Using Imagery to Change Your Brain
Q: Is there any evidence that just reading the words which describe an experience will bring activity to the corresponding part of the brain?
A: There is a lot of fMRI research in which the prompt to the subject in the scanner is reading a text. Many of the texts used are emotion words or passages. So there are many examples of reading producing brain activity that is consistent with the experience the subject reports while reading the text.
More specifically, if you mean reading about an experience per se, I don’t know of any specific studies about that, but there well may be. Bottom-line, if you read about an experience – say, a memoir of combat or rock-climbing or bar-hopping or commodities trading . . . or similar passages in fiction – and have a sense of that experience yourself while reading about it in someone else, then apart from the hypothetical influences of transcendental factors, by definition that mental experience must map one-to-one to underlying neural activity, and in the regions of the brain that represent that kind of experience (e.g., right hemisphere for imagery).
A parallel to reading would be imagining different experiences or behaviors, and you might be interested in Sharon Begley’s book, Train Your Mind, Change Your Brain, in which she reports a study that piano players who simply imagined playing a certain piece of music for sustained periods grew cortex in motor regions of the brain that handled those particular finger movements.
