• Driving the news: Neuroethicists are sounding the alarm.
• Earlier this month the U.K.'s Royal Society published a landmark report on the promise and risk of neurotechnology, predicting a "neural revolution" in the coming decades.
• And next month Chilean lawmakers will propose an amendment to the country's constitution enshrining protections for neural data as a fundamental human right, according to Yuste, who is advising on the process.
• A major concern is that brain data could be commercialized, the way advertisers are already using less intimate information about people's preferences, habits and location. Adding neural data to the mix could supercharge the privacy threat.
• "Accessing data directly from the brain would be a paradigm shift because of the level of intimacy and sensitivity of the information," says Anastasia Greenberg, a neuroscientist with a law degree.
