If we install these molecules in neurons somehow, then these neurons would become electrically drivable with light, and their neighbors, which don't have this molecule, would not.
Ja mēs varētu ievietot šīs molekulas kaut kādā veidā neironos, tad šie neironi kļūtu elektriski vadāmi ar gaismu. Un to kaimiņi, kuriem nav šīs molekulas, nekļūtu.
