In my opinion, its definitely not just in the brain. If I try to play early in the morning, even after I've had my caffeine, the fingers of both hands just don't work all that well. By the afternoon the brain may be sluggish and in need of a nap, but the fingers are warm and much more capable. Of course you need both the mental and finger facility. But clearly warmed up fingers is really a physical thing.
