“…Leischner (1948) formulated a neurologie al theory of bilingualism "according to which there exists at the posterior edge of the Sylvian fossa and in the adjoining parietal regions of the brain a special language switching mechanism" (Weinreich, 1953, p. 72). This hypothesis of an anatomically localized control center has been criticized by other researchers and still requires experimental confirmation.…”

“…2 14 15 Subsequent studies have distinguished pathological switching and pathological mixing phenomena 34 Additional studies have established that pathological mixing is mainly due to lesions in the parietotemporal structures of the left hemisphere, whereas the nervous structures responsible for switching between languages have not been clearly described so far 5…”

Cerebral lesions may alter the capability of bilingual subjects to separate their languages and use each language in appropriate contexts. Patients who show pathological mixing intermingle diVerent languages within a single utterance. By contrast, patients aVected by pathological switching alternate their languages across diVerent utterances (a self contained segment of speech that stands on its own and conveys its own independent meaning). Cases of pathological mixing have been reported after lesions to the left temporoparietal lobe. By contrast, information on the neural loci involved in pathological switching is scarce. In this paper a description is given for the first time of a patient with a lesion to the left anterior cingulate and to the frontal lobe-also marginally involving the right anterior cingulate area-who presented with pathological switching between languages in the absence of any other linguistic impairment. Thus, unlike pathological mixing that typically occurs in bilingual aphasia, pathological switching may be independent of language mechanisms. (J Neurol Neurosurg Psychiatry 2000;68:650-652)

“…Clinical studies. The literature on aphasia in speakers of more than one language is replete with cases of differential loss or recovery of one or more of the languages the aphasia patients spoke prior to the trauma (Gloning & Gloning, 1965;Lebrun, 1976;Leischner, 1948;Minkowski, 1963;Nair & Virmani, 1973;Galloway, Note 3; see Paradis, 1977, for a review). This has led to the speculation that the languages of the bilingual or multilingual are differentially represented in the brain.…”
