devoting 4 years to studying general cell biology...

I am starting to wonder if I should just go where the researchers and theorists are, 'cause that's what I'd like to get into, real pushing-the-boundaries-of-our-knowledge stuff.

I know what you mean. I think cell biology is pretty important to neuroscience, since most of the information is at the 'sub organ of a cell' level. Systems neuroscience is a lot of fun, but it seems to be mostly synthesized information gained from dealing with the cellular level.
I have a friend who's an fMRI specialist, though, and I don't think he's really done all that much cell biology. Lots of math & physics & programming, I think.
Where do you publish the results of your research? I often hear that professors publish their works in peer reviewed journals but I have never read one of these journals before.
There are a LOT of journals. There's a bit of a prestige system for journals, some of that prestige system is artificially generated and some is due to being deserved. Go to '
pubmed' and type in a search term. Each of those hits are from an article. If you click on the link, you'll have access to the name of the journal.
You don't see these journals in the supermarket because they wouldn't sell there. That's actually very sad. A huge number of articles are free online, and you should be able to access most of them from a university library
Are your published works just a brief overview about what your research entails or do they contain large amounts of data and information about the experiments and trials that you performed?
It's a bried overview of the techniques, because so many techniques are standardized. If there's a new technique, there's more detail.
The language tends to be
very specific. The peer review process tries to ensure that you never claim more than you actually show. A great deal of information will be summarized using statistics and pictures. You won't see the results for each lab rat, but you'll see statistics for each test group. There's also an attempt to clearly distinguish between 'facts' and 'theory' ('results' and 'discussion') but I honestly prefer when they include a bit of theory in their results section to justify why they're doing each experiment.
Often a lab will publish something called a "Review article", a specific paper tends to examine
one scientific point at a time. A review article creates a synthesis. In the pubmed link, there's a search tab which specifies for review articles.
What exactly does it mean when a journal is 'peer reviewed' (do other scientists try to duplicate the results of your experiments to verify them?)
I've now informally been part of the peer review process. It's
gads of fun. Basically, you read their initial paper and you try to tear it apart. You examine each of their conclusions. You examine their statistics. You see if the techniques they use answer the questions they're asking.
To peer review, you need to be an established expert in a field (I am not, but a reviewer lent me a copy of an article to peer review along with him), this means that you have a general idea of how things work in that field. If someone states something controversial, you'll use an extremely critical eye. If something is really controversial, then it might have trouble getting published in a 'high-quality' journal. But that doesn't stop people, because one you publish something, people will inevitably check your result. If it turns out to be true, your status as a research skyrockets. You'll be able to get later articles in high-quality journals
Is there enough scientific evidence to disprove the ordinary person's idea of free will?
The
ordinary person's? Yes. It's obvious that we
feel like we have free will. But it's equally clear that we don't know
when we've made a decision, and it
feels like we've made a decision much later than we have. We are also really great at post-justifying, creating an illusionary "I meant to do that" justification for our actions. Finally, it's possible to use the environment to control people's actions to a much greater degree than people have any idea about
