Genetic Tagging of Subiculum Neurons (IMAGE) RIKEN Caption In a novel genetically engineered mouse line, dorsal subiculum excitatory neurons can be tagged with fluorescent proteins (e.g., GFP in green) or optogenetic proteins for behavioral manipulation studies. Blue staining shows the entire dorsal hippocampus, in which subiculum sits at the output.
