Figure 4. Different illumination strategies for optogenetic activation.

Figure 4

(a) Different cell types sensitized by different color opsins. (b) Activation of one (green) cell type using wide-field blue activation beam. (c) Activation of two (green and red) cell types using wavelength multiplexed beams (blue & green). (d) Activation of one (green) cell using focused blue activation beam. (e) Activation of multiple (green) cells using multiple blue activation beams. (f) Activation of one (green) and another (red) cell using focused blue and green activation beams.
