What is optogenetics and how does it work?
In 2005, a new technique was created, called optogenetics. This technique uses a combination of light and genetic engineering (changing the genetic information of a living thing by inserting or deleting information in the genetic code) to control the cells of the brain.
What is the use of optogenetics?
Unlike previously developed experimental methods of light control, optogenetics allows researchers to use light to turn cells on or off with remarkable precision and resolution (down to individual cells or even regions of cells) in living, freely moving animals.
Has optogenetics been used in humans?
Even though optogenetics is a relatively new neuromodulation tool whose various implications have not yet been scrutinized, it has already been approved for its first clinical trials in humans.
When was optogenetics first used?
Historically, the concept of optogenetics was conceived for neuroscience in 1979 with the suggestion from Francis Crick on the potential utility of light in providing rapid spatiotemporal control for targeting specific neurons; however, during that time neuroscientists did not know methods to apply such photosensitive …

What is needed for optogenetics?
Freely-Behaving Optogenetics There are three main components for freely-behaving experiments: an optical cannula, a fiber-optic cable, and a light source. As previously mentioned, the optical cannula is implanted into the region of interest expressing the optogenetic probe to illuminate light into the brain.
Who found optogenetics?
Karl Deisseroth of Stanford University and Ed Boyden of MIT are generally regarded as the inventors of optogenetics and many expect them to be future Nobel laureates.
What is optogenetics and why does it matter?
“Optogenetics is the ability to manipulate individual neuronal circuits, refining our vision of the function of individual circuits and how they relate to different aspects of our behaviour and personality,” she explains.
Is optoptogenetics the future of memory research?
Optogenetics is making great strides in the field of memory research, and it shows a great deal of potential. Although the creation and destruction of memories may sound dangerous, it also has great therapeutic potential for a wide variety of neuropsychiatric diseases.
Can optogenetics be used to treat depression?
In other words, optogenetics could be used to switch on the positive memories in the brain, thereby potentially curing the depression. This technique could also be used in the treatment of early stage Alzheimer’s, by switching on the cells of the brain that retrieve memories.
