This post is irony at a base level.
You ultimately have to sift through a lot of books to get past popular books like Godel, Escher, Bach and on to something like Philosophical Foundations of Neuroscience.

They don't need to do it in the same way humans do; they don't do it in the same way humans do. In the absence of language, they have no way of expressing the depths of cogitation in the same way humans can.
In regards to your last question, I have found PMS Hacker a particularly compelling author in this area. He is a very good analytical philosopher. His works are peer-reviewed, and extensively researched and amply sourced. He's an established professional philosopher. He has also written extensively with M.R. Bennet, an established neuroscientist with many papers, a good book of theirs is: The Philosophical Foundations of Neuroscience (http://ca.wiley.com/WileyCDA/WileyTitle/productCd-140510838X...)
I'm not a professional scientist, I don't have access to papers. I have access to books.

They may add clarity and precision where I have made a gloss.
PMS Hacker and most Wittgensteinians come to this conclusion; it is largely the reason why they find any value in Freudian/Gestalt psychology: for the fact that these brands of psychology avoid, as much as they can, reductionist, and this is for the fact that their theories depend on building metanarratives _on top of_ "folk psychology" rather than attempting to undercut folk psychology with some more primitive theory. The whole debate turns on which theories have better "explanatory power" while preserving our intuitive notions of the brain. Wittgenstein criticized Freudians for mistaking "decision" for "discovery"; and this is exactly what "Crypto-Cartesians" do except what is discover is not a psychological law à la Freud, but rather a neurological law. Now, of course, in their own worlds, these laws make sense; there are law like relations between, say, joy and pain; their are laws between synaptic path/subsystems and the behavior of neurons. However, talking about those laws does not give us direct insight into the _organism for which those laws have constituted_.
It should be clear that if free will is not possible, then we must wonder why we decided to look inside the brain, rather than the foot, to discover why it is not possible. The problem, like with the Freudians, is that identity claims like You === Your Brain are a matter of decision, not discovery. We might decide and agree such identity claims, but not without doing severe damage to the common language which we use to identify correlations and criteria which support as evidence those claims.
What these scientists are trying to do is make their position _compelling_; that is the fundamental problem here since engaging in such "justificatory" activity is a feature of science itself (i.e., peer review). This feature of the structure of scientific practice, by and large, makes it "absurd, on its face." These scientists attempt to pass off as discovery what can, by the nature of science itself, only be suggestion, persuasion, justification.
Please also review "[The Philosophical Foundations of Neuroscience](http://www.goodreads.com/book/show/369939.Philosophical_Foun...)."
The former is a more consistent notion than the latter. More consistent with the evidence, etc. cited. Thinking 'in' language implies passivity and representation, thinking into language implies evolutionarily novel linguistic production, autonomy of mind, etc.
Please review The Philosophical Foundations of Neuroscience.
Edit: I even have another half a dozen of them in my cart, but I can't keep buying books...
