As a graduate student at MIT, Steve Ramirez successfully created false memories in the lab. Now, as a neuroscientist working at the frontiers of brain science, he foresees a future where we can replace our negative memories with positive ones. In “How to Change a Memory,” Ramirez draws on his own memories—of friendship, family, loss, and recovery—to reveal how memory can be turned on and off like a switch, edited, and even constructed from nothing.
A future in which we can change our memories of the past may seem improbable, but in fact, the everyday act of remembering is one of transformation.
Intentionally editing memory to improve our lives takes advantage of the brain’s natural capacity for change.
In “How to Change a Memory,” Ramirez explores how scientists discovered that memories are fluid—they change over time, can be erased, reactivated, and even falsely implanted in the lab. Reflecting on his own path as a scientist, he examines how memory manipulation shapes our imagination and sense of self.
