Foxp2, a gene involved in speech and language, helps regulate the wiring of neurons in the brain, according to a study which will be 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...

Among 12- to 24-month old children who view educational baby videos, there does not appear to be evidence that overall general language learning improves or that words featured in the programming are learned, according to a report posted online today that will appear in the May print issue of Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals. Children age 2 and younger spend an estimated two hours per day exposed to media on a screen, and the average age at...

Psychologists at the University of Pennsylvania and the University of Memphis have released a new study on linguistic evolution that challenges the prominent hypothesis for why languages differ throughout the world. The study argues that human languages may adapt more like biological organisms than previously thought and that the more common and popular the language, the simpler its construction to facilitate its survival. Traditional thinking is that languages develop based upon random...

If humans are genetically related to chimps, why did our brains develop the innate ability for language and speech while theirs did not? Scientists suspect that part of the answer to the mystery lies in a gene called FOXP2. When mutated, FOXP2 can disrupt speech and language in humans. Now, a UCLA/Emory study reveals major differences between how the human and chimp versions of FOXP2 work, perhaps explaining why language is unique to humans. Published Nov. 11 in the online edition of the...

Scientists of the German Mouse Clinic at Helmholtz Zentrum Mnchen have generated and analyzed a mouse model in which parts of the human Foxp2 gene were introduced. Foxp2 is known to be a key gene for language. Since the human and chimpanzee lineages diverged, only minimal genetic alterations have occurred, even with reference to the mouse: The alterations, as scientists surmised, are closely associated with speech and language ability. However, proof on a functional level has been lacking...

German researchers have given mice the so-called "language gene" in an effort to understand the evolution of language. While the genetically-altered mice can't speak, they squeak differently and their brain circuits are measurably different "“ offering insight into how the gene works and how it evolved. The language gene, FOXP2, was first identified in 1998 when researchers discovered that members of a large family with a speech impediment had defective copies of the gene. The gene is...

CAMBRIDGE, Mass. "” The evolution of human speech was far more complex than is implied by some recent attempts to link it to a specific gene, says Robert Berwick, professor of computational linguistics at MIT. Berwick will describe his ideas about language in a session at the annual meeting of the American Association for the Advancement of Science on Sunday, Feb. 17. The session is called "Mind of a Toolmaker," and explores the use of evolutionary research in understanding human...

The Foxp2 gene plays an essential role in the development of social communication, according to a study led by researchers at Mount Sinai School of Medicine. The association between Foxp2 and language was first identified in a family in which half the members had severe speech and grammar impairments. Studies showed that all the affected family members had a mutation in the Foxp2 gene. The gene is found on a region of chromosome 7 that is linked to other disorders that affect speech,...
