Figure 5.

Onset response latencies on lateral superior temporal gyrus (STG) are shorter than in anterolateral Heschl's gyrus (HG). A: Data from a representative subject. Left: location of recording contacts in the superior temporal plane (top) and over perisylvian cortex (bottom). Right: High gamma event‐related band power (ERBP) recorded from eight representative sites (a through h) in response to speech syllable /da/. Thick lines and gray shading correspond to cross‐trial mean ERBP and its 95% confidence interval, respectively. Arrows indicate measured high gamma onset response latency. B: Model predictions of onset response latencies to the syllable /da/ in HG (top) and lateral STG (bottom). FreeSurfer template brain is shown on the left. Predictions are based on data from 11 subjects and are bound by the convex envelopes of locations of responsive cortical sites. Modified from Nourski et al.22
