A mechanism for the cortical computation of hierarchical linguistic structure
Fig 3
Grammatical sentences: DORA network power spectrum compared to human cortical oscillations.
The solid line represents cortical power while participants listened to four syllable/word sentences played over 1 s in Ding et al. [6]. Power increases are evident at the 1 Hz (sentence duration), 2 Hz (phrase duration), and 4 Hz (word duration) range. The dashed line depicts firing in DORA while processing the same sentences used in Ding et al. Units in DORA fire for the duration of the sentence, at intervals of half the length of the sentence and at intervals lasting a quarter of the length of the sentence. Data from the stimulation and the code to run it are available at https://osf.io/eb2vp/ and https://github.com/AlexDoumas/dingetal_sent.
