Four US states now cover brain-activity data under existing privacy laws; federal bill pending

Colorado, California, Montana and Connecticut have enacted laws treating neural data as sensitive or protected data, in force between August 2024 and July 2026. Bills in Illinois and other states, and the federal MIND Act, which would fund a $10 million FTC study, are proposed but not passed.

The framing"Newest frontier" does fit a field where four US states enacted neural-data laws from 2024 and Congress saw its first neurotechnology bill in 2025. But most of those laws fold neural data into existing privacy statutes, the FTC Act already reaches its misuse, and Chile protected neural privacy in 2021.

What the headline leaves out

  • Most state laws add neural data to existing privacy statutes rather than create new regimes; the FTC Act already covers deceptive use.
  • Chile amended its constitution in 2021; Canada gave national protection in February 2026.
  • Coverage differs: Colorado excludes employees; California excludes stress inferred from heart rate.
  • Counts of states vary because sources mix enacted laws with pending bills.

What happens next

Connecticut's law took effect on July 1, 2026, joining Colorado, California and Montana. The MIND Act remains unpassed and would require a one-year FTC study before any binding guidance; the UK ICO's Robert McCombe said it targets early 2027 for draft neurodata guidance for consultation. Neuroethicist Rommelfanger, cited by IAPP, warned that Chile's broad definitions risked interfering with clinical treatment.

Possible knock-on effects
  • As more states act, neurotech companies may engage through lobbying or trade associations, which could shape definitions in later laws. (named expert: Arnold & Porter advisory, July 2025. Watch for: Industry testimony or trade-association comments on Illinois HB 2984 or the MIND Act.)
  • Broad legal definitions of neural data could constrain clinical uses, which may prompt medical groups to seek carve-outs. (precedent: Chile's 2021 constitutional amendment; clinicians' concerns cited by Rommelfanger via IAPP. Watch for: Medical exemptions added to pending state bills or AMA follow-up on Resolution 503.)

The report: what outlets said

According to the IAPP, "as neurotechnology advances, organizations face evolving privacy obligations for collecting, processing and protecting neural data."[1]

The IAPP reports that the Federal Trade Commission Act empowers the U.S. FTC to pursue unfair or deceptive trade practices, which can include collection, use and sharing of neural data.[1] The IAPP adds that some FTC rules, such as the Health Breach Notification Rule, are also likely to apply to the collection of neural data.[1]The IAPP also says the FTC's regulatory power is constrained by its inability to directly regulate medical devices[1]. It says that power is also limited by the case-by-case manner in which unfair or deceptive trade practices tests are applied.[1]At the state level, Sigma Law Group reports that Connecticut expanded its Data Privacy Act to treat neural data as sensitive[2]. According to PrivacyOn, Connecticut joins Colorado, California, and Montana[3] in protecting brain data.KFF Health News reports that Colorado and Montana require initial express consent to collect or use neural data and separate consent or the ability to opt out before disclosing that data to a third party.[4]Outside the U.S., the IAPP reports that Canada's privacy commissioner added neural data among the types of personal information that will generally be considered sensitive[5]. According to a separate IAPP report, the U.K. Information Commissioner's Office is targeting early 2027 to send neurodata privacy guidance out for public[6] consultation.The IAPP also quotes OECD policy analyst Christina Michelakaki, who said that "effective governance should be risk-based, context-specific, innovation-friendly and privacy protective."[6]
