Scientists implant "memories" into bird brains to teach them songs they've never heard
  • By activating light-sensitive proteins in the brains of zebra finches, scientists have taught these birds how to sing a song that they’ve never heard.
  • Only the length of syllables in the bird’s song was controlled -- areas responsible for other aspects of singing are yet to be uncovered.
  • It was achieved using optogenetics, which means using flashes light to stimulate neurons in the brain.
  • In the future, studies like this could eventually lead to new treatments for speech disorders in humans.
