Define Localisation of Function
Refers to the principle that specific functions originate in certain regions of the brain
1 of 17
Where is the Visual Cortex located and what is it responsible for?
Occipital Lobe and is responsible for processing visual information. Nerve impulses are transferred from the retina to the visual cortex via optic nerves.
2 of 17
Where is the auditory cortex located and how does it work?
Temporal Lobe. Process starts at the cochlea which detects sound. Messages are transported to brain stem then onto the auditory cortex.
3 of 17
Where is the motor cortex located and what is it responsible for?
Frontal Lobe. Responsible for coordinating movement.
4 of 17
Where is the somatosensory cortex located and what does it do?
Parietal Lobe. Responsible for processing information related to touch eg. pressure.
5 of 17
What are the language centres called and what do each one of them do?
Broca's area (responsible for the production of language) and Wernicke's area (responsible for the understanding of language).
6 of 17
How can beta bias be used as an evaluation point for LOF?
Fails to take into account individual differences. Herastly found women have larger Broca's area. Suggests that different considerations are required.
7 of 17
What theory did Lashley propose and how does this cast doubt on LOF?
The equipotentiality theory which suggests higher functions aren't localised. Portrays LOF as being biologically reductionist by over-simplifying complex processes.

Dronkers (2007)
Conducted MRI scan on patient Tan's brain and found other areas of his brain were damaged so we cant confidently say that his speech was affected due to damage to Broke's area.

Petersen
Used brain scans to how how Wernicke's area was active during a listening task and Brocke's area is active during a reading task.
10 of 17
What is meant by the term plasticity?
The notion that the brain has the ability to adapt physically and functionally in response to new experiences.

Weisel
Sewed a kittens eye shut and found that the area of the visual cortex that is associated with the shut eye wasn't idle as expected and continued to process info from the other eye.
12 of 17
What are the nerve fibre that connected the two hemispheres of the brain called?
corpus callosum

Sperry and Gazzangia
Split-brain pps took part in 3 different visual tasks.
14 of 17
Explain why Sperry and Gazzangia found what they did.
Pps couldn't describe what was presented to their left visual field because the info is processed in the right hemisphere which doesn't have language input. Can be described on the right visual field.
15 of 17
What is a negative evaluation point of this study?
Only 11 pps were involved, all of which had history of epileptic seizures which may have caused unique changes in the brain that could influence the findings.
16 of 17
How does the lab environment benefit this study?
Standardised procedures eg. image flashed for 1/10 of a second which ensures that the info doesn't have the chance to speak across each hemisphere.
