It remains controversial, however, whether such envelope-tracking neural activity reflects entrainment of neural oscillations or superposition of transient responses evoked by sound features. Recently, it is suggested that the phase of envelope-tracking activity can potentially distinguish entrained oscillations and evoked responses. Here, we analyze the phase of envelope-tracking in humans during passive listening, and observe that the phase lag between cortical activity and speech envelope tends to change linearly across frequency in the θ band (4{\textendash}8 Hz), suggesting that the θ-band envelope-tracking activity can be readily modeled by evoked responses.}, URL = {https://www.eneuro.org/content/8/4/ENEURO.0058-21.2021}, eprint = {https://www.eneuro.org/content/8/4/ENEURO.0058-21.2021.full.pdf}, journal = {eNeuro} }
