The powerful discipline of optogenetics can be described as “the branch of biotechnology which combines genetic engineering with optics to observe and control the function of genetically targeted groups of cells with light”. Using advanced laser beam-shaping such as Generalized Phase Contrast (GPC) and derived holographic modalities makes it possible to take advantage of cutting-edge two-photon technology to develop an unprecedented ‘circuit optogenetics’ platform with both high spatio-temporal selectivity and high penetration depth without disturbing speckle-noise. We will report on the latest laser shaping GPC-modalities with temporal focusing to uniquely sculpt patterns of one- and two-photon excitations for living neural-circuits and genetically modified light-sensitive cells.
