Responses to CV syllables from the dominant (left) hemisphere in a representative subject (L178). A: Location of the 96-contact subdural grid. B: AEP and high gamma ERBP recorded from two exemplary sites (X and Y, location marked in panel A) in response to syllables /pa/, /ba/, and /da/. C, D: Cortical activation maps showing AEP and high gamma ERBP (C and D, respectively), elicited by the three CV syllables (rows) and averaged within 50 ms consecutive time windows (columns).
