Biopsychology- Localisation of Function Flashcards
What is the role of the motor cortex?
Controls voluntary movement
What is the role of the somatosensory cortex?
Processes information about touch, pain, temperature and proprioception
What is the role of Broca’s area?
Speech production
What is the role of the auditory cortex?
Processes information from our ears
What is the role of the visual cortex?
Processes information from our eyes
What is the role of Wernicke’s area?
Language comprehension
What are the 4 lobes of the brain?
Frontal, parietal, temporal, occipital
How is the brain divided?
Into left and right hemispheres
How are the two hemispheres connected?
By the corpus callosum
Where is Broca’s area located?
Left frontal lobe
Where is Wernicke’s area located?
Left temporal lobe
Where is the motor cortex located?
Frontal lobe
Where is the somatosensory cortex located?
Parietal lobe
What is the left hemisphere responsible for?
Language, logic, analysis, problem solving
What is the right hemisphere responsible for?
Spatial comprehension, emotions, facial recognition
What is the different hemispheres having different functions known as?
Hemispheric lateralisation of function
What was the method of Sperry’s study?
- Combination of case studies and experiments
- 11 participants who had undergone split brain surgery
- Control group used who hadn’t had split brain surgery
- Participants covered one eye and looked at a fixed point on a projection screen
- Pictures projected onto right or left of the screen
What was the results of Sperry’s study?
- If picture shown in right visual field then participants could say or write down
- If picture shown onto left then split brain participants couldn’t say or write what they’d seen
What was the conclusion from Sperry’s study?
Left hemisphere can convert sight into spoken and written language
