The function of the arcuate fasciculus of the nondominant hemisphere is very little studied. It is thought to connect areas of the brain involved in the generation and understanding of [[language]]. ==Pathology== Damage to this pathway can cause a form of [[aphasia]] known as [[conduction aphasia]], where auditory comprehension and speech articulation are preserved, but people find it difficult to repeat heard speech. ==See also== * [[aphasia]] ==External links== * http://www.lib.mcg.edu/edu/eshuphysio/program/section8/8ch15/s8c15_14.htm * http://thebrain.mcgill.ca/flash/d/d_10/d_10_cr/d_10_cr_lan/d_10_cr_lan.html * http://brain.oxfordjournals.org/cgi/reprint/awh622v1.pdf {{White matter}} [[Category:Cerebrum]] [[Category:Neuroanatomy]] [[Category:Central nervous system pathways]] [[de:Fasciculus arcuatus]] [[ja:弓状束]]
