Are they still “imprinted”?

The brain is a lot more like RAM in a computer than it is, say a Hard Drive. Meaning if the power is shut off, the information stored there is lost fairly quickly, hence why it’s important to try and revive non-responsive people as quickly as possible, and why people who are medically dead and then revived often have some symptoms of amnesia.

In more depth, we don’t really understand yet how the brain’s memory really functions. Further complicating things is that no two brains are wired quite the same so even if you expose two individuals to the same experiences their entire lives, small differences in genetics mean their brains will work very differently. This means that even if we manage to somehow preserve a brain a manner in which the neuron pathways and electrical transmissions are never lost, we have no real way to access that “information”, nor is there a way to tie that brain into the nervous system of a different body.
