Figure 4.
Spectral profile of ERBP during picture (left) and voice naming (right) of proper nouns in pFG, STG, and ATL averaged across all subjects. Thick lines and shaded areas represent mean ERBP across ECoG frequencies and its 95% confidence interval, respectively. Second x-axis shows conventional ECoG frequency bands [theta (θ), 4–8 Hz; alpha (α), 8–14 Hz; beta (β), 14–30 Hz; gamma (γ), 30–70 Hz; high gamma (γhigh), 70–150 Hz]. ECoG frequency ranges that correspond to ERBP increases beyond the lower limit of the 95% confidence interval are shown as horizontal color bars.
