This study evaluated whether olfactory preconditioning is functional in newborn
rabbits and based on joined or independent memory of odorants. First, after
exposure to odorants A+B, the conditioning of A led to high responsiveness to
odorant B. Second, responsiveness to B persisted after amnesia of A. Third,
preconditioning was also functional with two overlapping pairs of odorants (A+B
and B+C) and amnesia of one odorant did not affect memory of the others. Thus,
incidental pairing of odorants allows reinforcement of one odorant to implicitly
reinforce the others, the bond then vanishes, and the memory of each element
