Abstract Rhythmic entrainment echoes – rhythmic brain responses that outlast stimulation can evidence endogenous neural oscillations entrained by the stimulus rhythm. We here tested for such in auditory perception. Participants detected a pure tone target, presented at variable delay after another was rhythmically modulated amplitude. In four experiments involving 154 participants, we (1) which rate produces strongest echo and (2) inspired audition’s tonotopical organisation findings non-human primates whether these are organized according to sound frequency. found 6-Hz 8-Hz stimulation, respectively. Best moments target detection (in or anti-phase with preceding rhythm) depended on frequencies of entraining stimuli matched, line organisation. However, same experimental condition, best were not always consistent across experiments. provide speculative explanation differences relies notion repetition-related adaptation might exercise competing, opposite influences Together, find perception seem more complex than those predicted from initial theories entrainment.

Rhythmic entrainment echoes-rhythmic brain responses that outlast rhythmic stimulation-can demonstrate endogenous neural oscillations entrained by the stimulus rhythm. Here, we tested for such echoes in auditory perception. Participants detected a pure tone target, presented at variable delay after another was rhythmically modulated amplitude. In four experiments involving 154 human (female and male) participants, (1) which rate produces strongest echo and, inspired tonotopical organization of system findings nonhuman primates, (2) whether these are organized according to sound frequency. We found 6 8 Hz stimulation, respectively. The best moments target detection (in phase or antiphase with preceding rhythm) depended on frequencies entraining stimuli matched, is line organization. However, same experimental condition, were not always consistent across experiments. provide speculative explanation differences relies notion repetition-related adaptation might exercise competing opposite influences Together, find perception seem more complex than those predicted from initial theories entrainment.
