Neuroethicists engage in the philosophical, legal, and societal issues emerging from advances in neuroscience and neurology. They examine the ethical implications of brain-based technologies, neuroenhancement, cognitive liberty, and patient autonomy in neurodegenerative and psychiatric disorders. These experts navigate complex questions around consent, identity, personhood, and responsibility when cognitive function is impaired. Their insights shape guidelines for brain-machine interfaces, AI-assisted diagnostics, and emerging neurotechnologies. Working at the crossroads of bioethics, neurology, and law, neuroethicists advise research institutions, policymakers, and clinical teams on best practices. They participate in public dialogues about the societal impact of neuroscientific discoveries, from brain imaging in criminal law to predictive genetic testing for mental illness. Neuroethicists also advocate for equity in access to neurological care and protection of vulnerable populations. As neurotechnology rapidly evolves, their role ensures that innovation aligns with ethical responsibility and human dignity.
