Figure 4: A: Experimental set up for recording local field potentials of the primary auditory cortex (AI) in the awake monkey. B: Responses to / da/-/ta/ syllables with variable VOT. Consonant release (blue arrow) evoked robust transient response at any VOT examined (0, 20, 40, 60 ms; depicted in the left). In contrast, voicing onset (red arrow) evoked robust response only if VOT was long enough (40, 60 ms). Accordingly, the signals producing /ta/ percept led to “double-onset responses”; the signals producing /da/ percept led to only “single-onset responses” (Modified from Steinschneider et al. [45]).
