Wernicke's area
Wernicke's area is a part of the human brain which forms part of the cortex, on the left posterior section of the superior temporal gyrus, posterior to the primary auditory cortex, on the tempero-parietal junction (part of the brain where the temporal lobe and parietal lobe meet).

Approximate location of Wernicke's area highlighted in blue
It can also be described as the posterior part of Brodmann area 22.
It is usually located on the left hand side, as the majority of people have brain areas specialised for language skills located on the left.
It is named after Karl Wernicke, a German neurologist and psychiatrist who discovered that damage to this area could cause a type of aphasia (now called Wernicke's aphasia or receptive aphasia) which results in an impairment of language comprehension, and speech which has a natural sounding rhythm but has a jumbled syntax is seems without recognisable meaning (a condition sometimes called fluent or jargon aphasia).
Wernicke's work initiated the study of this brain area and its role in language. It is particularly known to be involved in the understanding and comprehension of spoken language.
It is connected to Broca's area by a neural pathway called the arcuate fasciculus.
