Figure 6. Infralimbic but not Prelimbic NaB Infusions Caused Persistent Extinction Enhancements.
A) During retrieval mice receiving NaB into the infralimbic (n=6) or prelimbic cortex (n=3) following extinction did not differ from vehicle (n=9). Only the mice injected with NaB following extinction froze significantly less than vehicle on the 1 and 14D tests. B) Cannula placements with a representative angled placement in the infralimbic cortex (inset). Stereotaxic image reproduced with permission from [26].
