摘要
These experiments were performed to test the hypothesis that a region associated with the trigeminal nuclear complex is selectively involved in mediating the classically conditioned nictitating membrane reflex in the rabbit. Microinjections of Lidocaine were used to produce a temporary, localized block of neural activity following the conditioning of the reflex using a standard tone/air puff-paired stimulus paradigm. Data indicate that the injection of Lidocaine at the medial pars oralis/reticular formation junction results in a selective suppression of the conditioned reflex.
