comment how is tone volume encoded?
@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 :)

comment how is tone volume encoded?
@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...

Maybe I should also add that my main area of interest is sensory adaptation, so that is my starting point in asking this question: why does adaptation lead to differences in perceptual aftereffects across the two modalities.

comment aftereffects of auditory adaptation
Thanks for your input! I was indeed thinking about auditory hallucinations as well. They prove that there is such a thing as an auditory percept in the absence of a stimulus. But that makes me even more curious about the absence of auditory aftereffects, whereas visual afterimages can be quite strong and clear.

comment Why do dreams lose clarity quickly over time after we awaken?
In case I don't manage to find the time to dig up the reference (I have it somewhere on an external disk, no idea who the authors are): a neurotransmitter that is crucial for transforming short-term into long-term memories is inactive in the hippocampus during sleep. Interestingly, HM, a patient who couldn't achieve long-term memories due to an operation when both hippocampi were removed, described his state as constantly waking from a dream.

comment Diffrence between SSVEP and P300
Interesting stuff! I have indeed also come across some papers where the steady-state response is modulated by top-down factors, so it appears not to be purely stimulus-driven. And a lot of new research shows attention and expectation modulation of sensory components that are quite early. I just have the impression that the consensus is that these modulations are surprising for the SSVEP/AEP, while they are a given for the P3. In fact I don't even know if there is any discernible P3 component in the absence of top-down effects?
