However some technical challenges still need to be taken to make the technology more accessible and usable to its full potential: gaining selective and comprehensive genetic access to the neurons of interest, controlling variation in the expression of the optogenetic tools (when using viruses) and its precise localization (axon vs. presynaptic terminals), tailoring light - delivery system signals to individual cells in a population rather than the population as a whole, developing observation techniques which have the same spatial and temporal resolution as those tools... to cite only a few of them.
