Foxp2, a gene involved in speech and language, helps regulate the wiring of neurons in the brain, according to a study which was published on July 7th in the open-access journal PLoS Genetics. The researchers identified this functional link by first identifying the major targets of Foxp2 in developing brain tissue and then analysing the function of relevant neurons. Foxp2 codes for a regulatory protein that provides a window into unusual aspects of brain function. In 2001, scientists discovered that mutations of the human gene cause a rare form of speech and language disorder...
