None of the 32 pig brains involved in the experiment showed any sign of the global electrical activity associated with consciousness. However, total reanimation, which would essentially bring the brain back from the dead, was never the goal. Reviving consciousness is both currently technologically unattainable and something the global scientific community agrees they should consider thoroughly––like using CRISPR to modify the human genome––before it’s attempted. It would have also gone against animal cruelty regulations that all U.S. federally-funded research must abide by. Although the chances of the brains becoming conscious were very slim, the team still took measures to avoid it. If there was any indication that a brain was becoming conscious, the team would have administered an anesthetic and cooled the brain enough to halt the process.
