Informed Consent in Implantable BCI Research: Identifying Risks and Exploring Meaning.

Area of Science:

• Neuroscience
• Biomedical Engineering
• Bioethics

Background:

• Implantable brain-computer interface (BCI) technology is advancing rapidly towards clinical use.
• Ethical considerations, particularly informed consent, are paramount for BCI research participants.
• The evolving nature of BCI presents unique challenges in identifying and communicating risks.

Purpose of the Study:

• To identify and categorize core risk domains associated with implantable BCI research.
• To inform the development of robust informed consent processes for BCI studies.
• To highlight risks beyond standard safety and privacy concerns.

Main Methods:

• Review of existing literature and ethical frameworks in BCI and related neurotechnologies.
• Identification of risk domains through analysis of current BCI research challenges.
• Drawing parallels with risk assessment in deep brain stimulation research.

Main Results:

• Six core risk domains identified: short/long-term safety, cognitive/communicative impairment, unrealistic expectations, involuntariness, affective impairment, privacy/security.
• Three additional risk domains identified: risks to identity, agency, and potential for stigma.
• Current consent processes may not adequately address these comprehensive risks.

Conclusions:

• Comprehensive risk disclosure is essential for meaningful informed consent in implantable BCI research.
• Ethical frameworks must evolve to encompass risks related to identity, agency, and stigma.
• Engaging participants in exploring the meaning of BCI research is vital for ethical practice.
