Evolution of Sleep Sleep is very ancient. In the electroencephalographic sense we share it with all the primates and almost all the other mammals and birds: it may extend back as far as the reptiles. There is some evidence that the two types of sleep, dreaming and dreamless, depend on the life-style of the animal, and that predators are statistically much more likely to dream than prey, which are in turn much more likely to experience dreamless sleep. In dream sleep, the animal is powerfully immobilized and remarkably unresponsive to external stimuli. Dreamless sleep is much shallower, and we have all witnessed cats or dogs cocking their ears to a sound when apparently fast asleep.

Blind from birth, Wonder has waited his whole life for a chance to see. Recently, Wonder visited Mark Hamayan, a vision specialist. He thought that a new device currently being studied by Humayan might offer him that chance. The device, a retinal prosthesis, is a tiny computer chip implanted inside a patient’s eye. The chip sends images to the brain and allows some sightless people to see shapes and colors. Wonder hoped the retinal prosthesis might work for him. "I’ve always said that if ever there’s possibility of my seeing," said Wonder, "then I would take the challenge." Unfortunately for Wonder, that challenge will have to wait. Humayan explained that the device isn’t ready for people who have been blind since birth. Their brains may not be able to handle signals from a retinal prosthesis because their br A.
