Or sometimes you get drift, and then you don't remember a smell, and this happens all the time - which is why if we re-smell something, we don't necessarily hit the same neurons, but we also remember old smells, because those didn't drift. Or is that excluded by the experiment?
- michaelerule 5y agoMy understanding was that these experiments didn't completely rule out the possibility of a stable sub-population. Also, the olfactory bulb projects to other areas besides piriform, and those might support long-term stability. My extremely speculative unfounded conjecture is that piriform is actually a novelty encoder, and plays a role in encoding new memories in a changing environment. But, I think the data don't quite support this at this time.
