The brain may be one of the most fascinating organs in the human body, and yet, we still haven’t fully unlocked its mysteries. However, with the advent of optogenetics, scientists now have a better chance of understanding how the brain works.

Genome editing used to be a long, laborious, and expensive process that, for quite a long time, you’d have been forgiven for thinking only worked on mice. In the earlier days, making a single genomic modification on a target organism could take a year or so and may have cost up to several hundreds of thousands of dollars to complete. Thankfully, these limitations were addressed with the development of powerful alternative bioengineering technologies, namely ZFN, TALENs, and CRISPR.
