Brain-Computer Interface Quiz

What is the primary function of a Brain-Computer Interface (BCI)?

• To diagnose neurological disorders

• To improve cognitive abilities

• To control devices using brain signals

• To enhance memory retention

Who is Dr. Rajesh Rao and what is his contribution to the field of BCIs?

• A neuro engineer working on non-invasive BCI devices

• A surgeon specializing in brain surgeries

• A neuroscientist developing invasive BCI devices

• A computer scientist creating AI for BCIs

How does an EEG cap function in the context of BCIs?

• It measures heart rate during mental tasks

• It enhances brain signals for better memory

• It records brain signals to control devices

• It stimulates brain activity for learning

What is the difference between EEG and electrocorticography in BCIs?

• Electrocorticography is surgically placed on the brain surface

• EEG provides clearer signals than electrocorticography

• Electrocorticography is used for heart monitoring

• EEG is invasive, electrocorticography is non-invasive

What potential does the brain have when using BCIs with practice?

• It can learn to control unfamiliar prosthetics

• It can enhance sensory perception

• It can increase its size and capacity

• It can develop new neural pathways for speech
