Figure 13.

Periodicity-tagged firing rate plotted as a function of unit BF for responses to the /a/ and /i/ components of the double vowels /a, i/ (125, 100) and /a, i/ (250, 200). (A–D) Static F0 vowels. (E–H) Modulated F0 vowels. Top row anechoic conditions. Second row mild reverberation. Third row moderate reverberation. Bottom row strong reverberation. (A–H) Red symbols indicate responses to the /a/ component. Blue symbols indicate responses to the /i/ component. Solid lines indicate lowess fits to the data, to demonstrate the trend across BF. Note these trend lines include responses from all unit types.
