You should wait. I don't work in neuroscience per se, but I am a biologist and I have some friends who are (or have been) neuroscientists. The long and short of it is that the technology and underlying theoretical framework for understanding cognition just aren't in place yet. There's plenty of interesting research being done but the field hasn't had its "quantum leap" yet, as it were. (Examples of this from other fields are Newton's Principia, discovery of DNA structure/Central Dogma of Molecular Biology, etc.).

EDIT: I realized this sounds very discouraging to laymen trying to learn more about science. This was not my intention! By all means, go forth and learn! :) My point was simply that press releases / news often make it seem like science advances at a breakneck pace all the time, whereas reality is that it's fits and starts and often we haven't the slightest clue what we're doing.
