Besides, even if possible, surely it would need sensors attaching to the head to detect whatever are the thought "signals"?

(Not that most of us would necessarily be able to read the paper even if sufficiently knowledgable. The big publishers like Elsevier have sewn up the scientific-papers trade very tightly and made access extremely expensive. Even many of the scientist authors now complain they are often unable to re-read their own past individual or contributed papers, unless they had ensured from the start, retaining copies privately!)
