Maximum intensity projection of an optical section series of a protoplasmic astrocyte injected with Lucifer Yellow from the hippocampal area CA1 in a 1 week old male rat. For more information, see: B...

Montage image of a brain stem from a Brainbow transgenic mouse. In Brainbow mice, neurons randomly choose combinations of red, yellow and cyan fluorescent proteins, so that they each glow a particular...

Laser scanning confocal micrograph of a water flea, Daphnia atkinsoni. This specimen has a "crown of thorns," a defensive trait induced in offspring only when the parents sense chemical cues released...

Adult mouse hippocampus, a region of the brain involved in learning and memory, showing reactive astroglia (pale yellow) that have proliferated and enlarged in response to neuronal activity over time....

Eyes and optic tectum of five-day-old zebrafish larva that has a mutation causing retinal axons to project into the olfactory lobe. This image was created from a 125-slice Z-stack that was collected ...
