“…Oscillatory activity of the brain, and the mechanisms of entrainment (to a stationary external stimulus) and phase re-setting (to an incoming stimulus) are crucial to both cognition and language (Giraud & Poeppel, 2012). Various frequencies of human brain activity, including delta (~2 Hz), theta (4 Hz), and gamma (<30 Hz), have been implicated in linguistic processing (Gross et al, 2013), which proceeds on multiple timescales simultaneously-compare, for example, the <1 Hz envelope of intonation versus~4 Hz envelope of syllabic parsing (Blumenthal-Dramé & Malaia, 2018). However, multiple studies of intelligibility parameters indicate that the temporal granularity of 4 Hz is crucial to syllabic parsing, which appears to be an indispensable step in language comprehension.…”
