A Scanner Darkly Part 9

"I have no opinion. One way or another." Fred rose from his chair to leave.

"You're not splitting yet," Hank said, motioning him to reseat himself. He fished among the papers on his desk. "I have a memo here-"

"You always have memos," Fred said. "For everybody."

"This memo," Hank said, "instructs me to send you over to Room 203 before you leave today."

"If it's about that anti-drug speech I gave at the Lions Club, I've already had my a.s.s chewed about it."

"No, this isn't that." Hank tossed him the fluttery note. "This is something different. I'm finished with you, so why don't you head right over there now and get it done with."

He found himself confronting an all-white room with steel fixtures and steel chairs and steel desk, all bolted down, a hospital-like room, purified and sterile and cold, with the light too bright. In fact, to the right stood a weighing scale with a sign HAVE TECHNICIAN ONLY ADJUST. TWO HAVE TECHNICIAN ONLY ADJUST. TWO deputies regarded him, both in full uniform of the Orange County Sheriffs Office, but with medical stripes. deputies regarded him, both in full uniform of the Orange County Sheriffs Office, but with medical stripes.

"You are Officer Fred?" one of them, with a handle-bar mustache, said.

"Yes, sir," Fred said. He felt scared.

"All right, Fred, first let me state that, as you undoubtedly are aware, your briefings and debriefings are monitored and later played back for study, in case anything was missed at the original sessions. This is SOP, of course, and applies to all officers reporting in orally, not you alone."

The other medical deputy said, "Plus all other contacts you maintain with the department, such as phone contacts, and additional activities, such as your recent public speech in Anaheim to the Rotary Club boys."

"Lions," Fred said.

"Do you take Substance D?" the left-hand medical deputy said.

"That question," the other said, "is moot because it's taken for granted that in your work you're compelled to. So don't answer. Not that it's incriminating, but it's simply moot." He indicated a table on which a bunch of blocks and other riff-raff colorful plastic objects lay, plus peculiar items that Officer Fred could not identify. "Step over here and be seated, Officer Fred. We are going to administer, briefly, several easy tests. This won't consume much of your time, and there will be no physical discomfort involved."

"About that speech I gave-" Fred said.

"What this is about," the left-hand medical deputy said, as he seated himself and produced a pen and some forms, "stems from a recent departmental survey showing that several undercover agents working in this area have been admitted to Neural Aphasia Clinics during the past month."

"You're conscious of the high factor of addictiveness of Substance D?" the other deputy said to Fred.

"Sure," Fred said. "Of course I am."

"We're going to give you these tests now," the seated deputy said, "in this order, starting with what we call the BG or-"

"You think I'm an addict?" Fred said.

"Whether you are an addict or not isn't a prime issue, since a blocking agent is expected from the Army Chemical Warfare Division sometime within the next five years."

"These tests do not pertain to the addictive properties of Substance D but to- Well, let me give you this Set-Ground Test first, which determines your ability readily to distinguish set from ground. See this geometric diagram?" He laid a drawn-on card before Fred, on the table. "Within the apparently meaningless lines is a familiar object that we would all recognize. You are to tell me what the ..."

Item. In July 1969, Joseph E. Bogen published his revolutionary article "The Other Side of the Brain: An Appositional Mind." In this article he quoted an obscure Dr. A. L. Wigan, who in 1844 wrote: The mind is essentially dual, like the organs by which it is exercised. This idea has presented itself to me, and I have dwelt on it for more than a quarter of a century, without being able to find a single valid or even plausible objection. I believe myself then able to prove-(1) That each cerebrum is a distinct and perfect whole as an organ of thought. (2) That a separate and distinct process of thinking or ratiocination may be carried on in each cerebrum simultaneously.

In his article, Bogen concluded: "I believe [with Wigan] that each of us has two minds in one person. There is a host of detail to be marshaled in this case. But we must eventually confront directly the princ.i.p.al resistance to the Wigan view: that is, the subjective feeling possessed by each of us that we are One. This inner conviction of Oneness is a most cherished opinion of Western Man. ..."

"... object is and point to it in the total field."

I'm being Mutt-and-Jeffed, Fred thought. "What is all this?" he said, gazing at the deputy and not the diagram. "I'll bet it's the Lions Club speech," he said. He was positive.

The seated deputy said, "In many of those taking Substance D, a split between the right hemisphere and the left hemisphere of the brain occurs. There is a loss of proper gestalting, which is a defect within both the percept and cognitive systems, although apparently apparently the cognitive system continues to function normally. But what is now received from the percept system is contaminated by being split, so it too, therefore, fails gradually to function, progressively deterioriating. Have you located the familiar object in this line drawing? Can you find it for me?" the cognitive system continues to function normally. But what is now received from the percept system is contaminated by being split, so it too, therefore, fails gradually to function, progressively deterioriating. Have you located the familiar object in this line drawing? Can you find it for me?"

Fred said, "You're not talking about heavy metals trace deposits in the neuroreceptor sites, are you? Irreversible-"

"No," the standing deputy said. "This is not brain damage but a form of toxicity, brain toxicity. It's a toxic brain psychosis affecting the percept system by splitting it. What you have before you, this BG test, measures the accuracy of your percept system to act as a unified whole. Can you see the form here? It should jump right out at you."

"I see a c.o.ke bottle," Fred said.

"A soda pop bottle is correct," the seated deputy said, and whipped the drawing away, replacing it with another.

"Have you noticed anything," Fred said, "in studying my briefings and like that? Anything slushed?" It's the speech, he thought. "What about the speech I gave?" he said. "Did I show bilateral dysfunction there? Is that why I've been hauled in here for these tests?" He had read about these split-brain tests, given by the department from time to time.

"No, this is routine," the seated deputy said. "We realize, Officer Fred, that undercover agents must of necessity take drugs in the line of duty; those who've had to go into federal-"

"Permanently?" Fred asked.

"Not many permanently. Again, this is percept contamination that could in the course of time rectify itself as-"

"Murky," Fred said. "It murks over everything."

"Are you getting any cross-chatter?" one of the deputies asked him suddenly.

"What?" he said uncertainly.

"Between hemispheres. If there's damage to the left hemisphere, where the linguistic skills are normally located, then sometimes the right hemisphere will fill in to the best of its ability."

"I don't know," he said. "Not that I'm aware of."

"Thoughts not your own. As if another person or mind were thinking. But different from the way you would think. Even foreign words that you don't know. That it's learned from peripheral perception sometime during your lifetime."

"Nothing like that. I'd notice that."

"You probably would. From people with left-hemisphere damage who've reported it, evidently it's a pretty shattering experience."

"Well, I guess I'd notice that."

"It used to be believed the right hemisphere had no linguistic faculties at all, but that was before so many people had screwed up their left hemispheres with drugs and gave it-the right-a chance to come on. To fill the vacuum."

"I'll certainly keep my eyes open for that," Fred said, and heard the mere mechanical quality of his voice, like that of a dutiful child in school. Agreeing to obey whatever dull order was imposed on him by those in authority. Those taller than he was, and in a position to impose their strength and will on him, whether it was reasonable or not.

Just agree, he thought. And do what you're told.

"What do you see in this second picture?"

"A sheep," Fred said.

"Show me the sheep." The seated deputy leaned forward and rotated the picture. "An impairment in set-background discrimination gets you into a heap of trouble-instead of perceiving no forms you perceive faulty forms."

Like dog s.h.i.t, Fred thought. Dog s.h.i.t certainly would be considered a faulty form. By any standard. He ...

The data indicate that the mute, minor hemisphere is specialized for Gestalt perception, being primarily a synthesist in dealing with information input. The speaking, major hemisphere, in contrast, seems to operate in a more logical, a.n.a.lytic, computerlike fashion and the findings suggest that a possible reason for cerebral lateralization in man is basic incompatibility of language functions on the one hand and synthetic perceptual functions on the other.

... felt ill and depressed, almost as much as he had during his Lions Club speech. 'There's no sheep there, is there?" he said. "But was I close?"

"This is not a Rorschach test," the seated deputy said, "where a muddled blot can be interpreted many ways by many subjects. In this, one specific object, as such, has been delineated and one only. In this case it's a dog."

"A what?" Fred said.

"A dog."

"How can you tell it's a dog?" He saw no dog. "Show me." The deputy ...

This conclusion finds its experimental proof in the split-brain animal whose two hemispheres can be trained to perceive, consider, and act independently. In the human, where propositional thought is typically lateralized in one hemisphere, the other hemisphere evidently specializes in a different mode of thought, which may be called appositional appositional The rules or methods by which propositional thought is elaborated on "this" side of the brain (the side which speaks, reads, and writes) have been subjected to a.n.a.lyses of syntax, semantics, mathematical logic, etc. for many years. The rules by which appositional thought is elaborated on the other side of the brain will need study for many years to come.

In fact it was a specific type of dog: a greyhound, with drawn-in gut. had been inscribed, and now Fred recognized it as the shape drawn within the lines on the front side. In fact it was a specific type of dog: a greyhound, with drawn-in gut.

"What's that mean," he said, "that I saw a sheep instead?"

"Probably just a psychological block," the standing deputy said, shifting his weight about. "Only when the whole set of cards is run, and then we have the several other tests-"

"Why this is a superior test to the Rorschach," the seated deputy interrupted, producing the next drawing, "is that it is not interpretive; there are as many wrongs as you can think up, but only one right. but only one right. The right object that the U.S. Department of Psych-Graphics drew into it and certified for it, for each card; that's what's right, because it is handed down from Washington.

"A federal clinic?" Fred said.

"Yes. Now, what do you see in this drawing, among these particular black and white lines?"

Death City, Fred thought as he studied the drawing. That is what I see: death in pluriform, not in just the one correct form but throughout. Little three-foot-high contract men on carts.

"Just tell me," Fred said, "was it the Lions Club speech that alerted you?"

The two medical deputies exchanged glances.

"No," the standing one said finally. "It had to do with an exchange that was-actually-off the cuff, in fact, just bulls.h.i.tting between you and Hank. About two weeks ago ... you realize, there's a technological lag in processing all this garbage, all this raw information that flows in. They haven't gotten to your speech yet. They won't in fact for another couple of days."

"What was this bulls.h.i.tting?"

"Something about a stolen bicycle," the other deputy said. "A so-called seven-speed bicycle. You'd been trying to figure out where the missing three speeds had gone, was that it?" Again they glanced at each other, the two medical deputies. "You felt they had been left on the floor of the garage it was stolen from?"

"h.e.l.l," Fred protested. "That was Charles Freck's fault, not mine; he got everybody's a.s.s in an uproar talking about it. I just thought it was funny."

BARRIS: (Standing in the middle of the living room with a great big new shiny bike, very pleased) (Standing in the middle of the living room with a great big new shiny bike, very pleased) Look what I got for twenty dollars. Look what I got for twenty dollars.

FRECK: What is it? What is it?

BARRIS: A bike, a ten-speed racing bike, virtually brand new. I saw it in the neighbor's yard and asked about it and they had four of them so I made an offer of twenty dollars cash and they sold it to me. Colored people. They even hoisted it over the fence for me. A bike, a ten-speed racing bike, virtually brand new.

When the optic chiasm of a cat or a monkey is divided sagittally, the input into the right eye goes only into the right hemisphere and similarly the left eye informs only the left hemisphere. If an animal with this operation is trained to choose between two symbols while using only one eye, later tests show that it can make the proper choice with the other eye. But if the commissures, especially the corpus callosum, have been severed before training, the initially covered eye and its ipsilateral hemisphere must be trained from the beginning. That is, the training does not transfer from one hemisphere to the other if the commissures have been cut. This is the fundamental split-brain experiment of Myers and Sperry (1953; Sperry, 1961; Myers, 1965; Sperry, 1967).

... makes seven. So it's only a seven-speed bike.

LUCKMAN: Yeah, but even a seven-speed racing bike is worth twenty dollars. He still got a good buy. Yeah, but even a seven-speed racing bike is worth twenty dollars. He still got a good buy.

(They collectively wheel bike out front, right off encounter young black man parking his car. They point to the seven- eight? eight?-gears questioningly and ask how many there are, although they can see-except for Charles Freck-that there are only seven: five at one end of the chain, two at the other. Five and two add up to seven. They can ascertain it with their own eyes. What's going on?) YOUNG BLACK MAN: (Calmly) (Calmly) What you have to do is multiply the number of gears in front by the number in the rear.

All the evidence indicates that separation of the hemispheres creates two independent spheres of consciousness within a single cranium, that is to say, within a single organism. This conclusion is disturbing to some people who view consciousness as an indivisible property of the human brain. It seems premature to others, who insist that the capacities revealed thus far for the right hemisphere are at the level of an automaton. There is, to be sure, hemispheric inequality in the present cases, but it may well be a characteristic on the individuals we have studied. It is entirely possible that if a human brain were divided in a very young person, both hemispheres could as a result separately and independently develop mental functions of a high order at the level attained only in the left hemisphere of normal individuals.

... laughs.) laughs.) "We know you were one of the people in that group," the seated medical deputy said. "It doesn't matter which one. None of you could look at the bike and perceive the simple mathematical operation involved in determining the number of its very small system of gear ratios." In the deputy's voice Fred heard a certain compa.s.sion, a measure of being kind. "An operation like that const.i.tutes a junior high school apt.i.tude test. Were you all stoned?"

"No," Fred said.
