“…In a broad sense, the current study deepens our understanding of the neural processing of audiovisual signals in natural stimuli with complex temporal structures. Cortical entrainment can track simple rhythmic stimuli like tone sequences or luminance-varying patches (C. Keitel et al, 2017; Yuan et al, 2021) as well as complex rhythmic structures in speech (Brookshire et al, 2017; Ding et al, 2016; Keitel et al, 2018) and BM (Shen, Lu, Yuan, et al, 2023). Beyond unisensory processing, cortical entrainment also plays a role in the multisensory processing of simple or discrete rhythmic signals generated by physical stimulation (Bauer et al, 2021; Miller et al, 2013; Nozaradan et al, 2012b; Simon & Wallace, 2017).…”
