Optogenetics: Controlling the Brain with Light

This short blogpost illustrates optogenetics — a radical new technology for controlling brain activity with light that I recently rediscovered. Optogenetics is an emerging field of research that is combing ‘optics‘ with ‘genetics’ to modify the activities of brains.

Researchers genetically modify certain neurons to activate when they receive pulses of light. This is part of the medical field that is studying how to stimulate specific areas of the brain to relieve a host of chronic neurological aliments ranging from depression to Parkinson’s disease.

This post might be a bit ‘out-of-the-box’, and too research minded. But it think this interesting topic is worth mentioning. Impressive to see what the power of optics and light can do, especially related to the human body and brains. Finally, here’s a movie from MITTechTV explaining this new phenomenon in research:
