   • Left frontal lobe

2. What is the primary function of Wernicke's area?

   • Motor control
   • Language comprehension
   • Speech articulation
   • Visual processing

3. The primary visual cortex is located in which lobe of the brain?

   • Parietal lobe
   • Occipital lobe
   • Temporal lobe
   • Frontal lobe

4. The somatosensory cortex, which processes touch, is located in which lobe?

   • The frontal lobe
   • The parietal lobe
   • The occipital lobe
   • The temporal lobe

5. Which structure connects the two cerebral hemispheres?

   • The hypothalamus
   • The cerebellum
   • The corpus callosum
   • The medulla oblongata

6. What term describes the brain's ability to reorganise itself after injury?

   • Plasticity
   • Transmission
   • Localization
   • Lateralisation

7. The primary motor cortex, which controls voluntary movement, is located in which lobe?

   • The temporal lobe
   • The frontal lobe
   • The parietal lobe
   • The occipital lobe

8. Damage to which brain area typically results in halting, non-fluent speech?

   • Wernicke's area
   • Visual cortex
   • Broca's area
   • Somatosensory area

9. A patient speaks fluently but produces meaningless words and struggles to understand what others say. Which area is most likely damaged?

   • The motor cortex
   • Wernicke's area
   • The corpus callosum
   • Broca's area

10. Why can split-brain patients not name objects seen in their left visual field?

    • Right hemisphere lacks speech
    • Corpus callosum transfers audio
    • Left hemisphere lacks vision
    • Optic chiasm is blocked

11. In most right-handed individuals, language functions are lateralised to which side?

    • Brain stem
    • Left hemisphere
    • Right hemisphere
    • Cerebellum

12. Surviving neurons taking over functions of damaged areas after a stroke is an example of what?

    • Synaptic pruning
    • Hemispheric lateralisation
    • Functional recovery
    • Sensory adaptation

13. Why is functional recovery after trauma greater in children?

    • Greater plasticity
    • Larger brain size
    • More neurons
    • Faster myelination

14. A patient with damage to the right parietal lobe draws only the left-hand halves of objects. What is this condition?

    • Blindsight
    • Split-brain syndrome
    • Hemispatial neglect
    • Broca's aphasia

15. Which cerebral lobe contains the primary auditory cortex?

    • Parietal lobe
    • Temporal lobe
    • Frontal lobe
    • Occipital lobe

16. What is a major limitation of Sperry's split-brain research?

    • High researcher bias
    • Small sample size
    • Poor ethical standards
    • Lack of standardisation

17. Which hemisphere controls language for the majority of people?

    • Left hemisphere
    • Both equally
    • Right hemisphere
    • Cerebellum

18. What suggests brain function involves networks rather than strict localisation?

    • Synaptic pruning
    • Distributed processing
    • Cortical mapping
    • Hemispheric dominance

19. Why does synaptic pruning peak during early childhood development?

    • High neural plasticity
    • Low metabolic rate
    • Reduced myelination
    • Decreased stimulation

20. What brain structure is surgically severed in split-brain patients?

    • Thalamus
    • Visual cortex
    • Corpus callosum
    • Motor cortex
