Thanks for the post and introducing optogenetics! I remember the first time I heard about optogenetics (it was in C. elegans) I was just as excited as you. Here is optogenetics in action to control C. elegans movement (not humans or mice but the same technology is used).
It is an amazing field and in addition to activating or inactivating neurons, researchers have used optogenetics (light) to efficiently kill off cells.
For those who want some history of this field here is an review article.
Love Genetics (and optogenetics)
Cheers!
