Questions
Which states have neural data privacy laws?
Colorado, California, Montana, Connecticut, Delaware and Vermont. Delaware's provisions take effect January 1, 2027 and Vermont's January 1, 2028.
Does an EMG wristband count as neural data?
In Colorado, California and Montana it can, because their definitions include the peripheral nervous system. Connecticut, Delaware and Vermont cover the central nervous system only.
Do consumer EEG headsets fall under these laws?
They can. The definitions turn on measuring nervous-system activity, not on whether the device is a medical implant. Medical data already covered by HIPAA and some research uses may be exempt under each act's general rules.
Is there a federal neural data law?
No. The MIND Act of 2025 would direct a study of neural data, not regulate it, and has not advanced.
