Brain rhythms readily synchronize with auditory rhythms, like those in music and speech. Although brain–environment synchrony is associated with positive behavioral outcomes – we better understand and remember material when brain–environment synchrony is tighter – we’re missing an understanding of why one person might succeed in a listening situation while another might fail. The Research Group Neural and Environmental Rhythms takes a dynamical-systems approach to understanding brain–environment synchrony, conceptualizing and modeling brain rhythms as being generated by neural oscillators (and testing that assumption along the way). We combine individual-differences, experimental, and lifespan (later half for now) approaches, and make use of psychophysics, electrophysiology (M/EEG), and modeling to move towards a more wholistic, mechanistic understanding of brain–environment synchrony and its role in auditory perception.
