Optogenetics is a biological technique to control the activity of neurons or other cell types with light. This is achieved by expression of light-sensitive ion channels, pumps or enzymes specifically in the target cells. On the level of individual cells, light-activated enzymes and transcription factors allow precise control of biochemical signaling pathways.[1] In systems neuroscience, the ability to control the activity of a genetically defined set of neurons has been used to understand their contribution to decision making,[2] learning,[3] fear memory,[4] mating,[5] addiction,[6] feeding,[7] and locomotion.[8] In a first medical application of optogenetic technology, vision was partially restored in a blind patient with Retinitis pigmentosa.[9] Optogenetic techniques have also been introduced to map the functional connectivity of the brain.[10][11] By altering the activity of genetically labelled neurons with light and by using imaging and electrophysiology techniques to record the

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 . [ 1 ] On the level of indivi
