11 Psych Imaging techniques

Describe the human participants used in Sperry’s split-brain experiments.

• Adults with epilepsy who had undergone surgery

• Children with learning disabilities

• Adults with no medical history

• Teenagers with speech disorders

Outline the findings Sperry made in relation to speech production.

• Speech is controlled by the right hemisphere

• Both hemispheres equally control speech

• Speech is controlled by the left hemisphere

• Speech is not related to brain hemispheres

Provide the conclusion Sperry made in terms of the importance of the corpus callosum.

• It is not important for brain function

• It connects the two hemispheres for communication

• It is only important for motor skills

• It is responsible for memory storage

What is the function of the corpus callosum in the brain?

• Controls speech production

• Provides transfer of information between the hemispheres

• Regulates emotions

• Controls motor skills

Which hemisphere of the brain controls speech production?

• Right hemisphere

• Both hemispheres

• Left hemisphere

• Neither hemisphere

What happens to patients who have their corpus callosum severed?

• They lose all memory

• They cannot transfer information between hemispheres

• They become unable to speak

• They lose motor skills

List three side effects many patients who had a frontal lobotomy experienced.

• Memory loss, personality changes, and seizures

• Improved concentration, increased energy, and better mood

• Enhanced creativity, sharper vision, and faster reflexes

• Weight gain, hair loss, and improved digestion

Which of the following methods is used to measure electrical activity in the brain?

• Computed axial tomography (CAT)

• Magnetic resonance imaging (MRI)

• Electroencephalography (EEG)

• Functional magnetic resonance imaging (fMRI)

What does MRI stand for in medical imaging?

• Magnetic resonance imaging

• Magnetic radiation imaging

• Magnetic radio imaging

• Magnetic resonance inspection

Which imaging technique is specifically used to observe brain function by detecting changes associated with blood flow?

• Electroencephalography (EEG)

• Computed axial tomography (CAT)

• Magnetic resonance imaging (MRI)

• Functional magnetic resonance imaging (fMRI)
