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 For binary (spike train) signals, take FFT of signal or autocorrelation of signal?
(not trying to be an overbearing curmudgeon here, just offering some constructive criticism. I'm happy to see a methods question on here!)

Otherwise, this is really just an exercise in signal processing, to be frank.

I'm using "information" as a loaded term. I was referring to both measures that you are talking about, sorry if that wasn't clear. Neither is going to tell you anything meaningful. If you're locking to a specific event (sensory input or specific motor output - e.g., an EMG of a muscle) the frequency variation will tell you something, but a "free form" recording really isn't. You'd be better off examining local field potentials (most extracellular recording systems can separate these out in the spike sorting processing) if you are trying to tease out frequency changes.

As an aside, for papers to look at, George Gertstein is the guru of the analysis of spike trains.

What is your ultimate objective with "characterizing" the data? Definitely read Spikes when you have a chance. The short answer from there is that it depends on what you are looking to get out of the signal. If you're looking to drive a device or something of that nature, the FFT is going to be computationally burdensome, and may not give you sufficient information.

Wow, it must have been an honor to work with him. Thank you for sharing the reference. We'd love to have you stick around and lend your expertise!

comment Why do many people play Candy Crush without ever buying anything while some spend all their money on it?
I think there's some interesting questions buried in the 99 cent price point used for most of the add-ons/additional moves purchases. There are a few questions on the site about those factors as well.

I think it's an interesting question, I know there's been a lot of work done on it, I just don't have any references handy.

I've modified your title to ask about what you are actually after. Seeking the "best" addiction studies is not really answerable and is too broad.

Check into organizations like qps-nl.com/earlystage_subject.html that actively recruit for those running studies.

(but as to your main question, no, no one is likely to let you just get scanned for kicks, there are liability issues)

comment Getting analysis of changes in MY brain upon cannabis consumption
I don't really see a question here. For a researcher that's studying aspects of "cannabis consumption", I'm sure they'd be happy to have you as long as you didn't fall under any of the exclusion criteria. For this type of study recruitment, check in the newspaper of cities that have a well-known teaching hospital.
