Wernicke's Area
Wernicke's area is classically located in the posterior section of the superior temporal gyrus of the dominant hemisphere (Brodmann area 22), with some branches extending around the posterior section of the lateral sulcus, in the parietal lobe.
Considering its position, Wernicke's area is located relatively between the auditory cortex and the visual cortex. The former is located in the transverse temporal gyrus (Brodmann areas 41 and 42), in the temporal lobe, while the latter is located in the posterior section of the occipital lobe (Brodmann areas 17, 18 and 19).
While the dominant hemisphere is in charge of most of language comprehension, recent studies have demonstrated that the less dominant (right hemisphere in 97% of people) homologous area participates in the comprehension of ambiguous words, whether they are written or heard.
Receptive speech has traditionally been associated with Wernicke's area of the posterior superior temporal gyrus (STG) and surrounding areas. Current models of speech perception include greater Wernicke's area, but also implicate a "dorsal" stream that includes regions also involved in speech motor processing.
First identified by Carl Wernicke in 1874, its main function is the comprehension of language and the ability to communicate coherent ideas, whether the language is vocal, written, signed.

Famous quotes containing the word area:
“Self-esteem is the real magic wand that can form a child’s future. A child’s self-esteem affects every area of her existence, from friends she chooses, to how well she does academically in school, to what kind of job she gets, to even the person she chooses to marry.”
—Stephanie Martson (20th century)
