Temporal Lobe Flashcards
What are the two main areas contained in the temporal lobe?
The auditory cortex and Wernicke’s area
The auditory cortex processes sound, while Wernicke’s area is involved in language comprehension.
What is the function of the auditory cortex?
Processing sound
Damage to this area can lead to auditory agnosia, auditory hallucinations, or cortical deafness.
What is Wernicke’s area primarily responsible for?
Language comprehension
It is located in the dominant hemisphere, usually the left.
What condition results from damage to Wernicke’s area?
Wernicke’s aphasia
This is also known as receptive aphasia.
What are the symptoms of Wernicke’s aphasia?
- Impaired comprehension of written and spoken language
- Impaired repetition
- Anomia
- Fluent but incoherent or meaningless speech
Speech may include many word substitutions and errors.
What is the arcuate fasciculus?
A bundle of axons that connects Wernicke’s area to Broca’s area
Damage to this structure can lead to conduction aphasia.
What is conduction aphasia?
Characterized by relatively intact comprehension but fluent speech with many errors
It also involves impaired repetition and anomia.
True or False: Damage to the auditory cortex can lead to cortical deafness.
True
Cortical deafness is one possible consequence of auditory cortex damage.
Fill in the blank: Damage to Wernicke’s area results in _______.
Wernicke’s aphasia
This disorder affects language comprehension.
Where is Wernicke’s area located?
In the dominant (usually left) hemisphere
It is a major language area of the brain.
What is the result of damage to the arcuate fasciculus?
Conduction aphasia
This condition is characterized by relatively intact comprehension but fluent speech that contains many errors, impaired repetition, and anomia.
True or False: Wernicke’s aphasia is characterized by non-fluent speech.
False
Individuals with Wernicke’s aphasia have fluent speech.
