Amnesiac PCs in THS

[Michael Thayne]

Now I'm trying to nail down cannon about how bioroid brains work. The answer has to be "very differently than a normal human brain", because otherwise new bioroids would just be overgrown toddlers. But the exact nature of these coincidences isn't as clear.

• The very first vignette on p. 7 of the main Transhuman Space book indicates that bioroids receive "virtuality training simulations" while still in their biogenesis tanks. The same book on p. 76 says that "A newly formed bioroid brain is designed to awaken in a state highly receptive to learning," but doesn't elaborate on that very much beyond vague mentions that brain implants, virtuality, and slinkies are important parts of bioroid training.
• Deep Beyond on p. 109 has another vignette that describes what those "virtuality training simulations" that happen in the biogenesis tanks are like from the bioroid's point of view.
• Transhuman Space: Bio-Tech 2100 has maybe one of the most detailed descriptions I've read of what's supposed to make bioroid brains special:

  That mostly just left the brain, as artificial brains obviously weren’t needed for transplants – but academics had worked on constructing organic brains from scratch, for purposes such as abortive "biocomputer" projects and as test beds for neural interface systems and other fields of research. Researchers then proved that they could "program" them with "direct neural education" technologies, which worked far better with constructed brains than they ever could with naturally grown organs, because the former had well-documented, regular structures that could be designed from the start to receive these inputs.

  However, the degree of control available to bioroid "programmers", and whether "direct neural education" is any different than "virtuality training", is not totally clear from this paragraph.
• Personnel Files p. 34 has a sample bioroid character named Sally Xan, who was rescued from the Triads by the Martian Commonwealth. A sidebar raises the possibility she got some special modifications after being rescued, unbeknownst to her. It explains, "She was very new back then, and her memories could have been adjusted during her early training." This implies new bioroids can have memories selectively erased, which is not explicit in the other books cited above.
• There's also the already-mentioned article in Pyramid #3/15. It might have lower canonicity than the other sources cited above, and seems to take a more extreme view of what bioroid "programming" can do. On the other hand, if the Personnel Files sidebar is canon, maybe the things described in "Dark Places of the Earth" are too.

I've been looking pretty hard for relevant canon in my THS books, but I might be missing something. Anyone know of anything else I should be paying attention to?
