Re: Memory storage and transplant

All of these ideas are fascinating possibilities.  Science fiction authors 
have had fun with them for years, but scientists (I hate to disappoint you) 
are nowhere near being able to do any of these things.  A big part of the 
problem is that we don't know very much about how memories are represented 
in the brain.  Some memories seem to be concentrated in one place.  For 
example, after getting hit on the head, someone might forget the words used 
to name different fruits, but appear to be otherwise unaffected.  Other 
memories seem to be distributed (scattered around) so that injury can 
degrade the memory but not wipe it out.  There seem to be many different 
kinds of memory including iconic memory, the visual-spatial sketchpad, the 
phonological loop, procedural memory, episodic memory and so on.  
Scientists who study these things know they haven't got even the different 
kinds of memory sorted out, much less how information gets in, stays 
intact, and later get retrieved.

Once we understand more about memory, your ideas might become possible.  In 
fact, people have already gotten started on similar ideas.  For example, we 
are now able to attach electrodes to the heads of totally paralyzed people 
which "read minds" just well enough to know whether they want to answer yes 
or no to a question.  Similarly, these machines can allow a person to 
mentally move a pointer on a computer screen and thereby communicate, 
though slowly.  You may want to look up the work of a computer scientist 
named Hans Moravec who has looked into the possibility of downloading 
memory into a computer.
