Page "Language acquisition" Paragraph 30

Although it is difficult to determine without invasive measures which exact parts of the brain become most active and important for language acquisition, fMRI and PET technology has allowed for some conclusions to be made about where language may be centered.

Kuniyoshi Sakai proposed, based on several neuroimaging studies, that there may be a " grammar center ", where language is primarily processed in the left lateral premotor cortex ( located near the pre central sulcus and the inferior frontal sulcus ).

Additionally, these studies proposed that first language and second-language acquisition may be represented differently in the cortex.
