The Long Wire

The dog's name was Biscuit, and Biscuit had eaten a sock.

Soren knew this because his mother had said it three times into the phone, each time in a slightly more tired voice. Now Biscuit was sleeping off the anesthesia in the recovery kennel, and Soren was sitting on the cold floor outside it, waiting for his mother to finish her notes so they could go home.

The heart monitor beeped. On the screen above the kennel, a green line jumped and settled, jumped and settled.

"Why is it doing that fast part," Soren asked.

Dr. Okafor, the vet, was washing her hands at the sink and not really listening. "Doing what."

"The beeping. It sped up. Nothing happened."

Dr. Okafor glanced at the screen. "Her gut's waking up. The anesthesia slows everything down, then the digestion comes back online. The heart feels it."

Soren took out his notebook and wrote: heart feels the gut.

"How does the heart feel the gut," he said. "They're not next to each other."

"There's a nerve," Dr. Okafor said, drying her hands. "Big one. The vagus nerve. It runs from the brain all the way down past the heart and into the belly. Connects everything." She said it the way adults say things they have stopped finding strange. Then she went into the front to find a chart.

Soren stayed on the floor.

The word vagus sat in his head. He thought it sounded like a road. A long wire from the brain going down, and at the far end, the stomach, the intestines, all the soft machinery that had just tried to digest a sock.

He drew it. A line from a circle at the top down to a tangle at the bottom. He put an arrow on the line, pointing down. Brain at the top, giving orders. Stomach at the bottom, obeying. That was how it worked. The brain was in charge. The brain was always in charge.

The monitor sped up again.

Nothing had happened. Biscuit had not moved. No one had touched her. But the green line had quickened, and then a moment later her paw twitched and her breathing changed, like a decision had been made somewhere and the rest of her was finding out about it.

Soren watched the order of it. The gut first. Then the heart. Then the breath. Then the paw.

That was the wrong order.

If the brain was in charge, the brain should go first. The brain should decide, send the order down the wire, and the gut should answer. But the speeding up had started low, in the belly, where the digestion was switching back on. The signal had gone up. The body had found out second.

He looked at his drawing with the arrow pointing down. He turned the notebook over and drew it again, and this time he made himself be honest about the order he had actually seen. He drew the arrow pointing up.

Then he sat with it, because it felt wrong, and he wanted to know why it felt wrong.

Dr. Okafor came back through with a folder. "Still here," she said.

"The nerve," Soren said. "Does it only go down? Brain to stomach?"

She stopped. She actually looked at him this time. "Funny you ask. No. It goes both ways. But it's lopsided."

"Lopsided how."

"Most of the fibers go up." She held her hand out flat and tilted it. "Way more. Something like four out of five carry signals from the gut to the brain, not the other way. The belly's doing most of the talking. The brain's mostly listening."

Soren did not say anything for a second.

"Four out of five," he said.

"Roughly. It surprises people." She shrugged, already turning toward her desk. "We like to think the head runs the show. The wiring says different." Then her phone rang and she was gone again, sock-dog forgotten, on to the next thing.

Soren looked back at the monitor.

Four out of five. He had drawn one arrow, pointing down, and been wrong, and even his corrected arrow pointing up had been too simple, because the truth was both at once, just heavily one-sided. A wide road going up. A narrow road coming down. The brain at the top of a long wire, and most of what travelled that wire was news. The gut, reporting. The brain, mostly receiving.

He pressed his own hand against his own stomach, under his ribs, without meaning to.

Somewhere in there, right now, his own gut was doing the same thing Biscuit's was. Switching things on and off. Deciding, in its quiet wet machinery, what to send up the wire. And the part of him he thought of as himself, the part doing the thinking, the part holding the pen, was at the top of the wire getting the reports. Reading them. Finding out.

He had always assumed the order was: I decide, then my body does it. But the monitor had shown him the other order. The body, then the finding out. Sometimes the feeling came up the wire before he had any idea what it was. A sick feeling before he knew he was nervous. A settled feeling before he knew he was safe.

Most of the wire went up.

Most of him was listening to a part of him he never heard speak.

The monitor slowed. Biscuit sighed in her sleep, a long dog sigh, and her gut had decided that, not her dreams. The brain found out. The breath came after.

Soren wrote one line under his two drawings. He did not write what it meant. He wrote: who is telling who.

His mother came out pulling on her coat. "Ready? You look like you saw something."

"How do you know I'm ready," Soren said.

She laughed. "You're already standing up."

He looked down. He was. He hadn't decided to. His legs had gotten him up off the cold floor while the thinking part of him was still busy, and now the thinking part was finding out, the way it found out about everything, a half-second late, at the top of a long wire.

Biscuit's monitor beeped behind him, steady now, the green line climbing and settling, climbing and settling, reporting up from the dark warm belly to a brain that had no idea yet what it was about to feel.
