| Popis: | International audience; Specialised brain structures allow songbirds to process acoustic signals. One of these brain areas, the NCM (caudomedial neostriatum), shows an immediate-early gene ZENK response when a bird hears a conspecific song. Using a neuro-ethological approach, we investigate if high level of background noise added to conspecific song can modify this song-induced genic activation. We test the ZENK activation in the NCM of adult male Zebra finches Taeniopygya guttata (n = 17) by playing back conspecific signals mixed with different levels of noise, the successful discrimination being reflected by the birds' (n = 6) behavioural responses to these stimuli. From our results, it appears that a high genic activation of the NCM does not necessarily require the audition of an undegraded species-specific signal. Nevertheless, it requires that the signal still contains sufficient information to elicit a behavioural response. The genic activation of the NCM remains thus stable against very high levels of a wide-band background noise, as far as the signal recognition remains possible for the bird. |
