References and easter eggs you found

[Omnitool]

At certain points in the game (in the computer at Theta where the legacy scans are stored, and there is another reference at some point) a scan is refered to as a "Nakajima neurograph". Googling the term came up with a book on brain imaging, and one of the quoted scientific publications on which the book is based was published by a researcher named Nakajima H.
The article and book is basically about research in using MRI brain scans to find better treatments for neurological diseases, similar to what Dr. Munshi was trying to accomplish through his research.
