Ways to study the Brain

What is brain ablation?

• A method to enhance brain function
• The surgical removal or destruction of brain tissue
• A technique to improve memory
• A type of brain imaging

What is a common misconception about brain ablation?

• It is a reversible procedure.
• It is only used for psychological disorders.
• It has no impact on brain function.
• It is a surgical technique.

What is brain lesioning?

• A method to improve cognitive abilities
• The surgical removal of brain tissue
• The study of brain damage effects
• The process of enhancing brain function

What is the main purpose of studying brain lesions?

• To understand brain functions and their effects
• To improve memory retention
• To enhance cognitive abilities
• To develop new surgical techniques

How did historical studies of the brain influence modern treatment methods?

• They only focused on psychological disorders.
• They led to the abandonment of surgical techniques.
• They provided insights into brain functions and treatment strategies.
• They have no influence on modern treatments.

What is one implication of studying brain lesions?

• It helps in understanding the recovery of brain functions.
• It eliminates the need for further research.
• It proves that all brain functions are independent.
• It allows for the development of new medications.

What is a common outcome of brain damage in relation to specific functions?

• All brain functions are unaffected.
• Patients may experience difficulties based on the damaged area.
• Brain damage always leads to complete recovery.
• Only physical functions are impacted.

How do brain ablation and brain lesioning differ?

• There is no difference between the two.
• Lesioning is a surgical procedure, while ablation is not.
• Ablation involves removal, while lesioning involves damage.
• Ablation is reversible, while lesioning is not.

What is the significance of the corpus callosum in split-brain surgery?

• It connects the two hemispheres of the brain
• It processes visual information
• It enhances memory
• It controls movement

What is the main finding of Sperry and Gazzaniga's research on split-brain patients?

• The left and right hemispheres have identical functions
• The left hemisphere specializes in language and the right in spatial tasks
• Both hemispheres are equally responsible for all tasks
• The right hemisphere controls the left side of the body only
