they hear their native language (both parts are in Broca’s area). In contrast, bilinguals who learned their second language early in life showed activation in the same part of the brain, regardless of whether they were hearing their second language or their native one (Kim, Relkin, & Lee, 1997; also see Chee et al., 1999). This is evidence that early in life the language center of the brain is quite flexible at attuning itself to various kinds of linguistic input. After the sensitive period starts to close, however, those regions of the brain are no longer as capable of being restructured to accommodate the new language
(also see related work by Perani, Paulesu, & Galles, 1998). The most compelling kind of evidence that one could gather to test whether humans.

It is or so and then try to teach the unfortunate subjects a language and measure their performance. This is sometimes called the “forbidden experiment,” and you’ll be happy to know.
