Wearable neurotech used to train AI brain models without consent
The gist
Science reported wearable neurotech firms trained AI brain models on users' EEG data without telling them.
The finding puts consent rules for neural data in the spotlight.
How it unfolded
- Jul 20, 2025CBS News reports states including Colorado, California and Montana have passed laws to protect neural data collected by devices.
- Apr 7, 2026The Conversation reports legal and ethical frameworks for consumer neurotech are struggling to keep up, citing a landmark case from Chile.
- Jul 1, 2026Connecticut classifies brain data as sensitive, requiring explicit, separate opt-in consent for sale of neural data.
