Hearing the song in noise

Event Abstract Back to Event Hearing the song in noise Moore Richard1*, Patrick R. Gill2 and Frederic E. Theunissen3 1 University of California, United States 2 Cornell University, United States 3 University of California at Berkeley, Department of Psychology, United States One major task of the auditory system is to pick out and process relevant sounds against a background of noise. Some degree of background rejection can be achieved by having cells tuned selectively for properties found in sounds of interest but not present in background noise. This scheme fails, however, to separate a relevant sound from a background of like sounds. We therefore propose that more complicated mechanisms may be at work. We recorded from auditory fields L and NCM in urethane-anaesthetized zebra finches while playing zebra-finch songs and modulation-limited noise. We presented each stimulus alone, and we also combined each song with several different noise stimuli. This resulted in three conditions: noise alone; song alone; and song plus noise. We compared the PSTH for the combined trials with the respective PSTHs for each stimulus alone. We also computed receptive fields (STRFs) from the noise-alone and song-alone trials, and compared the predicted response to the combined stimuli with our observed result. In both cases, we found that responses to sounds masked by noise were better predicted by song-alone responses, indicating that these areas employ a more complex form of stream segregation than matched filters.
