Neuroenhancement refers to the use of various methods and substances to improve cognitive functions such as memory, attention, and creativity. This can include techniques like cognitive training, meditation, and the use of nootropic drugs, which are designed to enhance brain performance. The goal is to optimize mental capabilities and overall brain health. While some people seek neuroenhancement for academic or professional reasons, it raises ethical questions about fairness and safety. The long-term effects of many enhancement methods are still not fully understood, leading to ongoing debates in the fields of neuroscience and bioethics.
