Sir Charles Scott Sherrington is one of my science heroes, so I'm featuring him on my cogsci profile. He is often credited with coining the word "synapse."

comment Is there a better way to describe brain activity than EEG “brain waves”
Another stupendous answer from you! Thanks for lending us your expertise :)

comment Is there a better way to describe brain activity than EEG “brain waves”
I don't disagree with you, I just don't think that's how the term is normally used. Originally, I interpreted the question to be "Is the 'brain waves' interpretation of EEG (that is the frequency bands, etc.) outdated?" I hadn't considered your point of view (which is equally if not more valid) that he was asking "Are there different methodologies that also offer an insight into brain activity as a whole?", as yours accounts for the latter, but in my opinion doesn't address the former. Anyway, I wasn't trying to put your answer down, just the opposite.

Yes, I know, I did extracellular recording for a number of years, but I think it's just a semantic difference, I personally would not refer to a spike to be a "brainwave". I would reserve that for the aggregate activity.

It's very difficult to discern spiking information within the ensembles using EEG, though. Even if you're talking about using extracellular microelectrodes, the "brain waves" are more the local field potentials and not spikes. That said, I do like the answer in terms of a different interpretation of the main question in the title.

@H.Muster I was leaving some of that for you! Yes, I suppose that one of the two of us should cover ERS/ERD. I had thought of that as being more "traditional", but I think you are right.

comment Is there any fMRI evidence for different “states of mind”?
Drives in general can have an effect on drug seeking behaviors in humans and animals. A familiar smell of an old haunt or other cues can cause addicts to recidivate. I don't have any literature handy, but this is often associated with the nucleus accumbens.

I will try to flesh a bit more of this out later, but it should give you a head start.

comment 'Model-free' learning in humans
It is a question, and at its root is a very interesting one, but at this point it is very broad. I don't want to speak for anyone, but I think the others are trying to say that now that you know the terminology, we have "answered" this particular question, so if you use that information to make the question more specific to what you want to know, it will be stronger. FWIW, I'm glad to see you back again as I think you do ask great/interesting questions, this one just needs a bit of tuning and specificity to it.
