Infusing ACh bilaterally into the LC during an odor presentation results in neonatal pups acquiring a subsequent preference for that odor. This results in the LC releasing NE. The effect of the LC infusion can be blocked by injecting pups systemically with propranolol prior to the LC infusion (Sullivan et al., 2000b).
