Animals need to recognize the sounds of their species regardless of volume, but neurons can only signal over a limited range. In this paper, Allison and I asked how songbird auditory neurons adapt to the volume of incoming sounds. We found that these neurons represent sound differently when its average intensity changes, and when the range of instentiies changes. These adaptation are very reminiscent of the way visual neurons adapt to different ranges of light. This suggests that the brain uses similar strategies to deal with both types of signals.
In this paper I did some more stuff.
