Learning of a particularly difficult olfactory-discrimination (OD) task results in acquisition of rule learning. This enhancement in learning capability is accompanied by the long-term enhancement of synaptic connectivity between piriform cortex pyramidal neurons. In this study we examined whether olfactory rule learning would modify the predisposition to induce long-term potentiation (LTP) in the pathway projecting from the piriform cortex to the olfactory bulb. We report that OD learning was associated with enhancement in the predisposition to induce LTP. This learning-related effect may be affected by process generation of new granule cells located in the olfactory bulb.
