Effects of ventral hippocampus inhibition may be selective to contingency degradation. (A) To determine if inhibition of the ventral hippocampus prevented the use of cues to guide behavior, a subset of animals expressing the Gi-DREADD in the ventral hippocampus underwent Pavlovian conditioning in which a cue predicted sucrose delivery. Administration of CNO did impact the expression of cue-guided consummatory behavior. (B) Inhibition of the ventral hippocampus did not impact the acquisition of extinction of sucrose seeking.
