Red shows cell nuclei, most of which are dentate gyrus granule neurons. And white is GFAP immunostaining, which largely labels astrocytes but in this part of the brain also labels radial glia, the stem cells (or to be less controversial, “precursor” cells) of the hippocampus. Radial glia can be identified by the long process (almost like a dendrite) that they extend through the granule cell layer.
Via Functional Neurogenesis, excellent neuroblog.

Azurite crystals from Arizona seem to pulse with color. The mineral azurite—a copper ore—consists of blue basic carbonate. Azurite’s brilliant color adds to its popularity in creating semiprecious stones.

So this is an amazing thing we talked about in bio the other day. It’s a method called Brainbow. It’s really hard to track neurons when they can get so long and tangly, as you can see in this light microscopy of a mouse hippocampus, so scientists can mark each neuron with a different color of fluorescence via transgenes that produce fluorescent proteins. What a brilliant solution!
