The video explores how bilingualism affects brain biology, emphasizing the brain's plasticity. It explains that bilingualism rewires the brain, particularly enhancing the executive control system, which manages attention and conflict resolution. The video also highlights structural changes in bilingual brains, such as increased cortical thickness and better white matter integrity, which improve communication between brain regions.

What is the primary characteristic of the brain that allows it to adapt to new experiences like language learning?

• Rigidity

• Plasticity

• Stability

• Inflexibility

Which system in the brain is responsible for managing attention during linguistic interactions?

• Motor System

• Sensory System

• Executive Control System

• Limbic System

Which part of the brain is primarily involved in the executive function system?

• Temporal lobe

• Prefrontal lobe

• Occipital lobe

• Parietal lobe

How does bilingualism affect the distribution of brain networks?

• It localizes brain activity to one hemisphere.

• It creates a more distributed network across hemispheres.

• It reduces the use of frontal systems.

• It limits cognitive flexibility.

What structural change is observed in the brains of bilinguals compared to monolinguals?

• Reduced white matter

• Increased cortical density

• Decreased cortical thickness

• Less myelin coverage

What is the role of myelin in brain communication?

• It reduces neuron connectivity.

• It slows down signal transmission.

• It acts as a barrier between neurons.

• It speeds up signal transmission.

Which regions show better cortical density in bilinguals?

• Parietal regions

• Frontal regions

• Temporal regions

• Occipital regions
