"Wer zweisprachig aufwächst, hat eine dichtere graue Hirnsubstanz. Das Lernen einer zweiten Sprache scheine die Struktur des Gehirns zu verändern, berichten britische und italienische Forscherjetzt im Fachjournal Nature (Bd. 431). Die Beobachtung stütze die wachsende Zahl von Hinweisen darauf, dass sich die Struktur des Gehirns in Anpassung an Umweltanforderungen verändern kann. Cathy Price vom Wellcome Department of Imaging Neuroscience in London und ihre Mitarbeiter hatten die Gehirne von zweisprachigen mit denen von einsprachigen Menschenverglichen. Die zweisprachigen Probanden besaßen durchweg eine dichtere graue Substanz in einem Gehirnbereich, der für das flüssige Sprechen zuständig ist. Der Unterschied war umso größer, je eher die Untersuchten mit dem Lernen der zweiten Sprache begonnen hatten."
