Scientific advances in neuroscience and neurotechnology have led to significant achievements for humanity. These developments rely on the collection, storage, processing, and modification of neural data. As neurotechnologies improve and become more accessible, they may extend beyond the medical field - governed by strict standards - to broader consumer, workplace, education, criminal justice, and military applications.
