The existence of a true neuronal consensual pupillary reflex (CPR) in birds has long been debated. In this century Noll (Noll, A. (1915). Archiv für Physiologie (Leipzig), 350-372.) claimed to observe a neuronal CPR in a pigeon, but this was contradicted by Levine (Levine, J. (1955). Science, 122, 699.), who observed a direct transillumination effect (Durchleuchtungs-effekt) due to the retinas of the two eyes of the pigeon being in close apposition. To determine if a neuronal CPR exists, we transected the optic nerves of 28 chicks and observed and videotaped the direct and indirect pupillary responses. Twenty-one of the chicks exhibited no direct response in the operated eye but did exhibit an indirect pupillary response. The non-operated eye showed a direct but no indirect response. These results conclusively demonstrate for the first time that a true neuronal CPR does exist in chickens.
