Optogenetics: What is it? What can it do? What to expect in the future? Build an understanding from the fundamentals of life science. This article is aimed to help you understand the new technology of Optogenetics from the fundamentals of biology so that you can build knowledge, rather than accumulate discrete facts. All explanations have been included under a heading, so feel free to skip the ones you are already familiar with. Some instances of how a conclusion was arrived at have also been discussed through experiments so that you can understand the inner workings of scientific laboratories.
