Mirror neurons in autism


A ScienceDaily item (here) reports the work of I. Dinstein on mirror neurons. It seems that they may not be magical mindreaders after all.

A team of neuroscientists has found that the mirror neuron system, which is thought to play a central role in social communications, responds normally in individuals with autism. Their findings, reported in the journal Neuron, counter theories suggesting that a mirror system dysfunction causes the social difficulties exhibited by individuals with autism…

For the simulation process to work properly, it is imperative that we simulate the exact same movement we are observing. This means that neurons within our mirror system must recognize movements and respond with a unique, movement-selective, response to each (or else we’ll confuse different movements and attribute improper goals to the person we’re observing)…

Because individuals with autism have difficulty communicating socially and understanding the emotions and intentions of others, it has been hypothesized that they may have a dysfunction in their mirror neuron system. This hypothesis has received a tremendous amount of attention in both the popular and scientific literatures following a number of studies that reported weak mirror neuron system responses in individuals with autism. …

These results, they conclude, argue strongly against the “dysfunctional mirror system hypothesis of autism” because they show that mirror system areas respond normally in individuals with autism. The authors, therefore, suggest that it may be more productive to re-focus autism research in more promising directions.

  1. Autism has a strong genetic basis, although the genetics of autism are complex and it is unclear whether ASD is explained more by rare mutations, or by rare combinations of common genetic variants.,^,*
