Localisation of Function Flashcards
What does localisation suggest about the brain?
Certain areas of the brain are responsible for specific processes, behaviours, and activities.
Where is the motor area located?
In the frontal lobe, seperated from the auditory area by the central sulcus.
What is the function of the motor area?
Regulates and coordinates movements.
What happens if the motor area is damaged?
Results in an inability to control voluntary fine motor movements.
Where is the auditory area located?
In the temporal lobe on the superior temporal gyrus.
What is the function of the auditory area?
Processing auditory information and speech.
What happens if the auditory area is damaged?
- General damage causes hearing loss.
- Damage to specific parts, like Wernicke’s area, causes Wernicke’s aphasia.
Where is the visual area located?
In the occipital lobe.
What is the function of the visual area?
Processing visual information.
Where is the somatosensory area located?
In the parietal lobe.
What is the function of the somatosensory area?
Processing sensory information such as touch, heat, and pressure.
What happens if the somatosensory area is damaged?
A loss of sensitivity in specific body areas.
What is Wernicke’s area responsible for?
Speech comprehension.
Where is Wernicke’s area located?
In the left temporal lobe.
What are the symptoms of Wernicke’s aphasia?
- Use of nonsensical words.
- Unaware of incorrect words used.
What is Broca’s area responsible for?
Speech production.
Where is Broca’s area located?
In the frontal lobe.
What are the symptoms of Broca’s aphasia?
- Difficulty forming complete sentences.
- Confusion with word order.
Which hemisphere is language production and comprehension typically associated with?
The left.
What does language typically being associated with the left hemisphere suggest?
Language is both localised and lateralised
