Localisation of function in the brain Flashcards
What is the corpus callosum?
A bundle of nerve fibres that allows the two hemispheres to communicate
What is hemispheric lateralisation?
The division of functions between the two hemispheres
What does the left hemisphere control?
Language processing and visual information
What does the right hemisphere control?
Recognising emotion, spatial information and visual patterns
What does the motor cortex do?
Sends information to the muscles via the brain stem and spinal cord. Important for complex movements and non-basic actions, such as coughing and crying
What are the two language areas?
Broca’s and Wernicke’s
What is Broca’s area important for and who was the case study for this?
Speech production; Louis Leborgne
What is Wernicke’s area important for?
Speech comprehension
Which disorder used to be treated with a corpus callosotomy and why?
Epilepsy; to prevent a seizure spreading over both hemispheres, which is potentially fatal
Where is the visual cortex located?
The occipital lobe
Where is the motor cortex located?
The posterior of the frontal lobe
Where is the sensory cortex located?
The parietal lobe
Where is the auditory cortex located?
The temporal lobe
