Heating, not highly non-linear photo damage is limiting for 920-nm 2-imaging
Unraveling how neural networks process and represent sensory information and how these cellular signals instruct behavioral output is a main goal in neuroscience. Two-photon activation of optogenetic actuators and calcium (Ca 2+) imaging with genetically encoded indicators allow, respectively, the all-optical… Continue reading
