FIGURE 2.5

Illustration showing that nonassociative freezing to the tone cue can be reduced by preexposure to the tone in the unpaired group. Both groups had equal exposure to the tone cue, but mice in the unpaired group received tone exposure on the day prior to the foot shock conditioning. In the context test, mice trained with paired tone or unpaired tone showed similar freezing times. However, in the cue test, the paired group showed increased freezing to the tone.
