due to my own tbi, I'm very interested in this memory discussion.  All I had
heard of until now is short-term and long-term memory.  My most apparent
difficulties appear in accessing what I know.  What I know residing in
long-term memory, and the access difficulty resulting short-term memory
troubles.  I've compared my brain to a PC, saying my hard drive is ok, but
my RAM is lacking.  I've noted numerous references - thanks all!  Can anyone
share advice or help me better understand the physical explanations to my

If anyone's interested in more details say so, or check out my ramblings on
