“…Neural entrainment has been proposed as the neural correlate underlying the perception of musical rhythm ( Large et al, 2015 ; Weineck et al, 2022 ). Neural entrainment reflects the selective attention to the external environment and ensures optimal event processing ( Helfrich et al, 2019 ; Obleser and Kayser, 2019 ; Kachlicka et al, 2022 ). In line with our expectations, patients with DoC demonstrated the ability to track music, indicating their preserved cortical ability to track music.…”

“…Musical rhythms occur in a particular frequency range corresponding to the delta and theta frequency bands ( London, 2004 ; Large et al, 2015 ), the perception of which can be achieved through the entrainment of delta and theta endogenous oscillations in the brain during music listening. Low-frequency entrainment offers a method for temporal integration of information and selective attention ( Lakatos et al, 2008 , 2019 ; Kachlicka et al, 2022 ; Nandi et al, 2023 ), while gamma oscillations are related to predictive mechanisms and underpin fine-grained sensory processing ( Fries et al, 2007 ; Fries, 2009 ; Herff et al, 2020 ; Parto-Dezfouli et al, 2023 ). For example, a previous study reported that the gamma oscillation predicted the next tone onset ( Snyder and Large, 2005 ).…”

ObjectiveThis study aimed to determine whether patients with disorders of consciousness (DoC) could experience neural entrainment to individualized music, which explored the cross-modal influences of music on patients with DoC through phase-amplitude coupling (PAC). Furthermore, the study assessed the efficacy of individualized music or preferred music (PM) versus relaxing music (RM) in impacting patient outcomes, and examined the role of cross-modal influences in determining these outcomes.MethodsThirty-two patients with DoC [17 with vegetative state/unresponsive wakefulness syndrome (VS/UWS) and 15 with minimally conscious state (MCS)], alongside 16 healthy controls (HCs), were recruited for this study. Neural activities in the frontal–parietal network were recorded using scalp electroencephalography (EEG) during baseline (BL), RM and PM. Cerebral-acoustic coherence (CACoh) was explored to investigate participants’ abilitiy to track music, meanwhile, the phase-amplitude coupling (PAC) was utilized to evaluate the cross-modal influences of music. Three months post-intervention, the outcomes of patients with DoC were followed up using the Coma Recovery Scale-Revised (CRS-R).ResultsHCs and patients with MCS showed higher CACoh compared to VS/UWS patients within musical pulse frequency (p = 0.016, p = 0.045; p < 0.001, p = 0.048, for RM and PM, respectively, following Bonferroni correction). Only theta-gamma PAC demonstrated a significant interaction effect between groups and music conditions (F(2,44) = 2.685, p = 0.036). For HCs, the theta-gamma PAC in the frontal–parietal network was stronger in the PM condition compared to the RM (p = 0.016) and BL condition (p < 0.001). For patients with MCS, the theta-gamma PAC was stronger in the PM than in the BL (p = 0.040), while no difference was observed among the three music conditions in patients with VS/UWS. Additionally, we found that MCS patients who showed improved outcomes after 3 months exhibited evident neural responses to preferred music (p = 0.019). Furthermore, the ratio of theta-gamma coupling changes in PM relative to BL could predict clinical outcomes in MCS patients (r = 0.992, p < 0.001).ConclusionIndividualized music may serve as a potential therapeutic method for patients with DoC through cross-modal influences, which rely on enhanced theta-gamma PAC within the consciousness-related network.
