Two-Photon Calcium Imaging of the Same Neurons Over 100 Days (image) RIKEN Share Print E-Mail Caption These are representative images of GCaMP6f fluorescent signals. Neurons indicated by yellow arrowheads were assumed to be the same between post injection day 10 and post injection day 118. Image depth was 200 μm from the cortical surface.
