Topic: speech-FFR

Selective attention allows us to focus on relevant information while filtering out distracting signals. Research on the neural mechanisms of selective attention to speech has primarily explored low-frequency responses to amplitude modulations in the auditory cortex. EEG studies revealed, in addition, attentional modulation of subcortical neural responses at the fundamental frequency of speech (speech-FFR). Recent MEG studies have identified cortical contributions to the speech-FFR (Coffey et al. (2017), Kulasingham et al. (2020), Schüller et al. (2024)), but it remains unclear if these cortica

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 musi

In natural speech, the harmonic pattern of a speaker’s fundamental frequency (f0) and its higher harmonics elicits a neural response at the fundamental frequency which can be captured by electroencephalography (EEG) or magnetoencephalography (MEG), termed speech-FFR. While EEG measurements have found a subcortically evoked early neural activity to this speech-FFR, MEG studies have recently emphasized involvement of cortical sources as well. Here, we focused on disentangling the sources of the neural response at the fundamental frequency of speech using EEG-based source localization. We theref
