Implantable silicon chips
Wireless Bluetooth earbuds
Explanation - Focused ultrasound can modulate neural activity without opening the skull, lowering surgical risk.
Correct answer is: Non‑invasive focused ultrasound neuromodulation

Q.100 When a neuroengineer publishes data that could identify individual participants, which ethical principle is compromised?

Beneficence
Justice
Confidentiality (related to autonomy)
Non‑maleficence
Explanation - Revealing identifiable data breaches participant confidentiality and violates their autonomy.
Correct answer is: Confidentiality (related to autonomy)

Q.101 Which of the following best captures an ethical issue with “brain‑to‑brain communication” technologies?

Battery size
Potential loss of personal identity and consent for transmitted thoughts
Screen resolution
Cable length
Explanation - Direct transmission of thoughts may blur personal boundaries and raise consent concerns.
Correct answer is: Potential loss of personal identity and consent for transmitted thoughts

Q.102 A neurotechnology firm decides to discontinue a device after a safety issue is discovered but does not inform current users. This violates:

Beneficence
Non‑maleficence
Justice
Veracity
Explanation - Failing to disclose known risks is dishonest and puts users at risk.
Correct answer is: Veracity

Q.103 Which of the following is an ethical justification for restricting the use of neuroenhancement in academic testing?

To reduce device cost
To prevent unfair advantage and preserve the integrity of assessment
To increase battery life
To standardize device color
Explanation - Limiting enhancement maintains fairness and the validity of academic evaluation.
Correct answer is: To prevent unfair advantage and preserve the integrity of assessment

Q.104 In the context of neuroethics, “cognitive liberty” most directly opposes which practice?

Providing users with device manuals
Compulsory neural monitoring in the workplace without consent
Offering free device upgrades
Standardizing electrode shapes
Explanation - Cognitive liberty defends the right to control one’s own mental processes, opposing forced monitoring.
Correct answer is: Compulsory neural monitoring in the workplace without consent

Q.105 Which principle would require that a neural implant be designed to minimize potential harm even if it reduces performance?

Beneficence
Non‑maleficence
Justice
Autonomy
Explanation - Non‑maleficence prioritizes avoiding harm over achieving maximum performance.
Correct answer is: Non‑maleficence

Q.106 A neuroengineer suggests using a neural implant to subtly influence a user's political views. This raises concerns primarily about:

Battery capacity
Cognitive liberty and mental autonomy
Signal bandwidth
Device ergonomics
Explanation - Manipulating political views infringes on the individual's freedom of thought and autonomy.
Correct answer is: Cognitive liberty and mental autonomy

Q.107 Which emerging trend could increase the risk of inequitable access to neurotechnologies?

Open‑source hardware designs
High‑cost proprietary systems with limited insurance coverage
Standardized electrode sizes
Longer battery life
Explanation - Expensive, proprietary devices can be inaccessible to lower‑income populations, violating justice.
Correct answer is: High‑cost proprietary systems with limited insurance coverage

Q.108 When neural data is stored on cloud servers located in multiple jurisdictions, which ethical issue is most heightened?

Device overheating
Cross‑border data privacy and consent enforcement
Battery weight
Connector durability
Explanation - Different legal regimes can complicate protection of personal neural data.
Correct answer is: Cross‑border data privacy and consent enforcement

Q.109 Which principle would support giving participants the right to have their neural data deleted upon request?

Beneficence
Justice
Autonomy
Non‑maleficence
Explanation - Control over personal data is a key aspect of respecting individual autonomy.
Correct answer is: Autonomy

Q.110 A neurotechnology company markets a device as a ‘mind‑reading’ tool for personal relationships. The main ethical concern is:

Device battery life
Potential violation of privacy and consent within interpersonal contexts
Color of the device case
Ease of device cleaning
Explanation - Reading another person’s thoughts without consent intrudes on mental privacy and autonomy.
Correct answer is: Potential violation of privacy and consent within interpersonal contexts

Q.111 Which ethical principle is most relevant when a researcher decides to terminate a neuroclinical trial early due to unexpected adverse effects?

Beneficence
Justice
Non‑maleficence
Autonomy
Explanation - Stopping the trial prevents further harm to participants, aligning with the duty to do no harm.
Correct answer is: Non‑maleficence

Q.112 When a neuroprosthetic is designed to be upgradeable via software, which ethical safeguard should be prioritized?

Ensuring updates cannot be installed without explicit user consent
Choosing a bright device color
Using the cheapest components
Providing a longer warranty
Explanation - User consent for software changes protects autonomy and prevents unwanted alterations.
Correct answer is: Ensuring updates cannot be installed without explicit user consent
