Wernicke's Area — Function, Location & Quiz
Wernicke’s area links heard language with meaning in the usually dominant posterior temporal cortex. It is commonly paired with Broca’s area, but their classic syndromes differ in both anatomy and the direction of failure: comprehension breaks down here while speech remains fluent.
Fluency can hide the severity of the deficit. A patient may produce effortless sentences that contain substitutions or invented words and may not recognize that the message is incomprehensible, making awareness another useful contrast with Broca’s aphasia.

Location and anatomical map
Language comprehension, speech understanding.
Atlas category: cortical. Brodmann areas or landmark: BA 22 (posterior superior temporal gyrus).
Functions
- Language comprehension — understanding speech
- Semantic processing of words and sentences
- Phonological processing and word recognition
- Interface between auditory input and meaning
Pathways and connections
- Arcuate fasciculus → Broca's area (production)
- Wernicke's ← Auditory cortex (sound input)
- Wernicke's ↔ Angular gyrus (reading comprehension)
Clinical relevance
- Wernicke's aphasia — fluent but meaningless speech, poor comprehension
- Patients unaware of their deficit (anosognosia for language)
- Neologisms and word salad: 'I want to gleep the frumpet zooly'
- Carl Wernicke (1874) described this after autopsy of aphasic patient
Key facts
- Wernicke-Geschwind model: arcuate fasciculus connects Wernicke's → Broca's
- Conduction aphasia: arcuate fasciculus damage → can't repeat but comprehension and production intact
- Modern view: language is more distributed than Wernicke-Geschwind model suggests
- fMRI shows Wernicke's area activates for both spoken and sign language
Exam tip
Wernicke's = fluent nonsense (they don't know it). Broca's = effortful but meaningful (they DO know it). Conduction = can't repeat.
Common questions
What does Wernicke’s area do?
It supports spoken-language comprehension, semantic processing, phonological recognition and the connection between auditory word forms and meaning.
Where is Wernicke’s area located?
It is classically placed in the dominant posterior superior temporal gyrus, usually on the left, and is associated with Brodmann area 22.
What does Wernicke’s aphasia sound like?
Speech is fluent but may be empty, incorrect or filled with neologisms, while comprehension is poor. Patients are often less aware of the deficit than people with Broca’s aphasia.
