It looks quite grotesque when mounted on the mice mind you. The “flourescent molecules” are by far the coolest, just google GFP (green flourescent proteins) and optogenetics - basically force specific behaviours or genetic expression in a mouse by shining light in the area you injected the optogenetic anitbodies.
We already develop drugs and perform a lot of research with the first techniques, example device here: https://open-ephys.org/miniscope-v4/miniscope-v4
