What is a challenge in reproducing the directional tone color of a violin through speakers?

• Speakers are too directional.

• Speakers amplify low frequencies too much.

• Speakers cannot handle high frequencies.

• Speakers lose the natural spatial effect.

How does the brain adapt to cochlear implants according to the transcript?

• By ignoring the new input.

• By rejecting the implant.

• By rerouting the input to resemble original sounds.

• By amplifying the input.

What is a downside of digitizing historical documents?

• It makes documents less accessible.

• It increases the risk of document loss.

• It leads to a loss of context and depth.

• It makes documents harder to read.

What is a potential benefit of using neuroscience in risk assessment?

• It can predict exact future actions.

• It provides a definitive answer to criminal behavior.

• It offers more insight into potential behavior.

• It eliminates the need for traditional assessments.

What is a challenge in using neuroscience for risk assessment?

• Neuroscience is too expensive.

• Neuroscience is not yet accurate enough.

• Neuroscience is too invasive.

• Neuroscience is not accepted by courts.

What is a key feature of modern MRI technology?

• It can only capture static images.

• It provides both structural and functional information.

• It is limited to brain imaging.

• It requires invasive procedures.

What is the analogy used to describe the difficulty in detecting planets?

• A shadow in the night.

• A needle in a haystack.

• A whisper in a storm.

• A firefly near a lighthouse.

What is the future potential of brain-machine interfaces according to the transcript?

• They will replace all current technology.

• They will remain invasive.

• They will be integrated into everyday devices.

• They will only be used for medical purposes.

What is the concept of 'sense of self' as discussed in the transcript?

• It is a fixed boundary defined by the body.

• It is a concept that cannot be changed.

• It is an arbitrary limit that can be expanded.

• It is determined by social interactions.

What does the transcript suggest about the nature of reality?

• Reality is solely based on physical objects.

• Reality is a construct of the brain.

• Reality is fixed and unchangeable.

• Reality is independent of human perception.
