Receptor binding studies of the substantia nigra (SN) and cerebellum revealed two affinity sites for muscimol binding in the SN and cerebellum of adult and 16-day-old rats. Scatchard analysis revealed a paucity of high-affinity muscimol receptors in the SN of 16-day-old rat pups. These results suggest that the lack of anticonvulsant action of muscimol in the SN of 16-day-old rat pups may be due to the paucity of high-affinity muscimol receptors as compared to adult rats.
