“…Declaring the existence of neural entrainment phenomena must be approached with caution because many apparent oscillatory phenomena can be due to other factors (Haegens and Golumbic, 2018;Gourévitch et al, 2020;Obleser and Kayser, 2019). Haegens and Zion Golumbic propose three stringent criteria.…”

“…Although rhythmic oscillations appear to be ubiquitous in the auditory system (Neymotin et al, 2020;Gourévitch et al, 2020), it is unclear whether such responses represent merely the summation of evoked responses to periodic sound elements, or arise from truly oscillatory intrinsic properties of the auditory system (Obleser and Kayser, 2019). The distinction is important to understanding their function (Gourévitch et al, 2020;Haegens and Golumbic, 2018), and fits into a bigger picture concerning the roles of intrinsic oscillations throughout the brain, in which they appear to play a role coordinating neuronal and network activity to support complex cognitive processes (Buzsáki and Draguhn, 2004;Thut et al, 2012).…”

“…Finding positive results, we conducted a new MEG experiment to test whether a preceding stimulus affects the brain's representation of an incoming stimulus. Our approach avoids the pitfalls of analysis which may produce artifactual oscillations (Gourévitch et al, 2020). Moreover, MEG allows for separation of cortical and subcortical sources of the FFR (Coffey et al, 2016) such that we can test whether these phenomena can be observed at all levels of the auditory system or not, which the existing literature does not address.…”

Oscillatory Entrainment of the Frequency-following Response in Auditory Cortical and Subcortical Structures

There is much debate about the existence and function of neural oscillatory entrainment mechanisms in the auditory system. The frequency-following response (FFR) is an index of neural periodicity encoding that can provide a vehicle to study entrainment in frequency ranges relevant to speech and music processing. Criteria for entrainment include the presence of post-stimulus oscillations and phase alignment between stimulus and endogenous activity. To test the hypothesis of entrainment, in experiment 1 we collected FFR data to a repeated syllable using magneto-(MEG) and electroencephalography in 20 healthy adults. We observed significant oscillatory activity after stimulus offset in auditory cortex and subcortical auditory nuclei, consistent with entrainment. In these structures the FFR fundamental frequency converged from a lower value over 100 ms to the stimulus frequency, consistent with phase alignment, and diverged to a lower value after offset, consistent with relaxation to a preferred frequency. In experiment 2, we tested how transitions between stimulus frequencies affected the MEG-FFR to a train of pure-tone pairs in 30 adults. We found that the FFR was affected by the frequency of the preceding tone for up to 40 ms at subcortical levels, and even longer durations at cortical levels. Our results suggest that oscillatory entrainment may be an integral part of periodic sound representation throughout the auditory neuraxis. The functional role of this mechanism is unknown, but it could serve as a fine-scale temporal predictor for frequency information, enhancing stability and reducing susceptibility to degradation that could be useful in real-life noisy environments.

“…Entrainment in lower frequency ranges (i.e. delta, theta bands) has been proposed as a mechanism during active stimulus processing, for example to define the parsing window of linguistic segments from continuous speech (Kösem et al, 2018;Gourévitch et al, 2020). The FFR is an evoked response to a periodic signal, but it is not known whether there is some advantage to an oscillatory representation as opposed to a veridical feed-forward one.…”

“…A low-level prediction mechanism that could rapidly generate error signals when stimulus periodicity changes could be useful, because encoding rapid changes in auditory information is critically important in complex sound processing, as in speech or music. Future work is needed to determine whether differences between incoming information and the FFR oscillatory entrainment produce brain responses consistent with predictive coding signals (Gourévitch et al, 2020;Chao et al, 2018).…”
