That's an interesting point, thanks!

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?

comment How does the frequency of a visual stimulus affect the steady-state visually evoked potential?
The refresh rate is the rate at which the image on your screen gets renewed. I think that for most monitors it's 60 Hz. But it's often more complicated than that, because screens often don't refresh the entire image at once (e.g. they might do it line by line, or odd vs. even lines, or center to surround). But some of this flicker would probably be visible in the neural response. I'm not too sure about that though, maybe it's too subtle to be registered as neural activity.

comment How does the frequency of a visual stimulus affect the steady-state visually evoked potential?
By amplitude modulation I mean this. In this picture the carrier signal is the frequency of the tone, whereas the modulating sine wave signal is what I call amplitude modulation. The result is an amplitude modulated signal: it's a tone of a given pitch, that gets louder and softer at the frequency of the modulating sine wave signal. This frequency should also be visible in the neural response.
