Celestial orientation and setting of the biological clock in the southern cricket frog Acris gryllus can be cued by light stimuli received by extraoptic receptors in the brain. These extraoptic photoreceptors may also be used in learning new orientational directions. A mechanism for a light-activated biological clock is discussed.
