Larry Niven wrote an interesting short story (I forget the name), about aliens who visited Earth, and one of the technological toys they had was the ability to implant knowledge in the brain. The thing was, it was different from the way you normally think about it: usually, in stories like that, the implant gives intellectual knowledge of the subject, but not intuitive knowledge. In this story, it was the exact opposite: if you got the memory for how to fly a spacecraft, you could climb into the cockpit and take off like you'd been doing it for years, without giving it a second thought. But if somebody asked you to explain how to fly it step-by-step, you'd probably be at a loss for words, or would have to mentally walk through the process to figure out what exactly you were doing, and why.
I thought that was a neat idea. If I recall, one character in the story couldn't even remember which skill he had been given, because he was drunk when he got it, and you can't just sit down and write a list of the things you can do today that you couldn't do yesterday. He had to wait until his new skill manifested itself before he could figure it out.
