Of all the stuff I came to do as a neuroscience undegrad there is one thing I particularly like to brag about. I shone lasers into mice brains, sliced them (brain, not mice) and created pretty fluorescent pictures out of them. Isn’t this the coolest opener at a party?
The way to have this kind of fun is called optogenetics and it is one of the hottest techniques in neuroscience right now. Pioneered by Karl Deisseroth of the Stanford University, this method is spreading like a wildfire through the neuroscience world and that for a good reason. As the name already suggests, genetical and optical technology are at play there. Gene technology is used to make specific cells light-sensitive, that is, to make them activate (or to shut down) when light falls on them and optical methods (=light) are used to subsequently manipulate these cells. This is done by the following steps:Read More
