V.S. Ramachandran (UC San Diego) explains how his interest in Autism Spectrum Disorders (ASD) stems from an earlier, and broader, interest in mirror neurons and their dysfunction (and restitution of function) in neurology. He begins with a brief survey of the mirror neuron system (MNS) and then makes specific predictions of what to expect from their dysfunction in neurological populations with stroke or phantom limbs, as well as neurotypical populations who overlap with ASD.
