<unk>  (BA<unk>  combined with Brodmann area 40 (BA 42) form Wernicke’s area in the superior temporal gyrus in the temporal lobe. Using cytoarchitectonics, BA<unk>  is located in the superior temporal gyrus which separates it from the primary and secondary auditory cortex. BA<unk>  is connected with nonverbal sound processing in the right hemisphere of the brain associated with activation in the auditory cortex. More functions associated with language in<unk>  include producing sentences, semantic processing, and processing of complex sounds. This area of the human brain supports lexical semantic processing and is responsible for language comprehension and production. Wernicke's area is shown to support lexical-semantics because lesions to this area result in difficulties displaying word selection during production of language. Wernicke's Aphasia Because Wernicke’s area supports language comprehension in the temporal lobe, lesions to the left auditory cortex, specifically in BA<unk> , results in Wernicke’s aphasia. Wernicke’s aphasia, also known as receptive aphasia, is a language disorder characterized as having difficulty comprehending language. This disorder varies in outcomes based on severity and localization of the brain damage, which is mostly commonly due to having a stroke. Patients diagnosed with Wernicke's aphasia are shown to have normal intonation and rate of speech, however have difficulty understanding different words of a language. Many individuals have poor awareness when making errors in speech, but are typically able to produce normal sentence structures when speaking. These sentences produced by patients with Wernicke's aphasia are often difficult for others to understand because of the problems with word selection and comprehension. These difficulties are shown at a lexical level, for example patients often struggle with naming figures due to accessing words from the lexicon.
