Neural activity from multiple fields can identify consonant sounds better when spike timing information is preserved. We ran the classifier using templates for all 7 sounds simultaneously to test the ability of neural activity to identify the 7 sounds with and without spike timing information. All four fields were significantly better at the identification task when spike timing information was preserved (black bars) than when spike timing information was removed (white bars; *P < 0.001). AAF was most affected by the removal of spike timing (i.e., had the greatest difference in performance across the two conditions), followed by A1, VAF, and PAF (P < 0.001).
