Optogenetics: Lighting up the brain enables surprising discoveries

摘要

Newer techniques like single-cell and holographic optogenetics allow neuroscientists to give every cell its own code and to project holograms into the brain. Optogenetics combines optics, genetics, and virology to allow researchers to use light to control brain cells genetically engineered to respond to specific wavelengths. It's revolutionized neuroscience by enabling researchers to shine light into the brains of animals to explore neural circuits and make surprising discoveries.
