localisation of function Flashcards
What does localisation theory suggest?
Localisation theory suggests that certain areas of the brain are responsible for certain processes, behaviours and activities.
What is the function of the motor area?
The motor area, found in the frontal lobe, is involved in regulating and coordinating movements. Lesions or damage in the motor area result in an inability to control voluntary fine motor movements.
Where is the auditory area located and what is its function?
The auditory area is located in the temporal lobe on the superior temporal gyrus and is responsible for processing auditory information and speech. Lesions or damage in this area cause hearing loss, while damage to Wernicke’s area results in Wernicke’s aphasia.
What is the role of the visual area?
The visual area, located in the occipital lobe, is responsible for processing visual information.
What does the somatosensory area process?
The somatosensory area, located in the parietal lobe, processes information associated with the senses such as touch, heat, and pressure. Lesions in this area result in a loss of ability to denote sensitivity to particular bodily areas.
What is Wernicke’s Area responsible for?
Wernicke’s Area is responsible for speech comprehension and is located in the left temporal lobe for most people. Lesions or damage result in Wernicke’s aphasia, characterised by the use of nonsensical words and no awareness of using incorrect words.
What is the function of Broca’s Area?
Broca’s Area, located in the frontal lobe (usually in the left hemisphere), is responsible for speech production. Lesions or damage result in Broca’s aphasia, characterised by difficulty forming complete sentences and understanding sentence structure.
What is the overall association of the left hemisphere of the brain?
The left hemisphere of the brain is associated with language production and comprehension, making language a cognitive ability that is both localised and lateralised.
