The really important finding is that the brains of girls with autism are also operating differently from the brains of boys with autism. Scans showed that each autistic girl’s brain behaved more like that of a typical boy of the same age, which, compared to typical girls, has reduced activity in regions normally associated with socializing. The brain-activity measures of autistic girls would not be considered “autistic” in a boy. Instead, the brain of a girl with autism may be more like the brain of a typical boy than that of a boy with autism.
