  20. All kinds of tired

    Donkeys sleep about three out of each 24 hours. Certain reef fish spend the night moving their fins as if swimming in their sleep. Some biologists argue that all animals sleep in some form or another. But identifying sleep can get complicated. Insects have brain architecture so different from humans’, for example, that electrophysiological recordings […]

  21. The Why of Sleep

    In a lab at MIT, a small black mouse named Buddy sleeps alone inside a box. A cone resembling a satellite dish sits atop his head. But the dish doesn’t receive signals from outer space. Instead it sends transmissions from deep inside Buddy’s brain to a bank of computers across the room. SILENT ACTIVITY In […]
