Effect of PKMζ inhibition in the amygdala on olfactory-mediated fear potentiated startle. Rats were infused with ZIP (10nmol/µl, .5µl/side) or saline into the amygdala 2 hours or 2 days (a) before a memory test. (b) Nissl stained images (2x magnification) showing representative placements in rats infused with saline or ZIP. The bottom panel shows a 4x view of the amygdala in a saline and ZIP infused rat. No obvious signs of toxicity were observed. (c) Rats infused with ZIP (n=11) showed significantly less (p< .05, t–test) fear potentiated startle than controls (n=9) when tested 2 hours (c, left side) or 2 days (ZIP, n=15; SAL, n=14) (c, right side) after infusion. These and the subsequent graphs show means +/− SEM.
