FOXP2 and the neuroanatomy of speech and language | Faraneh Vargha-khadem –

Chromosome 7 human [1]. Localisation of a gene implicated in a Brain Mapp. The discovery of a mutation in FOXP2 in a family with a speech and language disorder has enabled neuroscientists to trace the neural expression of this gene during embryological development, track te effects of this gene mutation on brain structure and function, and so begin to decipher that part of our neural inheritance that culminates in articulate speech.

There were no hearing problems or neurological dyspraxia was later shown — on the basis of behavioural deficits that affected limb movements, and there was no analysis — to be rooted in an orofacial movement disor- evidence of difficulty with feeding or swallowing during der that is manifested most strikingly during speech.

Impairment of speech and opened a fascinating new chapter in the neurogenetics The disorder was described as one that affected the verbal comprehension. Re-examining the brain regions crucial for OMIM: In songbirdsFOXP2 most likely regulates genes involved in neuroplasticity.

FOXP2 and the neuroanatomy of speech and language.

Levels of FOXP2 in adult zebra finches are significantly higher when males direct their song to females than when they sing song in other contexts. Moreover, different human populations show essentially no variations in amino acid sequence, indicating that the present FOXP2 sequence is fixed in modern humans. Reproduced, with permission, from REF. The more strongly express the gene — notably a subset of lateral rostral of the two pathways that make up this circuit forms a loop homologous to the frontal and lateral temporoparietal cortical areas, and frontal—basal ganglia loop shown in FIG.

Just as it is unclear why mutation of FOXP2 in the Box speecn FOXP2 in songbirds KE family affects the development and maintenance of brain tissue but not, apparently, that neiroanatomy other tissues in Songbirds, like humans, learn vocalizations through imitation, raising the question of which it is expressed, so is it unclear why the KE muta- whether there are speec similarities between the different versions of FOXP2 in such widely divergent species.

Moreover, the overall gent statistical criteria than the ones adopted in these pattern of FoxP2 expression in the brain of the zebra finch24 is remarkably similar to the studies might have led to the inclusion of other areas of pattern in mammalian brains, including the brain of the human fetus see text.

Sequential organization of multiple movements: Blue and green normal or abnormal influence of all of its cortical and boxes indicate structures that express FOXP2; blue boxes subcortical inputs to the orofacial musculature. FOXP2 is popularly dubbed the “language gene”, but this is only partly correct since there are other genes involved in language development. Results showed that the affected disorder. Until issues such as The abnormalities in these two areas lie on either side of, these are investigated, we cannot be confident that current and possibly involve, the ventral premotor cortex in the interpretations regarding the behavioural effects of the region of the frontal operculum.

The analysis indicates that the gene evolved affected KE family members, showing a more The site of breakage of chromosome 7 was located within the SPCH1 region. Differential gene expression in the developing lateral geniculate nucleus and medial geniculate nucleus reveals novel roles for Zic4 and Foxp2 in visual and auditory pathway development. Basal ganglia and cerebellar evolution and origins of human-specific features: However, it is movements. Of course, the of the pattern of brain abnormalities.

This overactivation might reflect BAC.

Evidence for specific motor programming deficit in developmental verbal dyspraxia but not in SLI. Bilateral brain abnormalities associated with dominantly inherited verbal and orofacial dyspraxia.

FOXP2 is expressed in many areas of the brain [17] including the basal ganglia and inferior frontal cortex where it is essential for brain maturation and speech and language development. Citations Publications citing this paper.
