Figure 7.
(A) Oscillogram and sonagram of composite no. 5 (fSFM-bUFM), the best composite for unit no. 102 (FM1–FM3, BD = 8.1 ms). (B) PSTH shows unit’s robust response to the original composite (fSFM-bUFM; response ratio = 1108%). (C) Unit almost failed to respond to the first syllable (fSFM). (D) Unit nearly failed to respond to the second syllable (bUFM). (E) No response to playback of the reversed composite. (F) Unit’s response decreased dramatically and eventually ceased when a silent period ≥0.5 ms was inserted between the two components of composite fSFM-bUFM.
