“A Light Revolution in Neuroscience”

“New Technique Sheds Light on the Function Of Specific Neurons”

“Historically, neuroscientists have had a range of tools to manipulate and observe neural circuits in the brain. These techniques, however, have often lacked the ability to isolate the contribution of specific neurons or types of neurons to the overall network. With optogenetics, researchers can now discretely control neuronal activity by using pulses of light to activate or inactivate specific populations of neurons. These tools are giving neuroscientists the potential to unlock many of the remaining mysteries of how individual groups of cells in the brain control perception and behavior.”
