Effects of odor (CS) paired with local injections of OA (US) into MB calyces or antennal lobe on %PER during three consecutive test trials 30, 40, and 50 min after injection. Odor paired with OA (OpA) or saline (SpA) or unpaired with OA (OupA) or saline (SupA) injected into the antennal lobe and an unsuccessfully injected control group (mInj), and two parallel groups with odor paired (OpC) or unpaired (OupC) with OA injected into the MB calyces. The OA paired groups show an increased level of %PER. (n) The number of subjects per group that survived throughout experiments, showed LY restricted to the injected neuropil, and gave a sucrose-evoked PER after the last test.
