Mia said, “So the mutated virus could still be extant and active.”
“Yes,” Kenin said. “We need not only neuro-images but a sample of cerebrospinal fluid. Her behavior suggests—”
“I know what her behavior suggests,” Mia said curtly. That sheer joy, shuddering in ecstasy… It was seizures in the limbic system, the brain’s deep center for primitive emotion, which produced such transcendent, rapturous trances. Religious mystics, Saul on the road to Damascus, visions of Our Lady or of nirvana. And the virus might still be extant, and not a part of the vaccine they had all received. Although if transmission was fetal, the medicians were safe. If not…
Mia said, “The rest of Esefeb’s behavior doesn’t fit with limbic seizures. She seems to see things that aren’t there, even talks to her hallucinations, when she’s not having an actual seizure.”
“I don’t know,” Kenin said. “There might be multiple infection sites in the brain. I need her, Mia.”
“We’ll be there,” Mia said, and wondered if that were going to be true.
But it was, mostly. Mia, after a brief uncomfortable sleep wrapped in the sheet of blue-green plastic, sat waiting for Esefeb to descend her rickety stairs. The girl bounced down, chattering at something to Mia’s right. She smelled worse than yesterday. Mia breathed through her mouth and went firmly up to her.
“Esefeb!” Mia pointed dramatically, feeling like a fool. The girl pointed back.
“Mia.”
“Yes, good.” Now Mia made a sweep of the sorry hut. “Efef.”
“Efef,” Esefeb agreed, smiling radiantly.
“Esefeb efef.”
The girl agreed that this was her home.
Mia pointed theatrically toward the city. “Mia efef! Mia eb Esefeb etej Mia efef!” Mia and Esefeb come to Mia’s home. Mia had already raided the computer’s tentative lexicon of Good Fortunese.
Esefeb cocked her head and looked quizzical. A worm crawled out of her hair.
Mia repeated, “Mia eb Esefeb etej Mia efef.”
Esefeb responded with a torrent of repetitious syllables, none of which meant anything to Mia except “Ej-es.” The girl spoke the word with such delight that it had to be a name. A lover? Maybe these people didn’t live as solitary as she’d assumed.
Mia took Esefeb’s hand and gently tugged her toward the door. Esefeb broke free and sat in the middle of the room, facing a blank wall of crumbling logs, and jabbered away to nothing at all, occasionally laughing and even reaching out to touch empty air. “Ej-es, Ej-es!” Mia watched, bemused, recording everything, making medical assessments. Esefeb wasn’t malnourished, for which the natural abundance of the planet was undoubtedly responsible. But she was crawling with parasites, filthy (with water easily available), and isolated. Maybe isolated.
“Lolimel,” Mia said softly into the wrister, “what’s the best dictionary guess for ‘alone’?”
Lolimel said, “The closest we’ve got is ‘one.’ There doesn’t seem to be a concept for ‘unaccompanied,’ or at least we haven’t found it yet. The word for ‘one’ is ‘eket.’ ”
When Esefeb finally sprang up happily, Mia said, “Esefeb eket?”
The girl look startled. “Ek, ek,” she said: no, no. Esefeb ek eket! Esefeb eb Ej-es!”
Esefeb and Ej-es. She was not alone. She had the hallucinatory Ej-es.
Again Mia took Esefeb’s hand and pulled her toward the door. This time Esefeb went with her. As they set off toward the city, the girl’s legs wobbled. Some parasite that had become active overnight in the leg muscles? Whatever the trouble was, Esefeb blithely ignored it as they traveled, much more slowly than yesterday, to Kenin’s makeshift lab in the ruined city. Along the way, Esefeb stopped to watch, laugh at, or talk to three different things that weren’t there.
“She’s beautiful, under all that neglect,” Lolimel said, staring down at the anesthetized girl on Kenin’s neuroimaging slab.
Kenin said mildly, “If the mutated virus is transmitted to a fetus, it could also be transmitted sexually.”
The young man said hotly, “I wasn’t implying—”
Mia said, “Oh, calm down. Lolimel. We’ve all done it, on numerous worlds.”
“Regs say—”
“Regs don’t always matter three hundred light years from anywhere else,” Kenin said, exchanging an amused glance with Mia. “Mia, let’s start.”
The girl’s limp body slid into the neuro-imager. Esefeb hadn’t objected to meeting the other medicians, to a minimal washing, to the sedative patch Mia had put on her arm. Thirty seconds later she slumped to the floor. By the time she came to, an incision ten cells thick would have been made into her brain and a sample removed. She would have been harvested, imaged, electroscanned, and mapped. She would never know it; there wouldn’t even be a headache.
Three hours later Esefeb sat on the ground with two of the guards, eating soysynth as if it were ambrosia. Mia, Kenin, Lolimel, and the three other medicians sat in a circle twenty yards away, staring at handhelds and analyzing results. It was late afternoon. Long shadows slanted across the gold-green grass, and a small breeze brought the sweet, heavy scent of some native flower.
Paradise, Mia thought. And then: Bonnet Syndrome.
She said it aloud, “Charles Bonnet Syndrome,” and five people raised their heads to stare at her, returned to their handhelds, and called up medical deebees.
“I think you’re right,” Kenin said slowly. “I never even heard of it before. Or if I did, I don’t remember.”
“That’s because nobody gets it anymore,” Mia said. “It was usually old people whose eye problems weren’t corrected. Now we routinely correct eye problems.”
Kenin frowned. “But that’s not all that’s going on with Esefeb.”
No, but it was one thing, and why couldn’t Kenin give her credit for thinking of it? The next moment she was ashamed of her petty pique. It was just fatigue, sleeping on that hard cold floor in Esefeb’s home. Esefeb efef. Mia concentrated on Charles Bonnet syndrome.
Patients with the syndrome, which was discovered in the eighteenth century, had damage somewhere in their optic pathway or brain. It could be lesions, macular degeneration, glaucoma, diabetic retinopathy, or even cataracts. Partially blind, people saw and sometimes heard instead things that weren’t there, often with startling clarity and realism. Feedback pathways in the brain were two-way information avenues. Visual data, memory, and imagination constantly flowed to and from each other, interacting so vividly that, for example, even a small child could visualize a cat in the absence of any actual cats. But in Bonnet syndrome, there was interruption of the baseline visual data about what was and was not real. So all imaginings and hallucinations were just as real as the ground beneath one’s feet.
“Look at the amygdala,” medician Berutha said. “Oh merciful gods!”
Both of Esefeb’s amygdalae were enlarged and deformed. The amygdalae, two almond-shaped structures behind the ears, specialized in recognizing the emotional significance of events in the external world. They weren’t involved in Charles Bonnet syndrome. Clearly, they were here.
Kenin said, “I think what’s happening here is a strengthening or alteration of some neural pathways at the extreme expense of others. Esefeb ‘sees’ her hallucinations, and she experiences them as just as ‘real’—maybe more real — than anything else in her world. And the pathways go down to the limbic, where seizures give some of them an intense emotional significance. Like… like orgasm, maybe.”
Ej-es.
“Phantoms in the brain,” Berutha said.
“A viral god,” Lolimel said, surprising Mia. His tone, almost reverential, suddenly irritated her.
“A god responsible for this people’s degradation, Lolimel. They’re so absorbed in their ‘phantoms’ that they don’t concentrate on the most basic care of themselves. Nor on building, farming, art, innovation… nothing. They’re prisoners of their pretty fantasies.”
