happy.”
Rachel would snuggle contentedly beneath her blankets. The story, like any good fairy tale, had elements of tragedy. In the story, Rachel’s father worked at a university, studying the workings of the brain and charting the electric fields that the nervous impulses of an active brain produced. But the other researchers at the university didn’t understand Rachel’s father; they distrusted his research and cut off his funding. (During this portion of the story, Aaron’s voice took on a bitter edge.) So he left the university and took his wife and daughter to the desert, where he could work in peace.
He continued his research and determined that each individual brain produced its own unique pattern of fields, as characteristic as a fingerprint. (Rachel found this part of the story quite dull, but Aaron insisted on including it.) The shape of this “Electric Mind,” as he called it, was determined by habitual patterns of thoughts and emotions. Record the Electric Mind, he postulated, and you could capture an individual’s personality.
Then one sunny day, the doctor’s wife and beautiful daughter went for a drive. A truck barreling down a winding cliffside road lost its brakes and met the car head-on, killing both the girl and her mother. (Rachel clung to Aaron’s hand during this part of the story, frightened by the sudden evil twist of fortune.)
But though Rachel’s body had died, all was not lost. In his desert lab, the doctor had recorded the electrical patterns produced by his daughter’s brain. The doctor had been experimenting with the use of external magnetic fields to impose the patterns from one animal onto the brain of another. From an animal supply house, he obtained a young chimpanzee. He used a mixture of norepinephrin-based transmitter substances to boost the speed of neural processing in the chimp’s brain, and then he imposed the pattern of his daughter’s mind upon the brain of this young chimp, combining the two after his own fashion, saving his daughter in his own way. In the chimp’s brain was all that remained of Rachel Jacobs.
The doctor named the chimp Rachel and raised her as his own daughter. Since the limitations of the chimpanzee larynx made speech very difficult, he instructed her in ASL. He taught her to read and to write. They were good friends, the best of companions.
By this point in the story, Rachel was usually asleep. But it didn’t matter—she knew the ending. The doctor, whose name was Aaron Jacobs, and the chimp named Rachel lived happily ever after.
Rachel likes fairy tales and she likes happy endings. She has the mind of a teenage girl, but the innocent heart of a young chimp.

Sometimes, when Rachel looks at her gnarled brown fingers, they seem alien, wrong, out of place. She remembers having small, pale, delicate hands. Memories lie upon memories, layers upon layers, like the sedimentary rocks of the desert buttes.
Rachel remembers a blonde-haired fair-skinned woman who smelled sweetly of perfume. On a Halloween long ago, this woman (who was, in these memories, Rachel’s mother) painted Rachel’s fingernails bright red because Rachel was dressed as a gypsy and gypsies liked red. Rachel remembers the woman’s hands: white hands with faintly blue veins hidden just beneath the skin, neatly clipped nails painted rose pink.
But Rachel also remembers another mother and another time. Her mother was dark and hairy and smelled sweetly of overripe fruit. She and Rachel lived in a wire cage in a room filled with chimps and she hugged Rachel to her hairy breast whenever any people came into the room. Rachel’s mother groomed Rachel constantly, picking delicately through her fur in search of fleas that she never found.
Memories upon memories: jumbled and confused, like random pictures clipped from magazines, a bright collage that makes no sense. Rachel remembers cages: cold wire mesh beneath her feet, the smell of fear around her. A man in a white lab
