NOS1 positive cells at the LM level in the Cortex and Hippocampus. Cells expressing TdTomato fluoresce in nNOS positive cells in an nNOS-CreER;Ai9 mouse. The TdTomato is rendered green in the images. (A) The nNOS positive cells make up a small population scattered in cortex and hippocampus. (B) A dense and diffuse plexus of neuropil can be seen throughout layer II/III and (C) throughout deeper layers of the cortex. Single arrows indicate axons and double arrows dendrites.
