“Even then, more than a year earlier, there were neurons in her head, not far from her ears, that were being strangled to death, too quietly for her to hear them. Some would argue that things were going so insiduously wrong that the neurons themselves initiated events that would lead to their own destruction. Whether it was molecular murder or cellular suicide, they were unable to warn her of what was happening before they died.”

“The well-being of a neuron depends on its ability to communicate with other neurons. Studies have shown that electrical and chemical stimulation from both a neuron's inputs and its targets support vital cellular processes. Neurons unable to connect effectively with other neurons atrophy. Useless, an abandoned neuron will die. ”

“Aya's eyes were vacant. But her lips were faintly trembling. Not from fear, but rather because she was whispering something under her breath. So quietly that no one else could hear, so quietly the sound did not even reach her own ears, over and over: 'I must save Masaki, I must save Masaki, I must save Masaki...”

“She stares at her knife and wishes she were smarter about things. Wishes she knew how to say something wise or consoling to him, something that wouldn't sound frightened or awkward. But then she remembers the time after her parents' death, when people would approach her and try to explain her loss to her; they said things that were supposed to cure her of her sadness, but that had no effect at all. And she knew then, even when she was nine years old, that there was no wise or consoling thing to say. There were certain helpful kinds of silences, and some were better than others. ”

“Back in 'my day' – though I didn't claim ownership of it at the time, this is what used to happen: you met a girl, you were attracted to her, you tried to ingratiate yourself, you would invite her to a couple of social events – for instance the pub – and then ask her out on her own, then again, and after a goodnight kiss of variable heat, you were somehow, officially, 'going out' with her. Only when you were semi-publicly committed did you discover what her sexual policy might be. And sometimes this meant her body would be as tightly guarded as a fisheries exclusion zone.”

“She would make facial expressions as though she were having conversations with people in her head.They seemed to turn into debates more often than not,judging by the activity on her forehead...It was almost the conversations in her head were loud enough to fill her silence.”
