October 2020: Publication from the Kara lab.

'Three-photon imaging of synthetic dyes in deep layers of the neocortex' published in Scientific Reports.

Liu et al. (2020) characterized the visual tuning properties of neurons in mouse V1 with OGB-1/AM. This is the first publication using a synthetic, small-molecule calcium indicator with 3-photon excitation. Their study includes characterization of the 3-photon cross sections for several common fluorophores.
