Actually, there’s more than one screen. I’m surrounded by them. Each wall of this room is a screen, and the technicians can subdivide them all so that they display different images. I can see my mind all around me, on all the screens. I’m looking down along the line of my body—in general I hate this position because it gives me an almost endless collection of chins—at the screen beyond my feet, which is presently the least busy of them all. These words are in the middle, between an ECG trace and something that looks like a sonogram.
