Why do you lose memories when you teleport and why do you posit that I have a continuous memory from birth to now? — Hanover
You're free to say you were not 'you' before, say, age 4 when clear memories coalesced. — AmadeusD
You're distinguishing your example from mine — Hanover
But if I go from Point A to Point B over 50 years and not a single same cell or single same memory exists from age 1 to age 50, then don't I have the same identity problem as you noted in the teleporting? — Hanover
Here is a thought experiment - I do not think it is mine, but I cannot remember whose it is — Clearbury
On the other hand, if the mind stays with the functioning, then the mind stays where it is and the reassembled brain is either just a lump of meat or another mind, but it isn't the original one. — Clearbury
This is a conclusion for a different thought experiment, on my view. — AmadeusD

The brain has all the connections it had before it was removed from your body, so she will have your memories.
And I think that's absurd. It's not the case that Jane forgets her life and remembers yours; it's the case that Jane is dead and you're alive in her body.
I can't be a single person in two disconnected bodies with two disconnected brains, and neither half is somehow privileged such that one is me and the other isn't. So it must be that neither is me. Therefore I'm dead.
You mean my brain is alive in her body. — NOS4A2
But your brain is still alive. If a person is a brain, and the brain is still alive, the person is still alive, no? — NOS4A2
It’s why you cannot imagine yourself being a disembodied brain without some sort of mechanism to keep you alive while you’re outside the body. — NOS4A2
Decapitation is quickly fatal to humans and most animals. Unconsciousness occurs within seconds without circulating oxygenated blood (brain ischemia). Cell death and irreversible brain damage occurs after 3–6 minutes with no oxygen, due to excitotoxicity. Some anecdotes suggest more extended persistence of human consciousness after decapitation, but most doctors consider this unlikely and consider such accounts to be misapprehensions of reflexive twitching rather than deliberate movement, since deprivation of oxygen must cause nearly immediate coma and death ("[Consciousness is] probably lost within 2–3 seconds, due to a rapid fall of intracranial perfusion of blood").
A laboratory study testing for humane methods of euthanasia in awake animals used EEG monitoring to measure the time duration following decapitation for rats to become fully unconscious, unable to perceive distress and pain. It was estimated that this point was reached within 3–4 seconds, correlating closely with results found in other studies on rodents (2.7 seconds, and 3–6 seconds). The same study also suggested that the massive wave which can be recorded by EEG monitoring approximately one minute after decapitation ultimately reflects brain death. Other studies indicate that electrical activity in the brain has been demonstrated to persist for 13 to 14 seconds following decapitation (although it is disputed as to whether such activity implies that pain is perceived), and a 2010 study reported that decapitation of rats generated responses in EEG indices over a period of 10 seconds that have been linked to nociception across a number of different species of animals, including rats
