Neurotech companies are selling your brain data, senators warn

A growing concern has emerged about brain-computer interface (BCI) technologies, which collect vast amounts of neural data that could be misused without consent or control by users. Companies like Neuralink benefit from medical device classifications under HIPAA but lack clear policies on user consent and data ownership. Senators are urging stricter regulations to balance innovation with accountability, while some states have already passed consumer-protection laws for neural data.
