Split Brain Research

What is the main finding of split brain research?

• Language production is strictly localized in the left hemisphere

• Language comprehension is strictly localized in the left hemisphere

• Both language production and comprehension are weakly localized in the left hemisphere

• Language production and comprehension are equally distributed in both hemispheres

What was the aim of the split brain research conducted by Sperry and Gazzaniga?

• To investigate the connection between the left and right hemispheres

• To study the effects of epilepsy on language production

• To determine the dominant hemisphere for language comprehension

• To understand how the two hemispheres function independently

What technique was used to project stimuli to either the left or right eye of the participants?

• MRI scanning

• Electroencephalography (EEG)

• Transcranial magnetic stimulation (TMS)

• Flashing stimuli on a board

What did participants experience when a picture of a spoon was shown to their left visual field?

• They could describe the object accurately

• They could pick the spoon with their right hand

• They could pick the spoon with their left hand

• They were unable to perceive the spoon

What does the research suggest about language comprehension?

• It is strictly localized in the left hemisphere

• It is weakly localized in the right hemisphere

• It is a function of both hemispheres

• It is not present in split brain patients

What did participants do when a simple word was flashed to their right hemisphere?

• They could describe the word accurately

• They could pick the corresponding object

• They could spell the word with their left hand

• They were unable to respond

What is lateralization in the context of split brain studies?

• The division of functions between the left and right hemisphere

• The localization of language production in the left hemisphere

• The specialization of brain areas due to neuroplasticity

• The distribution of memory functions in the brain

Which of the following is an example of a strictly localized function?

• Memory

• Speech production

• Speech comprehension

• Motor control

Which component of language seems to be more localized?

• Language production

• Language comprehension

• Memory of language

• Motor control of language

What does the research suggest about the respecialization of brain areas?

• Brain areas can respecialize due to neuroplasticity

• Brain areas remain static and do not respecialize

• Respecialization only occurs in split brain patients

• Respecialization is limited to language functions
