Predatory Game (GhostWalkers, #6)(103)
Saber sighed. She’d said “in theory.” He had chosen to ignore that part. To trigger the program she needed to send a steady stream of electrical signal to the right place at the right time. The body’s own biological regrowth program for that particular area would take over and do the rest. It sure beat trying to micromanage the regrowth process herself—that is, if Whitney was correct in his findings. She could just watch it kick in after she jump-started it.
“Come on, Saber, let’s do this.”
She scowled at him. “You know this isn’t quite as easy as you want it to be. For one thing, aside from having never done it, I have to learn all kinds of little details. I have to be careful when healing wounds to apply the electrical current in the right direction. If I blow it, the wound would open up instead of close. This is going to take a little time until I figure out what I’m doing.”
He rubbed his hand up and down her arm. “I’m sorry. I know it’s going to work, Saber. If you do this, I’ll be able to walk again.”
“Well, don’t talk to me anymore. Let me visualize this.” Because she was scared now. She’d killed over and over again with the touch of her hand. Now she was going to do something good for a change—if she didn’t blow it and do further damage. And she was going to have to follow Dr. Whitney’s instructions verbatim. He had written that report for her to read, knowing she would read it and retain every word. He had described in great detail what needed to be done and how to do it. First she had to shrivel up the damaged nerve segment, using a targeted burst of electrical current. Then she needed to grow a new nerve segment to replace it.
Growth of new nerves—neurogenesis—took a special application of her skill. Like an artist, she would “direct” the electrical field from one point to another—across the gap where the damaged nerve segment used to be—“painting” where she wanted the new nerve pathway to appear. This would set up an electrical field across the space she was visualizing, and nerve cells would start growing in the direction she had “commanded.”
She started tentatively, and found that for growing neural pathways, a pulsed electrical current worked much better than a steady one. With persistence, she could generate an entire nerve segment. It was an amazing feeling. The nerve cells felt like plants sprouting in her mind; she visualized them that way. Some would push out tentative tendrils that would grow around neighboring cells. Others would retract if they touched other cells.
Once she grew some new nerve cells, she “fired” them repeatedly—just as if Jess were using those nerve cells over and over again, to break them in and to trigger growth of even newer neurons hanging off of them. If she generated more current, it resulted in faster growth of new nerve cells…but she also had to be careful to not overdo it and “fry” the new nerve segment she was creating.
It was an exhausting business, but she grew more confident as she realized the useless tissue and cells were being replaced by healthy muscle and nerves. She concentrated on the most damaged areas, around the bionics where the electrical signals had been severed, and stimulated the growth in those precise muscles and nerves needed to drive the bionics.
Growth of new muscle tissue required a little something, she discovered; it was actually easier than regenerating nerves, but required great precision for long periods of time. If she applied just the right amount of electrical current at just the right place on the edge of the healthy muscle tissue, she would trigger a biological program already built into the body, a program for regrowing new muscle tissue to replace old damaged tissue. She just had to keep the level of current steady to keep the body’s program running and sit back and “feel” it do the rest of the work. It sure beat having to micromanage all the zillions of muscle cells. She was so exhausted, she wouldn’t have been able to continue.
She pulled her hand away from Jess’s legs, aware of the time passage only because she was swaying with weariness. The room had been so silent while she worked, and when she glanced at the monitor, Ryland was watching with his wife.
Jess lay very still for a long while, so long that Saber’s heart began to accelerate. She touched his shoulder. “Are you all right?”
He glanced at her and then at the monitor. “Yes. I feel fine. Just not any different. While you were working my legs were warm, and I actually felt a couple of zaps, but now I’m not feeling much of anything.” He sat up slowly.
Lily smiled at him. “If you don’t see any improvement within twenty-four hours, you should try again. This is amazing, Saber.”
“Only if it worked,” Saber said.
“I’d like to stay and talk, this is really exciting, but I think I’m going to be having a baby here pretty soon.”
“You mean in a few weeks,” Jess corrected.
“I mean in a few hours. If you need anything else, call Eric. I’ll be out of touch for a while.”
Ryland stuck his head around Lily, a grin splitting his face from ear to ear. “We’re having a baby, Jess!”
Jess laughed. “I can see that. Good luck to both of you. Let us know everyone’s all right the minute it comes into the world.”
“I will,” Ryland promised.
Lily blew a kiss to Jess. “Be happy, you two.”
The monitor went dark and Saber flicked it off. She turned to Jess. “I can’t believe she sat there in labor the entire time. I would have been freaking out.”
