Neurons for me as well. I play the piano for my own amusement and the best music I play is the music that comes from my memory. There's no struggle to read the music, and no time lag between the brain and the fingers. Memorized music starts in the neurons, but is intimately connected with some sort of physical memory in my hands as well. It just flows out across the keyboard. If I have to write the music down, I can't. I can only play it out. It amazes me the way the brain works, providing me with endless hours of amusement.

I work on the computer the same way. If someone asks me to tell them how I do something on the computer I have to show them, because the words aren't always there either. Straight from brain to keyboard, by-passing the verbal translation center. (Puts me at a slight disadvantage in answering questions here in the monastery.)
