Specimen: Eupholus weevil, dried thorax scales, stack of 80 images
Technique: Darkfield, 10x magnification

Specimen: Rat brain tissue
Technique: Brightfield

Specimen: Hydroid collected from kelp sample

Specimen: Adult mouse hippocampus, a region of the brain involved in learning and memory. Reactive astroglia (pale yellow) have proliferated and enlarged
in response to neuronal activity over time.
Technique: Confocal microscopy, Z-stack of 7 slices

Specimen: Immature mouse hippocampus, a region of the brain involved in learning and memory.
Technique: Fluorescent

Specimen: Marine plankton Petalotricha ampulla with cilia extended
Technique: Differential interference contrast microscopy
