Responses vary in autistic brains

摘要

Autism may emerge from a general unreliability of neuronal responses in the brains cortex, rather than from a deficiency in one particular brain area or circuit.Ilan Dinstein at Carnegie Mellon University in Pittsburgh, Pennsylvania, and his colleagues studied 14 people with autism and 14 people without the disorder. The researchers used functional magnetic resonance imaging to monitor cortical responsiveness as they stimulated the participants' sight, hearing and touch in dozens of trials.
