| Nov 18, 2014 at 22:04 | comment | added | Ana | @ChuckSherrington - yeah, I've been thinking about that as well. Feedback connections in a predictive coding type framework would explain sound level adaptation well - if louder tones recruit a new group of neurons. It it's the same neuronal population, I have something interesting to muse about :) | |
| Nov 18, 2014 at 22:00 | comment | added | Chuck Sherrington | There are going to be a lot of projections in the other direction from A1 to the MGN as well, which would be fascinating to study in that regard. I wish I had a ready answer for you, but we'll see if anyone can come up with one. | |
| Nov 18, 2014 at 21:55 | comment | added | Ana | @ChuckSherrington, I am actually curious because I recently read about sound level adaptation in the auditory nerve, inferior colliculus and medial geniculate body. Sound level adaptation is the following: when a sound is played equiprobably at different volumes, neural activity scales with the volume. But if one of the volumes is more frequent than others, neural activity to that volume will dampen. Now I'm wondering whether a whole new set of neurons is recruited with a change in volume, or not. Given that it was found on the auditory nerve (albeit weakly), probably not. But still... | |

I think the answer is going to lie in the association cortices, since this is as much a tactile and proprioceptive issue as it is an auditory one. That's just a gut feeling, but there must be literature on this somewhere. | |
