Measuring Brain Activity

The video discusses the capabilities of MRI in capturing both structural and functional brain images. It highlights the importance of resting state brain networks in understanding cognitive abilities and performance. The video also compares the brain connectivity of older monolingual and bilingual adults, showing that bilinguals have better connectivity in networks related to executive control.

What is the primary function of a functional coil in an MRI scanner?

• To measure the structural integrity of tissues

• To reveal brain activation during tasks

• To enhance the resolution of structural images

• To cool down the MRI machine

What is a key feature of resting-state networks in the brain?

• They are visible only in monolingual individuals

• They are unrelated to cognitive abilities

• They predict cognitive performance

• They are only active during sleep

How do resting-state networks contribute to our understanding of the brain?

• They are used to diagnose brain disorders

• They provide insights into brain organization and capabilities

• They are irrelevant to cognitive research

• They show how the brain functions during active tasks

What was a significant finding in the study comparing monolingual and bilingual older adults?

• Monolinguals had better memory networks

• Bilinguals showed better connectivity in executive control networks

• Bilinguals had weaker connectivity in vision networks

• Both groups had identical connectivity in all networks

In the study, what were participants instructed to do while in the MRI scanner?

• Engage in conversation with the researcher

• Solve puzzles to test memory

• Look at a blank screen and stay awake

• Perform a series of cognitive tasks
