Pseudorabies Virus and the Functional Architecture of the Circadian Timing SystemDepartment of Neuroscience, University of Pittsburgh, Pittsburgh, PA 15260, USA Transneuronal tracing of neuronal circuitry with neurotropic viruses has provided valuable insights in the way in which the nervous system imposes temporal organization on physiological processes and behavior. The swine alpha herpes virus known as pseudorabies virus, or PRV, has been particularly useful in this regard. Early studies identified attenuated mutants with selective tropism for visual circuitry involved in circadian regulation, and subsequent experiments employing this virus have provided considerable insight into the polysynaptic organization of the suprachiasmatic nuclei and associated circuitry. This literature, which has emerged during the past decade, is the subject of this mini review.
