Split-Brain Research AQA

Who conducted the split-brain research?

• Sperry and Gazzaniga

• Epilepsy patients

• Smith and Western

• Neuro-surgery participants

What was the aim of the split-brain research?

• To investigate language production

• To control extreme epilepsy seizures

• To study the corpus callosum

• To investigate the impact of separating the two hemispheres of the brain

What was the method used in the split-brain research?

• Observational study

• Case study

• Field experiment

How many participants were there in the split-brain research?

• 12

• 11

• 10

• 9

What did the split-brain research reveal about language processing?

• Language processing is not localised

• Language processing is mainly localized in the right hemisphere

• Language processing is evenly distributed across both hemispheres

• Language processing is mainly localized in the left hemisphere

What did the split-brain research show about recognition by touch?

• Recognition by touch is mainly processed by the left hemisphere

• Recognition by touch is mainly processed by the right hemisphere

• Recognition by touch is not affected by split-brain surgery

• Recognition by touch is evenly distributed across both hemispheres

What is the conclusion of the split-brain research?

• There is no evidence for hemispheric lateralisation

• There is evidence for hemispheric lateralisation and localisation of function

• Split-brain surgery has no cognitive side effects

• Seizures can be completely controlled by separating the hemispheres

What is the practical application of the split-brain research?

• To develop new epilepsy medications

• To improve cognitive function in split-brain patients

• To further our understanding of the nature of brain function

• To study the corpus callosum

What does the split-brain research imply about the brain?

• The brain has two identical hemispheres

• The brain has two functionally different hemispheres

• The brain functions as a single unit

• The brain is not affected by epilepsy

What did Gazzaniga propose about consciousness following split-brain study?

• Consciousness is evenly distributed across both hemispheres

• Consciousness is mainly localized in the left hemisphere

• Consciousness is mainly localized in the right hemisphere

• Consciousness is affected by epilepsy
