"As a brain donor, your brain will be used for research purposes only—it will not be given to another person." How many people had to ask/worry about that for them to write it? Isaac Arthur's YouTube video on identity[1] includes a comment "if someone transplanted Bob's brain into Joe's body, we would not think of it as Joe-with-Bob's-brain, but rather Bob-with-Joe's-body". In that sense it might be impossible to give my brain to another person, it would be more like giving me their body; but what if it was only a bit of my brain? If my motor cortex could be transplanted into a stroke victim or a Parkinson's patient, or whatever; writing that down doesn't sound objectionably or identity-breaking.
