That's unclear. The sheer bitrate of reading suggests that it might tap into some deep structures -- hacking some parts of the visual and speech systems, if you prefer.

I don't click on HN video links because I find video slow and frustrating way to learn almost anything. Text is so random access -- you can skip over boring bits re-read hard bits, luxuriate in the really wonderful bits...all of which is hard in video. And in fact because the visual channel is so complex, I find reading more multimedia than video -- it's hard to feel cold when watching someone march through the snow, though a well written book can make me shiver with cold, even on a summer day.
