The following is an excerpt.
How do the faulty brain circuits involved in mental disorders such as autism or retardation develop? Researchers at Weill Cornell Medical College have helped light the way to an answer with the discovery of a mechanism that guides the wiring of neural circuits in a developing brain.
The researchers discovered that faulty wiring occurs when RNA molecules embedded in a growing axon are not degraded after they give instructions that help steer the nerve cell.
