Optogenetics: History & Applications

Optogenetics is a biological technique used to characterize and manipulate the activity of neurons or other cell types with light. This is achieved by expression of light-sensitive ion channels, pumps or enzymes in the target brain cells. A specialization of this field is nano-optogenetics.
