Our results demonstrate that the natural image prior is a powerful (if unconventional) tool for mitigating the effects of these fundamental limitations. A natural image prior with only six million images is sufficient to produce reconstructions that are structurally and semantically similar to a target image.”
Brain-reading or Thought identification of Ethical issues
Criminal law
One potential area of application is criminal law. Haynes states that simply refusing to use brain scans on suspects also prevents the wrongly accused from proving their innocence.
US scholars generally believe that involuntary brain reading, and involuntary polygraph tests, would violate the 5th Amendment’s right to not self-incriminate. One perspective is to consider whether brain imaging is like testimony, or instead like DNA, blood, or semen.
Validity of using thought
In 2008 an Indian woman was convicted of murder after an EEG of her brain allegedly revealed that she was familiar with the circumstances surrounding the poisoning of her ex-fiancé. Some neuroscientists and legal scholars doubt the validity of using thought identification as a whole for anything past research on the nature of deception and the brain.
Privacy laws
The Economist cautioned people to be “afraid” of the future impact, and some ethicists argue that privacy laws should protect private thoughts. Legal scholar Hank Greely argues that the court systems could benefit from such technology, and neuroethics Julian Savulescu states that brain data is not fundamentally different from other types of evidence.
In Nature, journalist Liam Drew writes about emerging projects to attach brain reading devices to speech synthesizers or other output devices for the benefit of tetraplegics. Such devices could create concerns about accidentally broadcasting the patient’s “inner thoughts” rather than merely conscious speech.
