Role of Auditory Feedback in the Bengalese Finch Animal Model
Learned forms of vocal communication, such as human speech and birdsong, rely on auditory experience for their acquisition, refinement and maintenance. This dependence is most evident when sensory feedback is lost, as both speech and song rapidly deteriorate following deafening. Notably, the Bengalese finches studied here are the most dependent on auditory feedback of any songbird studied to date. We altered the feedback experience d during singing by changing the composition of the atmosphere in which birds sang. Previous studies indicated that replacing air with a helium/oxygen mixture elevated ...
