Abstract

Previous research indicated that neural responses to acoustic signals can differ in musicians and non-musicians. For instance, subcortical responses to speech sounds are stronger in musicians (Anderson et al. 2012). These neural responses include the frequency-following response at the fundamental frequency of the speech signal (speech-FFR). However, the speech-FFR also includes a cortical contribution with potential dependence on musical experience which is not yet known.We measured the cortical contribution to the speech-FFR via MEG recordings in 42 participants with different levels of musical experience. Participants were simultaneously presented with two audiobooks from different speakers, selectively attending one while ignoring the other. The data was analyzed by computing temporal response functions (TRFs) for the source-reconstructed activity in the auditory cortex, for two acoustic features of the speech stimuli related to the fundamental frequency and thus described the speech-FFR.Our data showed a significant attentional difference for both acoustic features, comparable to our previous findings (Schüller et al., J. Neurosci. 43:7429, 2023). However, we did not find that the responses were modulated by musical training. Musicians and non-musicians had comparable cortical contributions to the speech-FFRs for both mean and variance of the distributions. In addition, the mentioned attentional modulation was not influenced by musical training. Contrary to the findings for the subcortical contribution, the cortical response at the fundamental frequency of speech does not appear to be influenced by musical training. However, more work is needed to understand the interplay with the subcortical response and the possible impact of selective attention.
