lesions in which locations cause Broca’s aphasia?

inferior frontal gyrus / Broca’s area (BA 44 & 45)
frontoparietal operculum (in insula)
subcortical lesion

lesions in which locations cause Wernicke’s aphasia?

auditory cortex (BA 22)
angular gyrus (BA 39)
supramarginal gyrus (BA 40)

Wernicke’s area (BA 39 & 40)

lesions in which locations cause Conduction aphasia?

arcuate fasciculus (connects Broca’s to Wernicke’s)
supramarginal gyrus (BA 40)

lesions in which locations cause Global aphasia?

large lesion including Broca’s, Wernicke’s, and possibly more
sometimes Wernicke’s is spared
