Modulation via mixed ion-electron conducting polymers

Modulation? She immediately began scanning the section. Did they really solve modulation?!

One of the most daunting hurdles in the quest to build an artificial neuron was to mimic “ion modulation”—a neuron’s unique ability to activate and deactivate sodium ion channels. And yet if this header was to be believed, ion modulation was now possible.

But…how?!

Heart racing, Katherine began reading about Threshold’s solution to the modulation problem. Everything about it made perfect sense to her…almost too perfect…and the further she read, the harder it became for her to breathe.

No…no…this can’t be!

“Katherine?” Langdon repeated, having joined her at the table after hearing her gasp a few moments ago. “Are you okay?”

But she made no reply, her eyes riveted to the binder as she flipped pages, one after another, muttering quietly to herself.

Langdon peered over her shoulder, trying to see what was upsetting her, but the page header meant nothing to him. Modulation via mixed ion-electron conducting polymers?

As the seconds wore on, Langdon sensed Katherine was in a state of mild shock, and he finally placed a hand on her arm. “What is it?”

She spun abruptly toward him, her eyes full of fire. “What is it? Threshold is using synthesized BBL as an organic electrochemical transistor! They cast it into a thin film and dissolved it in methanesulfonic—”

“Slow down—what?”

“BBL! They’re using it in the artificial neurons! That was my idea, Robert!”

“First of all, what is BBL?”

“Benzimidazobenzophenanthroline. It’s a highly conductive polymer that is uniquely tough and also elastic.”

“Okay, and…?”

“And they are implementing polycondensation to synthesize BBL—which was my suggestion. The result is a substance that is vastly conductive to electrons…much like a neuron.” She flipped a page of the binder. “Look! The chemical protocols in this binder are exactly the protocols I describe in my manuscript! Down to the finest details! I suggested modifying conductance by adding three millimolars of glutamine to the electrolyte solution—and that’s exactly what they are doing!”

Langdon wasn’t following much of this, but clearly Katherine believed she had identified a point of direct intersection between her manuscript and the Threshold project. That’s what we came here for.

“Katherine,” he said quietly, “can you take a breath and explain to me, in simple English, what’s going on?”

She nodded, exhaling. “Sorry, yes,” she said, lowering her voice. “Simply stated, my book theorized how this technology might actually be produced someday. I specifically proposed weaving the fabricated substance into a neural ‘mesh’ that could be pulled over the brain like a cap…a sheath of neurons in direct contact with the brain.” She sighed. “And…most incredibly, that is exactly what they are doing here. I just…well, I can’t believe it.”

“So you wrote expressly about artificial neurons?”

“I did. When I proposed a hypothetical brain chip to regulate GABA, I knew the chip could not be built without artificial neurons, so I included my best guess at how neurons might be fabricated someday…in the distant future.”

That future is apparently now, Langdon realized, glancing down at the binder. “And you think Threshold actually built the GABA chip you proposed?”

“No, no,” she said, shaking her head. “I have no idea what chip they built—but I’m pretty certain it would not be the one I proposed. If they have artificial neurons, the sky’s the limit; they could build literally whatever they dream up. Artificial neurons are the critical leap required for full H2M integration. You’ve got to understand, Robert…” She looked him straight in the eyes. “This neuron technology is the key to the future. It changes everything.”

Langdon had no doubt she was correct; he had read more than once that futurists predicted an artificial neuron breakthrough would usher in an astonishing era of direct brain-to-brain communication, memory augmentation, accelerated learning, and even the ability to record our dreams at night and play them back in the morning.

Most disturbing to Langdon, however, was the forecast hailed as “the ultimate social media”—humans making full-sensory recordings of their own experiences…and sharing their own personal “channels” directly with other minds. In essence, people would be able to relive the sights, sounds, smells, and feelings of someone else’s experience. Of course, it would not take long for black-market libraries to offer particularly shocking, titillating, or grisly memories. The 1990s cyberpunk movie Strange Days had ventured into this dark world…presciently, it now seemed.

Even though Langdon recognized this could well be a turning point in science history, the momentous impact of the breakthrough was not foremost in his mind. He was far more focused on the ramifications of Katherine’s incredible bad luck.

She proposed an inconceivably brilliant idea in her book…only to learn the CIA is already secretly developing it.

While the coincidence was stunning, Langdon knew the cliché “Great minds work alike” had been borne out countless times through the ages; Newton and Leibniz independently invented calculus; Darwin and Wallace simultaneously envisioned evolution; Alexander Graham Bell and Elisha Gray both invented a telephone device and filed patents within hours of each other. Now, it seemed, Katherine Solomon and the CIA had both figured out how to make artificial neurons.

“This all makes sense now…” Katherine whispered to herself, staring absently into space. “It’s no wonder I was targeted…”
