Research on memory reconsolidation has relied heavily on the use of Pavlovian auditory cued-fear conditioning. Here, an auditory cue (CS) is paired with a footshock (US) and the CS is later able to evoke a freezing response when presented alone. Some treatments, when administered to conditioned subjects immediately following a CS-alone (memory reactivation) trial, can attenuate the freezing they display on subsequent CS-alone (test) trials, in the absence of the treatment. This reduction in...
