In California, brain sensors and implants are being used to control devices such as computers and wheelchairs. These devices can also predict productivity and suggest break times when paired with algorithms. The California Legislature is taking steps to regulate neurotechnology and brain data privacy.

Two years ago, lawmakers extended digital privacy law protections to include brain data. Further regulation is being considered, with bills aiming to restrict employer use of brain data and block the sale of sensitive personal information, including brain data, having made progress through the Assembly and Senate.
