Does a wider data stream out of the brain expose more of the mind?

More channels and richer features let a decoder find more than the one thing it was built for. Speech implants in motor cortex, designed to decode attempted speech, also picked up some inner speech during tasks such as counting, and the more of the raw signal leaves the head the more such secondary readings become possible later. Compressing data on the implant to only what one decoder needs is an engineering choice that also limits exposure, and ethicists have proposed safeguards of this kind, processing neural data where it is collected and sharing only what a service needs.
