appeared to be mutually coupled. These findings are discussed in relation to coupled oscillator theories of circadian rhythm generation.
