The possible role of asymmetric laryngeal innervation in language lateralization: points for and against.

Peters (1992) suggested that the asymmetry between the lengths of the left and right recurrent laryngeal nerves had been completely overlooked as a possible factor in the lateralization of hemispheric function. He has since (personal communication, 1993) acknowledged that this was incorrect insofar as Walker (1987a, 1988) had previously made very similar proposals to those contained in his article and the hypothesis that asymmetrical laryngeal innervation influences brain lateralization had been referred to by Bradshaw (1988). Corballis (1989) and Previc (1991) also discussed the possible relationship between lateralization and laryngeal innervation mentioned in Walker (1988).
