Previously acquired aversive and appetitive memories are not stable and permanent. The reactivation of such memories by re-exposure to training stimuli renders them vulnerable to disruption by amnestic agents such as the noncompetitive N-methyl-D-aspartate receptor antagonist (+)-5-methyl-10,11-dihydro-SH-dibenzo{a,d}cyclohepten-5,10-imine maleate (MK-801). However, relatively little is known about the parameters that influence the reactivation process. Here, we show that the method of stimulus… CONTINUE READING
