Again I recommend a literature review. People take this too lightly. I once knew a guy doing his PhD in Electrical Engineering who was working in advanced propulsion, whose doctoral advisors did not require him to do a literature review because they presumed nothing like what they were building had ever been built; and fifteen years later it turned out the device the lab he built was using was the exact same form as an electromechanical device already in use for 80 years. Had the advisors required the standard literature review the experimental work would have saved literally fifteen years wasted effort. (I did the literature review over 3 years so I was the one who discovered this. The devise in the lab was not patentable because it was not novel. Big problem to have after 15 years.)
Always check to see what others have contributed. It makes you better educated and saves reinventing the wheel. You will think very differently about the subject when you know what others have already thought.
So far as I am aware, all PhD studies start with about a year long literature review, and you should keep notes in a form that you can access them easily in the future. Copy and paste sentences and paragraphs from important finds with the standard reference into a single document you can draw from in the future. If you ever decide to share your findings, you will need to convince others, and that will require a paper with references in whatever is today’s standard format. 30 years ago that was APA format. 40 years ago it was Chicago format. I think the current style guide is
MLA. You can learn all you need about it from clicking that link. Don’t be concerned. The point of a standard format for things like footnotes or endnotes is to make using them as easy as possible. It only takes a few seconds to save a reference properly and each one could save you many hours of grief in the future. BTW, the converse is true also. If you fail to write about your work in standard format in what is essentially a “white paper”, no one will take you seriously. Very smart people have this problem all the time. The superb physicist Eric Weinstein has had trouble for years getting other physicists look at his work because he hasn’t yet written a cogent white paper.
I also knew a guy at CIA who was an MD and Uber neurosomething or other. He was doing cutting edge fMRI 15 years ago. All the way back then, he said the fMRI was a foolproof lie detector. If that kind of facility was available 15 years ago when that machine was barely a year old, you can rest assured the literature on it is vast. You’ll have plenty to choose from. The majority concerns treating concussion, which you can neatly set aside.
Innovation is adventure. However, if you want your adventure to ever be useful, you have to be able to communicate it clearly in the specialized language of people in the field—proper jargon. If you create your own jargon, you need to explain it when you introduce it. Mastering jargon is not just a badge of honor. It is a sign of mastery you’ll need.
From what we have all seen in this forum, you are an excellent communicator, so put in the effort. You’ll be glad you did.
Finally, keep in mind what your review tells you is not always what you want. While learning the subject you could find your thoughts are not novel, or that they are just wrong. If that happens you may be set on another path, but if that happens or not; best is you know. You need to know.
