CARTA (Center for Research and Anthropogeny) has a great collection of videos from their 10/5/12 symposium: Human Origins – Lessons from Autism Spectrum Disorders. The symposium featured Daniel Geschwind, Eric Courchesne, Andrew Meltzoff, Simon Baron-Cohen, and Bernard Crespi.
The hour-long video I’ve embedded features Karen Pierce (“The Early Identification of Autism: Examinations of Brain and Behavior”), Mirella Dapretto (“Mirroring in the Neurotypical and Autistic Brain”), and V. S. Ramachandran (“Mirror Neuron Dysfunction in Neurology”).
Since the extent to which mirror neurons are implicated in autism is subject to debate, here is a link to a recent review (“The functional role of the parieto-frontal mirror circuit: Interpretations and misinterpretations”) by Rizzolatti et al. for additional perspective.
