The bilingual brain: Cerebral representation of languages

Franco Fabbro 2001

"When a second language is learned formally and mainly used
at school, it apparently tends to be more widely represented in the cerebral cortex
than the first language, whereas if it is acquired informally, as usually happens with
the first language, it is more likely to involve subcortical structures (basal ganglia
and cerebellum) (cf. Paradis, 1994; Fabbro & Paradis, 1995; Fabbro et al., 1997;
Fabbro, 2000)."

Right hemisphere is associated with pragmatics (Chantraine et al 1998)

L2 language processes (phonology, morphology, syntax) are not in the right hemisphere (Paradis 1994, 1998)

Klein et al. 1995 performed the first neuroimaging study on bilinguals

Translation and comprehension are subserved by different processes.
