“You could be more specific,” he said thoughtfully. It was a tempting idea. Instead of prying answers out of untrained observers, Joanna would know what to look for, how to describe it. She would be able to tell him whether what she saw was a superimposed vision or a hallucination and what subjects meant when they insisted it wasn’t a dream.
More than that, she’d recognize the sensations for what they were. She’d know that certain effects were due to temporal-lobe stimulation or endorphins, and she could provide valuable information about the processes causing the sensations. She would know—
And that was just the problem. “It won’t work,” he said. “You said yourself a subject shouldn’t have preconceptions about what he was going to experience. You’ve interviewed over a hundred people. You’ve read all the books. How do you know your experience wouldn’t be totally shaped by them?”
“It’s a possibility,” she said. “On the other hand, I’d have the advantage of being on guard. If I found myself in a dark enclosed space I wouldn’t automatically assume it was a tunnel, and if I saw a figure radiating light, I definitely wouldn’t assume it was an angel. I’d look at it—really look at it—and then tell you what I saw, without waiting for you to ask.”
Richard held his hands up in surrender. “You’ve convinced me. If one of us were going under, you’d be the best one,” he said, “but neither of us is going under. We still have four volunteers left, and what we should be doing is concentrating on how to make them more effective.”
“Or present,” Joanna said.
“Exactly. I want you to call Mrs. Haighton and get her in here for a session.”
“I haven’t even interviewed her yet,” Joanna said doubtfully.
“Do it over the phone if you have to. Tell her how much we need her. In the meantime, I’ll work on Mrs. Troudtheim.”
“What about Mr. Sage?”
“We’ll get a crowbar,” he said and grinned at her.
Joanna left to call Mrs. Haighton, and he went back to comparing Mrs. Troudtheim’s data with the scans of the other subjects just prior to the NDE-state, looking for differences, but they were identical. Joanna had said some patients didn’t have NDEs. He wondered which ones.
He went down to her office to ask her. She was just coming out, wearing her coat. “Where are you going?” he asked her.
“To the Wilshire Country Club,” she said in an affected, aristocratic voice. “I couldn’t get Mrs. Haighton on the phone, but her housekeeper told me she was setting up for the Junior Guild Spring Fling, whatever that is, so I’m going to see if I can catch her there.”
“Spring Fling?” Richard said. “It’s the middle of winter.”
“I know,” Joanna said, pulling on her gloves. “Vielle called. She says it’s snowing outside. I’ll be back in time for Mrs. Troudtheim’s session.” She started walking toward the elevator.
“Wait a minute,” Richard said. “I need to ask you a question about patients who have NDEs versus patients who don’t. Is there a pattern to it?”
“Not a reliable one,” she said, pressing the “down” button. “NDEs mostly occur in certain types of death—heart attacks, drownings, car accidents, childbirth complications—but that may be just because patients with those sorts of traumas are more likely to be revived than patients with, say, a stroke or traumatic internal injuries.” The elevator opened.
“And the patients who don’t have NDEs tend to have coded from other causes?”
She nodded. “But of course we don’t know if they didn’t have an NDE, or if they had one but simply didn’t remember it,” she said, and got in the elevator. “Remember, before techniques for recording REM sleep, it was thought that certain people didn’t dream.”
The door shut. Heart attacks, drownings, car accidents, Richard thought, staring blindly at the door. All traumatic events, with a high level of epinephrine. And cortisol.
He went back to the lab and called up Mrs. Troudtheim’s analysis and looked at the cortisol level. It was high, but no higher than Amelia Tanaka’s during her fourth session, the one in which she had been under nearly five minutes. The epinephrine was slightly lower, but no lower than Mr. Sage’s, and he’d had no trouble achieving an NDE-state, even if he was maddeningly vague about describing it.
Maybe the problem was a lack of receptor sites. He brought up Mrs. Troudtheim’s scans and started through them, focusing on the hippocampus. Yellow activity along the hippocampus edges, where there were large numbers of cortisol receptor sites. He went forward through the frames and then backward, mapping the areas of activity. The anterior hippocampus went from yellow to orange and then red. He clicked back another single frame, looking at the edges and then at the epinephrine receptor sites in the—
He stared at the screen, clicked on “stop,” made it go back three frames, and then forward again to the same frame, and stared at the screen again. He clicked on “side-by-side,” and called up the standard and then Amelia Tanaka’s scan.
There was no mistaking it. “Well, at least I know it’s not insufficient epinephrine,” he muttered. Because what he was looking at was unmistakably the brain in an NDE-state.
He did a superimpose with Mr. O’Reirdon’s scan to make sure, but it was already obvious. Mrs. Troudtheim had had an NDE.
The pattern only lasted a single frame, but it changed the whole nature of the problem. He had been focused on what was preventing Mrs. Troudtheim from achieving the NDE-state, but she had had one. The problem was that she hadn’t been able to sustain it. Why not? Why had she immediately bounced out of it and into a waking state? And had this happened before?
He began mapping the NDE frame, looking for anomalies that might explain the NDE’s nonsustainability. Nothing. It showed the same red-level activity in the right anterior temporal lobe, the amygdala, and the hippocampus, the same random scattering of orange- and yellow-level activity in the frontal cortex.
Joanna came back, her hair windblown and her cheeks pink from the cold and handed him an orange-and-yellow-green crocheted thing in a small clay pot. “From the Spring Fling,” she said.
“What is it?” he said, turning the pot around.
“A marigold. A crocheted marigold. I thought of you as soon as I saw it. I know how fond you are of orange and vile green.”
“Did you see Mrs. Haighton?”
“Yes, and interviewed her, and she’s fine, no secret supernatural beliefs, and she’s scheduled to come in Thursday afternoon. I know, that’s Mr. Sage’s slot, but between the Philharmonic Guild and the charity fashion show, it was the only time she was available, so I decided it was worth moving him. I’m going to call him now.”
“Wait a minute,” Richard said. “I want to show you something.” He showed her the side-by-side of the standard and Mrs. Troudtheim’s NDE frame.
“She had an NDE?” Joanna said. “Do you think she’s lying to us about not remembering it?”
That idea hadn’t occurred to him. “No,” he said. “It only lasted a tenth of a second, if that. I doubt if she’s even aware it happened. If she is, it’s probably only as a flicker of light. Or darkness. But it changes the nature of the problem. She’s achieving the NDE-state, but something’s short-circuiting it. I’ve got to find out what that something is.”
He worked on doing just that the rest of the day and the next morning. He mapped the frames before and after the NDE, and then went back over the scans of Mrs. Troudtheim’s other sessions. He found an identical pattern in her second set of scans. There were none in the other sessions, but the RIPT images were a hundredth of a second apart. If the NDE-state was shorter than that, it would only show up part of the time, and the frames immediately succeeding the two NDE frames were identical to frames in the others.
