Here is a database of open-access journals, I've done the search for neuroscience for you
Be wary though, this database doesn't list the impact factors (i.e. credibility) of these journals. You should check them against something like the Thompson Reuters database first.
Many articles become free after a while due to US law. So if you search eg. "deep brain stimulation parkinson's" it will come up with 2675 articles. On the right column under "Filter your results", there's the option to restrict the search results to the 450 articles which are free.
Impact factors are not credibility ratings.
Yes, that is why I indicated that they are different things. However impact factors are an important thing to consider when looking at the credibility of a journal.
I don't think so.
I don't think so, either. Impact factor is obscured by novelty and significance, which has nothing to do with credibility.
Just because research wont save lives or make a pharmaceutical company rich doesn't mean it lacks credibility.
Conversely, a parmaceutical company can very easily get into a high-impact journal with some very selective reporting as long as a disclosure is included in a little paragraph at the end.
I'm not saying it is a perfect system, there are many effects that manipulate the numbers but considering the OP is starting from a laymans perspective I think it is an ok thing to look at to get a rough (but not absolute) idea.
Yeah, I think that's ok just to start with those reservations in mind.
