Neuroethics is a field that explores the ethical implications of neuroscience, the study of the brain and nervous system. It addresses questions about how advancements in brain research can affect our understanding of free will, privacy, and personal identity. As technologies like brain imaging and neurostimulation evolve, they raise important moral considerations regarding their use and potential consequences. This discipline also examines the ethical treatment of individuals with neurological disorders and the implications of neuroenhancement—using technology to improve cognitive functions. By analyzing these issues, neuroethics aims to guide responsible practices in neuroscience and ensure that scientific progress aligns with societal values.
