Abstrakt: The neurotoxin 3-acetylpyridine was administered to 20-day-old rats to produce lesions of the inferior olive-climbing fiber projection to the cerebellum. Cerebellar cGMP levels were determined 6 h, 24 h, 48 h, 7 days, 14 days and 20 days postlesion. A significant effect on cGMP was found only at 48 h (-28%) and 7 days (-45%) postlesion. The results are discussed with respect to the cellular localization of cGMP and the hypothesized relationship of cGMP to cerebellar Purkinje cell activity.
