Recent evidence indicates that synchronized brain oscillations in the low gamma range (∼33 Hz) are involved in the perceptual integration of harmonic complex tones. At this rate, reaction times (RTs) are faster to targets that are not harmonically related to the prime. In the current study, we investigated the presence of this rate-specific inharmonic pop-out in groups of musicians and nonmusicians. We found that rather than increasing the salience of inharmonic targets, 33-pps priming reduced the salience of harmonic targets. This effect was observed in nonmusicians only, suggesting that music training reduces the role of oscillatory coding mechanisms in the perceptual integration of harmonic information.

The pitch of harmonic complex tones (HCT) common in speech, music and animal vocalizations plays a key role in the perceptual organization of sound. Unraveling the neural mechanisms of pitch perception requires animal models but little is known about complex pitch perception by animals, and some species appear to use different pitch mechanisms than humans. Here, we tested rabbits' ability to discriminate the fundamental frequency (F0) of HCTs with missing fundamentals using a behavioral paradigm inspired by foraging behavior in which rabbits learned to harness a spatial gradient in F0 to find the location of a virtual target within a room for a food reward. Rabbits were initially trained to discriminate HCTs with F0s in the range 400-800 Hz and with harmonics covering a wide frequency range (800-16,000 Hz), and then tested with stimuli differing either in spectral composition to test the role of harmonic resolvability (Experiment 1), or in F0 range (Experiment 2), or both F0 and spectral content (Experiment 3). Together, these experiments show that rabbits can discriminate HCTs over a wide F0 range (200-1600 Hz) encompassing the range of conspecific vocalizations, and can use either the spectral pattern of harmonics resolved by the cochlea for higher F0s or temporal envelope cues resulting from interaction between unresolved harmonics for lower F0s. The qualitative similarity of these results to human performance supports using rabbits as an animal model for studies of pitch mechanisms providing species differences in cochlear frequency selectivity and F0 range of vocalizations are taken into account.
