d-cycloserine in the basolateral amygdala prevents extinction and enhances reconsolidation of odor-reward associative learning in rats

► Pre-extinction DCS in the BLA impairs extinction of appetitive odor discrimination. ► The same treatment before brief memory reactivation improves task reconsolidation. ► BLA NMDA receptors are involved in odor-food reward associative learning & memory. ► DCS in BLA may potentiate the persistence or strength of the original memory trace.
