the results suggest that type i benzodiazepine binding sites in the nigra are located on kainic acid-sensitive elements ( probably intrinsic neurones ) , while type ii benzodiazepine binding sites , the number of which increased after degeneration of the striato-nigral pathway , are localized on kainic acid-resistant structures ( probably axons or terminals ) that receive an input from striatal afferents and from interneurones in the nigra .
