Here's an image of the whole moth brain section. I stitched 35 200x frames together to make this (using ImageAssembler). The resulting file is about 30MB. I printed a 3-foot long panorama from the stitch which shows tons of detail (mostly of the air tubes). Unfortunately, by the time I had time to take this picture sequence, most of the stain had bled out of the brain and into the glycerine. Too bad. Again, this is brightfield with a 20x phaco.
The brain is about 4mm across. The two large outer structures are the optic lobes, and we already talked about the antennae lobes. The U-shaped opening at the center is the esophagus! The billions of black fibers are air tubes supplying the oxygen.
