Interface. Part 13

Zeldo did not laugh. Dr. Radhakrishnan was beginning to get that tingly feeling in his hands.

He stuck his head out of the office and looked down the hallway. Mr. Scatflinger was lying on the gurney, quiescent, his head freshly shaved, blue lines drawn on his scalp like the rhumb lines of an ancient navigator.

"Can you or can you not reprogram this thing remotely, after implantation?"

"We can modify the software. That's how we're programming it as we speak. It's sitting in the culture tank and we're talking to it over the radio."

"It's finished."

"No.""Put the culture tank into the truck and get it over here now. That is an order."

The chip consisted of a silicon part - the part that Zeldo was responsible for - surrounded by an inert teflon sh.e.l.l, connected on either end to brain cells that had been grown in a tank in Seattle. The only way to keep those brain cells alive was to supply them with oxygen and nutrients. The biochip sat in a tank full of a carefully pH-balanced, temperature-regulated, oxygenated chemical solution that Zeldo and the other Americans referred to as "chicken soup." The soup gave the brain cells everything they needed to stay alive, except for intellectual stimulation. The chip was only a couple of centimeters long in its entirety and so the tank itself wasn't that large, just a few liters in size. But it was attached to a variety of machines to keep it properly balanced and regulated, so the apparatus as a whole ended up being roughly the size of a vending machine. It rolled around on oversized rubber wheels, and it had enough built-in backup battery power so that it could be unplugged from the wall for up to half an hour.

All of this portability was needed, for the time being, because of the far-flung nature of this enterprise.

The chips had first been incarnated in Seattle, placed into this tank, and then rolled on board a specially chartered G.o.dS jet, where the support systems had drawn power from the airplane's generators. From the Indira Gandhi International Airport, the whole mess had been transported to the Barracks for debugging.

Now it had to be s.h.i.+pped down the road to AIIMS for the actual surgical procedure. Each time it was trundled from one place to another it had to survive on battery power for a few minutes.

Zeldo and his cohorts referred to the apparatus as the Cabinet of Dr. Caligari. They hauled it around in the back of a truck. The truck poked its way slowly down the Delhi Ring Road, pulled off into the parking lots of AIIMS, and backed up to a loading dock.

The back door flew open and there were Zeldo and his hackers, surrounding the Cabinet of Dr. Caligari, all blinking lights and bubbling tubes.

There was an interval of half an hour or so, during which the patients were prepared for surgery, the operating room people got scrubbed and gloved, and Zeldo and his crew got the Cabinet of Dr. Caligari transferred across the hospital to the operating theater, leapfrogging from one power outlet to the next, down hallways and up elevators. Then Dr. Radhakrishnan just had to perform a couple of operations.

It was strange, and possibly ludicrous, to be doing both Mr. Easyrider and Mr. Scatflinger at the same time. Each operation was a major event in itself. But there were many strange and ludicrous things about the way the Radhakrishnan Inst.i.tute was currently functioning. As they went over the plans for this day, they had all shared a creepy, unspoken feeling that they were extending themselves years beyond where they really ought to be, and that many things might go wrong.

The operations were conceptually simple. Incisions were made along the lines that had been drawn on the patients' shave heads. Flaps of scalp were peeled back and the bleeding was cauterized or clamped off.

When the actual skull was exposed, Dr. Radhakrishnan cut through it with a bone saw.

A polygon of skull, a trap door of sorts, was cut into the side of the head and saved for later use. Still, the brain itself was not exposed; they looked through the hole at a tough inner membrane, the brain's final layer of protection. When this was flapped out of the way, they were looking at actual brain matter.

"It was a debacle. I am personally ashamed. I will never do anything like that again. The level of incompetence makes me physically ill. I may shoot myself," Dr. Radhakrishnan was saying.

"Have a drink," Mr. Salvador said. This was easy to arrange because they were sitting in the bar of the Imperial.

"When I am tense I bite my lip. Today I think I have swallowed half of my own blood supply."

"Think of it as opening day for a new business venture," Mr. Salvador said. "It's always a debacle."

"Even debacle does not do justice to this day," Dr. Radhakrishnan said. "It was an apocalypse."

Mr. Salvador shrugged. "That's why we make mistakes, so we can learn from them."

"One gets very impatient, doing research for years and years. The pace is so gradual. After a while you say, "I wish I could just get on with it and put one of these things into a human brain and see what happens.

But this business today reminds me of why we take years and years to get ready for these things."

"The patients are both alive. All's well that ends well."A waiter came by and gave Dr. Radhakrishnan another drink. Mr. Salvador tossed some rupees on to the table. "Why don't you take that with you?" he said. "I have something to show you."

"What?"

"Let's go for a spin."

The former site of the Ashok Theatre had been surrounded by a barricade twenty feet high. In places it consisted of chain-link fence with tarps stretched across it. In places it was pieced together with sc.r.a.ps of wood. In and of itself the fence was a considerable investments; the materials that went into it could have housed thousands. Things did not become much clearer after Mr. Salvador and Dr. Radhakrishnan had gotten past the guard at the gate. Most of the site was filled with a scaffolding. It was just a dense three- dimensional web of steel, with some parts of it additionally sh.o.r.ed up with wooden beams. So far most of the work was being done in iron; the scaffolding was intertangled with another web of reinforcing rods.

The density of activity was incredible. The site seemed to contain several workers per square yard, all doing something as fast as they could. Several cranes were active, moving giant prefabricated constructs of reinforcing rod into place.

"All reinforced concrete. So it looks like h.e.l.l until we pour," Mr. Salvador said.

Dr. Radhakrishnan would have gotten lost in a second, but Mr. Salvador knew his way through the tangle. He led him fearlessly into a pa.s.sage that cut through the heart of it, straight in toward the center, brus.h.i.+ng past workers the entire way. He noticed along the way that he was now walking on planks.

Looking down between gaps, he could see straight down one or two stories. The place was extraordinarily well lit with thousands of electric lights strung on long yellow cords. Hundreds more workers were down below them, bending more steel rods into place. Large amounts of concrete had already been poured down there.

As they approached the middle, Dr. Radhakrishnan could see glimpses of more concrete through gaps in the scaffolding. It was a sort of squat concrete obelisk, rectangular in cross-section, rising straight up out of the foundation below them, up to a height of three stories above their heads. It was large enough, perhaps, to put a volleyball court on each level. The walls had a few rectangular openings on each level where, presumably, this part of the building would later be connected to adjacent rooms or hallways.

Thousands of reinforcing bars sprouted from the walls at the levels of the floors-to-be and along the locations of future walls, giving the whole tower a bristly, hairy appearance. The bare concrete walls, still so new and clean they were almost white, had already been partly obscured by conduits, plumbing, and ductwork that grew up and snaked around the structure like tropical vines climbing a tree. Craning his neck to look up towards the top, Dr. Radhakrishnan could see the louvered enclosures of large pieces of machinery mounted on the roof, probably air conditioners and electrical generators.

The obelisk was connected to the surrounding scaffold work by a couple of catwalks, giving it the appearance of a keep in the center of a medieval castle. When they walked across the bridges into the building, they pa.s.sed through some kind of a cultural divide. Everyone working inside here was Korean, j.a.panese, or American and they were speaking English to each other with varying degrees of proficiency. Some of them were wearing smart, clean coveralls, and some of them were wearing ties. Two or three big Calyx computer systems were already up and running, nice ones with huge color screens, and engineers were using them to zoom in on various subsystems.

"This, of course, is the essential core of the operation," Mr. Salvador said. "The only part that you will really need in order to continue your research. It will be ready to use in a week. As long as you don't mind walking through an active construction site in order to reach it, that is."

"Not at all," Dr. Radhakrishnan said.

15.

MERELY SCOOPING OUT A HOLE IN A MAN'S BRAIN AND DROPPING IN a biochip was not enough. It was like a.s.saulting a supercomputer with a Skilsaw and then throwing in a handful of loose silicon chips.

The biochip had to be connected into the brain tissue in billions or trillions of different ways. All of the connections were microscopic and could not be made by the hand of any surgeon. They had to grow.

Brain cells didn't grow. But the connections between them did. The network of linkages was constantly s.h.i.+fting and reconnecting itself in a process that was usually described as "learning." Dr. Radhakrishnan did not really care for this terminology because it contained a value judgement. It implied that every time new synapses were formed inside a person's mind it was because they were memorizing Shakespeare or being taught how to integrate transcendental functions. Of course, in reality most of the internal rewiring that went on in people's brains took place in response to watching game shows on television, being beaten up by family members, figuring out the cheapest place to buy cigarettes, and being conditioned not to mix plaids with stripes.

As soon as it had seemed like it was a safe bet that Mr. Easyrider and Mr. Scatflinger were going to live for while, they were transferred back to the Barracks in a specially equipped ambulance. They were laid side by side in a separate room that had been built onto one end of Building 2. They were connected up to numerous machines, wired into a support system. Each of them had a red polygon on his head, a U-shaped welt, hairy with black sutures, marking the boundary of the flap that had been peeled back during surgery.

In the center of the area outlined by the surgical scar, a bundle of lines was plugged into the patient's head. It pa.s.sed through the middle of the flake of skull that had been neatly sawed out by Dr.

Radhakrishnan's bone saw. While Dr. Radhakrishnan had occupied himself with implanting the biochip, a lesser surgeon - more of a technician, really - had drilled a few holes through the disembodied chunk of skull and implanted a plastic connector. The connector was about the size of a dime and was really a cl.u.s.ter of smaller connections: half a dozen tiny tubes for pa.s.sing fluids in and out, and a miniature, fifty-pin electrical plug, a nearly microscopic version of the port on the back of a computer. Since most communication between the biochip and the outside world was supposed to happen over the radio, only a few of these fifty pins were hooked up to the biochip itself. Most of them were hooked up to sensors that monitored the patient's condition and to the electrostimulus system that was supposed to encourage the growth of new connections between brain and biochip.

When the operation was finished, this connector peeked through the skin, somewhat in the fas.h.i.+on of a wall socket. The researchers could then interface with the patient by sticking a matching plug into the socket; when it was stuck in properly, all of the fluid and electrical connections were made in an instant. So many tubes and wires were crammed together in this bottleneck that they seemed to explode from the side of the patient's head. Some of the connections ran directly to various pieces of bedside machinery that monitored pressure inside the skull, delivered drugs, or helped to oxygenate the brain tissue in the biochip.

Others were taped to the head of the bed, from which they ran over to the nearest wall, pa.s.sed through a hole, and ran through a conduit that connected the two buildings.

The people in Building 1 saw Mr. Easyrider and Mr. Scatflinger as media ent.i.ties, nothing more. No odors, no fluids, just images on TV monitors, tracings on oscilloscopes, graphics on their Calyx workstations, and the occasional disembodied sound effect coming out of a speaker. This, Dr. Radhakrishnan reflected, made it a lot easier to deal with them objectively.

There was not much to do for the first few days. The brain cells in the biochip had not yet had time to connect themselves up to the patients' brain, so the chip was neurologically inert, just a dead piece of shrapnel embedded in the head. Then, one morning at about three o'clock, computer screens all over Building 1 suddenly came alive as a neuron in Mr. Scatflinger's brain hooked up with a neuron on the fringe of the biochip.

As soon as Dr. Radhakrishnan got there, they popped the corks on a few bottles of champagne and thenstood under the monitor for a while, watching the data stream by. Zeldo did some typing on his workstation and brought up a new window on the screen, this one showing a running graph of the brain activity.

"Someone go s.h.i.+ne a light in his eyes," Dr. Radhakrishnan said.

"Yes, Doctor!" said one of his Indian grad students. He ran out of the building, pulling a penlight from his pocket. A few moments later the grad student was visible on the closed-circuit monitor that had been showing live coverage of Mr. Scatflinger from Building 2. All eyes flicked back and forth between the closed-circuit set and the computer monitor as the grad student leaned over the sleeping Mr. Scatflinger, peeled back one of his eyelids with his thumb, and shone the penlight into it.

The graph jumped. The crowd went wild.

"Well done, Doctor," someone was saying. It was Mr. Salvador, shaking his hand, offering a cigar.

"Remarkable success, especially under the circ.u.mstances." Around nine A.M., a burst of activity showed up on Mr. Easyrider's heretofore quiescent monitor. But even in the corner of his eye, Dr. Radhakrishnan could see that something was wrong. The signals coming in from the biochip showed no clear pattern in terms of intensity or duration.

"Glitches," Dr. Radhakrishnan said.

"But a whole h.e.l.l of a lot of glitches," Zeldo said.

"Glicherama," said one of the other Americans. Dr. Radhakrishnan bit his lip, knowing that for the rest of his career, this phenomenon, whenever it occurred, would be referred to as Glicherama.

Sudden movement caught his eye. He looked over at the closed-circuit monitor for Mr. Easyrider and saw, instead of the patient, the backsides of several nurses who were standing around him, working feverishly.

By the time Dr. Radhakrishnan made it over to Building 2, Mr. Easyrider was dead. His heart had stopped beating. They wheeled out the defib cart and shocked him a couple of times, trying to get a stable rhythm back, but in the end they could get nothing but bad rhythms on the scope, and finally no rhythm at all.

When they were sure he was dead, when they had closed his eyes, rolled away the cart, and washed their hands, Dr. Radhakrishnan picked up the intercom to Building 1. "Are you getting any signals from the chip?" he said. He asked the question out of purely academic interest; supposedly there was as bit of random electrical activity in the brain after death. "It's been dead for a couple of minutes,"

Zeldo said. "Completely dead?"

"Completely dead. We didn't think to include a surge protector."

"Surge protector?"

"Yeah. To protect the chip from sparks and lightning bolts, you know."

"I haven't seen any lightning."

"You held the lightning in your hands. You shocked him, man. That jolt from the defibrillator blew our chip to kingdom come." They did a postmortem more or less on the spot. A sterile environment was not required for an autopsy, so they part.i.tioned off one corner of the room to prevent other patients from seeing what was happening, and Dr. Radhakrishnan took Mr. Easyrider apart, piece by piece, paying special attention to the head.

Building 2 was a distracting work environment because it was full of head cases - old ones dying of natural causes and new ones being wheeled in all the time, from all over the subcontinent. Brain injury sometimes left people as vegetables, but in some cases it could cause bizarre behavior, and over the brief course of this project they had already seen their quota of screeches and headbangers. In the middle of Dr. Radhakrishnan's autopsy, they apparently brought in a new one. A loud, coa.r.s.e voice began to echo off the tin ceiling: "WUBBA WUBBA WUBBA WUBBA WUBBA WUBBA WUBBA WUBBA . . .".

It was no worse than a room full of excited baboons. He continued working, narrating his observations into a tape recorder; but he had to speak a little more loudly now because underneath his words was a constant background noise of WUBBA WUBBA WUBBA WUBBA WUBBA . . .The cause of death was obvious enough. Mr. Easyrider's body had rejected the implant. Dr.

Radhakrishnan tried to be clinical about it.

WUBBA WUBBA WUBBA WUBBA . . . "The organic portion of the biochip shows p.r.o.nounced atrophy ..."

WUBBA WUBBA WUBBA WUBBA . . . "The inorganic or silicon portion of the biochip is virtually rattling around loose inside the skull . . ." That was not very scientific. He took a deep breath.

WUBBA WUBBA WUBBA WUBBA WUBBA WUBBA WUBBA WUBBA . . .

"There is considerable scarring and atrophy in the portions of the brain adjacent to the implant." His head was spinning. He was tired. He just wanted to sit down and have a drink. "Conclusion: the host rejected the graft."

He was becoming conscious of another irrelevant sensory input besides the stream of WUBBAs: he was smelling perfume. It was not something that would really pa.s.s for perfume in India, where people knew as much about tastes and smells as Americans knew about heavy metal music. This was some kind of tedious lavender-and-roses concoction, something stupid and English.

"It appears that necrosis started at the site of the implant and spread to the brainstem - leading to the patient's demise." WUBBA WUBBA WUBBA WUBBA . . . "Doc?" someone said. Zeldo.

He looked up at Zeldo, feeling very tired. Zeldo had pulled the curtain aside and was now gaping at the b.l.o.o.d.y, dismembered corpse of Mr. Easyrider. He was not a medical person and was not inured to this kind of thing.

Dr. Radhakrishnan turned to face Zeldo, b.u.mping the table with his hip. The hemisphere of Mr.

Easyrider's skull rocked back and forth a little bit on the tabletop.

"Two things," Zeldo said.

"Yes?"

WUBBA WUBBA WUBBA WUBBA . . .

"There's a problem with Scatflinger. And there's a lady here to see you."

All of a sudden, the fact that he had gotten up at three in the morning was really getting to Dr.

Radhakrishnan.

Maybe these were simple problems, easy to fix. He emerged from the autopsy room still wearing his rubber gloves, smeared with blood and gray matter. If this was just going to take a minute, there was no point in getting ungloved and then regloving later. "First things first," he said, and led Zeldo toward the room that, as of this morning, Mr. Scatflinger now had all to himself.

As he approached the door, the sound of WUBBA WUBBA WUBBA grew louder.

No. It couldn't be.

He opened the door. Half of his staff was gathered around the bed.

Mr. Scatflinger, who had been unable to do anything except he in bed since his accident, was now sitting bolt upright in bed.

He had been totally aphasic as well, unable to make a sound. But now he was saying, "WUBBA WUBBA WUBBA WUBBA" as loudly as he could.

Everyone was looking at Dr. Radhakrishnan to see how he was going to react.

"Well," he said to his staff, "I think one can make the case that being able to say 'WUBBA WUBBA' is better than not being able to say anything at all, and that, at least in a limited sense, we have done Mr.

Scatflinger here a great service."

"Excuse me! Are you the gentleman in charge?" someone said. It was a lady's voice. Not just a female voice, but really a lady's voice.

Dr. Radhakrishnan turned around slowly, half-paralyzed by an unexplainable sense of fear and loathing.

The odor of lavender and roses was quite strong now.

He was looking directly into a bosom of Himalayan proportions, stoutly contained in some kind of undergarment and covered with a flowery print dress. His gaze traveled from the bottom to the top of thebosom, changing focus the whole way, and then encountered a soft, pale, yet st.u.r.dy neck. Above that was a face.
