Figure 13.

Relationship between sequence-dependent differences in syllable phonology and RA activity. Phonological differences (COM distance) versus differences in RA neural activity (d′) at convergent (blue) and divergent (red) syllables. There is a significant, positive correlation between these quantities at both divergent (red; r = 0.56, p < 0.0001) and convergent (blue; r = 0.23, p < 0.0005) syllables. Values of d′ from multiunit recordings are plotted as circles, and single-unit recordings are plotted as squares.
