Optogenetic approaches promise to revolutionize neuroscience by using light to
manipulate neural activity in genetically or functionally defined neurons with
millisecond precision. Harnessing the full potential of optogenetic tools,
however, requires light to be targeted to the right neurons at the right time.
Here we discuss some barriers and potential solutions to this problem. We review
methods for targeting the expression of light-activatable molecules to specific
cell types, under genetic, viral or activity-dependent control. Next we explore
new ways to target light to individual neurons to allow their precise activation
and inactivation. These techniques provide a precision in the temporal and
spatial activation of neurons that was not achievable in previous experiments. In
combination with simultaneous recording and imaging techniques, these strategies
will allow us to mimic the natural activity patterns of neurons in vivo, enabling
previously impossible 'dream experiments'.
