Extended Data Fig. 2: Naturalistic speech production task performance and phonetic selectivity across neurons and participants.
From: Single-neuronal elements of speech production in humans
a. A priming-based speech production task that provided participants with pictorial representations of naturalistic events and that had to be verbally described in specific order. The task trial example is given here for illustrative purposes (created with BioRender.com). b. Mean word production times across participants and their standard deviation of the mean. The blue bars and dots represent performances for the five participants in which recordings were acquired (n = 964, 1252, 406, 836, 805 words, respectively). The grey bar and dots represent healthy control (n = 1534 words). c. Percentage of modulated neurons that responded selectively to specific planned phonemes across participants. All participants possessed neurons that responded to various phonetic features (one-sided χ2 = 10.7, 6.9, 7.4, 0.5 and 1.3, p = 0.22, 0.44, 0.49, 0.97, 0.86, for participants 1–5, respectively).
