I'm trying to get some of my facts straight regarding how memory travel and modification work. I know for sure I missed out on quite a few things and I'm hoping some of you TtM smarties will help me out
I've organized my knowledge into things I know for sure, things I surmised, things I'm not too sure about, and theories I have.
.Things I know for sure (since they are either explicitly stated or presented)
Memory hopping requires the use of "mementos".
Mementos are protected by a barrier which requires five memory-links to break.
Agents/Doctors have the capacity to pause, reset, interact with, and move anything and everything within the memory they are currently viewing.
New memories do not overwrite old ones. Conflicting memories would then cause a patient to go mad or harm then mentally (Contribution thanks to Dragon Mage).
The machine comes with a "wiki of data" to help reconstruct new memories (Contribution thanks to Dragon Mage).
There is a finalization process. Doctors can perform a "safe reset" so long as they don't finalize the rewrite (Contribution thanks to Thunderbird)Things I've surmised (through game-play generally)
Upon entering the client's memories, one will arrive in that client's most recent memory.
The initial memento provided by the client in his or her most recent memory will not require five memory-links.
The "preparation" of a memento becomes more and more complicated in conjunction with the number of memory hops a doctor (or two) has managed to achieve prior.
When interacting with other people in a client's memory, the behavior will conform to how the client would think they would act, rather than how they would actually act in reality.Things I'm not too sure about
When doctors modify a patient's memory, any memories that take place afterwards will change to become consistent with the modified memory. If a change is inconsequential or does very little to affect one's desires, then no change will occur in future memories.
With Eva "moving" River from Johnny's memories to his newly reconfigured memories, I get the sense that the doctors are able to manipulate artificial memories with more ease than they can with the client's original memories.
I'm not too sure if traveling to a patient's childhood memories are the only method in which a doctor can manipulate their client's memories. Though I don't have any proof to infer to, it seems reasonable to think one can begin modifying a client's memory at any stage in their development.
Doctors can reset a modified memory back to its original form without any harm to the client.
(Modification thanks to Thunderbird)My Crazy Theories
The barrier that protects mementos is the mind's natural defense to what is otherwise a very intrusive operation.
The first memento doesn't have a barrier to break because the client, albeit just a memory program, is willfully providing the memento him or herself.
That's pretty much all I know, or think I know. If something needs to be removed from the list, please tell me. If something needs to be added to the list, please tell me. If something needs to be moved from one part of this list to another part of this list, please tell me
