When the Resolving Imager had just been developed, scanning such a huge quantity of cross sections generated powerful radiation that was fatal to any life being scanned, but successive improvements had brought the radiation below the danger line, and a large number of tests had demonstrated that so long as filming was kept below a set length of time, the Resolving Imager would not cause any damage to the brain.

“He seems to have caught hydrophobia,” the medical director said, as they hurried toward the medical center.

Hines and Keiko Yamasuki stopped in their tracks in surprise. Hines stared at the medical director: “Hydrophobia? Did he somehow get rabies?”

The medical director raised a hand and tried to sort out his thoughts: “Oh, I’m sorry. That wasn’t accurate. He doesn’t have any physical problems, and his brain and other organs have not been damaged at all. It’s just that he’s afraid of the water, like someone with rabies. He refuses to drink, and he won’t even eat moist food. It’s an entirely psychological effect. He just believes that water is toxic.”

“Persecutory delusion?” Keiko Yamasuki asked.

The medical director waved a hand. “No, no. He doesn’t think that anyone put poison in the water. He just believes the water itself is toxic.”

Again, Hines and his wife stopped still, and the medical director shook his head helplessly. “But psychologically, he’s completely normal in every other way.… I can’t explain it. You’ve got to see it for yourselves.”

Subject 104 was a volunteer college student who had come to earn some pocket money. Before they entered the patient’s room, the director told Hines and his wife, “He hasn’t had a drink in two days. If this continues, he’ll become severely dehydrated and we’ll have to hydrate him by force.” Standing at the door he pointed to a microwave oven, and said, “You see that? He wants bread and other food baked completely dry before he’ll eat it.”

Hines and his wife entered the patient’s room. Subject 104 looked at them with fear in his eyes. His lips were cracked and his hair disheveled, but otherwise he looked entirely normal. He tugged at Hines’s sleeve and said in a hoarse voice, “Dr. Hines, they want to kill me. I don’t know why.” Then he pointed a finger at a glass of water sitting on the cabinet next to the head of the bed. “They want me to drink water.”

Hines looked at the glass of clear water, certain that the subject did not have rabies, because true hydrophobia would cause spasms of terror at the mere sight of it. The sound of running water would induce madness, and there might even be an intense fear response if others simply talked about it.
