The frequency-following response (FFR) is a phase-locked evoked response recorded at the scalp that directly mirrors the frequency content of acoustic stimuli. While once believed to be primarily of subcortical origin, MEG and EEG research has more recently shown that the FFR originates from multiple subcortical and cortical neural sources (Coffey et al., 2016; Hartmann and Weisz, 2019; Tichko and Skoe, 2017). The present study tests whether the frequency of the stimulus can be reliably decoded from frequency-specific power of single-trial high-density EEG, despite the extremely small amplitude of the FFR relative to the background EEG. Since the amplitude of the FFR contributions from the multiple constituent cortical and subcortical sources can be modulated independently, it is reasonable to posit that the scalp distribution of the FFR may be malleable to psychological processes such as selective attention. Past studies on the attentional modulation of the FFR have been inconclusive (e.g., Forte et al., 2017; Hoormann etal., 2004). We therefore also examine the accuracy of the single- trial FFR-based decoding as a function of different attention manipulations.
